Once the plants are in, the fish have settled and the water is clear, nobody wants to pull everything out because the sand is too sharp, too dusty or simply the wrong colour. So it really pays to get it right the first time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I have used sand in all kinds of tanks over the years, from small shrimp setups to big planted scapes full of corydoras. In this guide I will walk you through the best aquarium sand you can buy at Bluviva, what each one is good for, how much you need, and how to add it without turning your tank into a cloud. Every sand here is one we stock, so you can check it and order it straight away.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Makes a Good Aquarium Sand?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Not all sand is the same. Builder&#8217;s sand and play sand can hold dust, sharp bits and even chemicals, so they are a gamble in a fish tank. Aquarium sand is washed, sorted and made to be safe for fish. Even so, there are a few things worth checking before you buy:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Rounded grains.<\/strong> Fish like corydoras and loaches dig with their mouths and the small feelers around them, called barbels. Sharp grains can hurt them. Round grains are gentle.<\/li>\n\n\n\n<li><strong>Inert.<\/strong> This means the sand does not change your pH or water hardness. Your water stays the way you set it.<\/li>\n\n\n\n<li><strong>The right grain size.<\/strong> Very fine sand looks smooth and is great for diggers. Slightly bigger grains let water move through more easily and are a little easier to clean.<\/li>\n\n\n\n<li><strong>Low dust.<\/strong> All sand needs a rinse, but good sand clears quickly.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">All five sands below tick these boxes. The main differences are colour, grain size and price, so the best choice really comes down to your fish and the look you want.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The 5 Best Aquarium Sands<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. AquaEL Quartz Sand 0.4-1.2 mm: Best All-Rounder<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you only want one sand that works in almost any freshwater tank, this is the one I would pick. <a href=\"https:\/\/bluviva.com\/product\/aquael-quartz-sand-10-kg\/\">AquaEL Quartz Sand<\/a> in the 0.4 to 1.2 mm size sits right in the sweet spot. The grains are small enough to feel soft for bottom fish, but big enough to let water flow through them. That means fewer dead spots and a sand bed that stays healthy for longer. It has a light, natural colour that suits community tanks and planted tanks alike.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is also the best value sand in our range. It comes in a 10 kg bag, plus a <a href=\"https:\/\/bluviva.com\/product\/aquael-quartz-sand-2-kg\/\">2 kg bag<\/a> for nano tanks or topping up. It is inert, so it will not change your water, and it is the same sand we chose for our <a href=\"https:\/\/bluviva.com\/product-category\/aquariums\/aquarium-kits\/\">aquarium starter kits<\/a>. AquaEL also makes a 1.6 to 4.0 mm size, but that is closer to fine gravel than sand, so I would only use it at the back for plants with big roots.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> beginners, community tanks and planted tanks with root tabs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. AquaEL Quartz Sand 0.1-0.3 mm: Best for Corydoras and Shrimp<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The same <a href=\"https:\/\/bluviva.com\/product\/aquael-quartz-sand-10-kg\/\">AquaEL Quartz Sand<\/a> also comes in a much finer 0.1 to 0.3 mm size, and this one is a favourite for fish that love to dig. Corydoras, kuhli loaches and other sand sifters push their faces into the sand to look for food. With grains this fine, they can sift it through their gills just like they would in the wild, with no risk to their barbels. It is a fine white sand, so it also gives you a clean, bright floor for very little money.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is one thing to know. Very fine sand packs down more tightly than coarser sand. That is fine in most tanks, but you should stir it lightly every week or two when you clean, and keep it no deeper than about 5 cm. This stops pockets of stale water forming under the surface. If you keep shrimp or bottom fish, this small bit of care is well worth it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> corydoras, loaches, shrimp tanks and white sand on a budget.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. JBL Sansibar River: Best Natural Look<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/bluviva.com\/product\/jbl-sansibar-river-5kg\/\">JBL Sansibar River<\/a> is the sand I reach for when I want a tank to look like a real stream bed. It mixes light and darker grains, so it looks natural rather than flat. It also hides a little dirt between cleans, which is a nice bonus if you do not want to siphon every few days. It suits biotope tanks, nature-style scapes and any tank with wood and stones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Like the rest of the JBL Sansibar range, it is a pure natural sand with no plastic coating and no dye. The grains are rounded and gentle on barbels, and it is inert, so your pH stays put. It comes in a 5 kg bag, which is enough for a thin layer in a small tank. Most 60 cm tanks will need two or three bags for a proper depth.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> natural and biotope scapes, sand sifters and tanks with wood.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. JBL Sansibar White: Best White Sand<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/bluviva.com\/product\/jbl-sansibar-white-5kg\/\">JBL Sansibar White<\/a> gives you a bright, clean floor that makes fish colours stand out. Red, blue and black fish look amazing against it, and green plants really pop too. It is made from fine, rounded natural quartz, so it is safe for corydoras, loaches and shrimp, and it works in both freshwater and marine tanks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It comes in 5 kg and <a href=\"https:\/\/bluviva.com\/product\/jbl-sansibar-white10kg\/\">10 kg<\/a> bags, and the 10 kg bag is the better buy for anything bigger than a nano tank. The one downside of any white sand is that it shows fish waste and brown spots more. A quick hover with the gravel cleaner during your weekly <a href=\"https:\/\/bluviva.com\/stop-the-stress-the-budget-friendly-guide-to-safe-water-changes\/\">water change<\/a> keeps it looking fresh.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> colourful community fish, modern scapes, and marine or freshwater tanks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. JBL Sansibar S&#8217;Now: Best Bright Sand for Aquascapes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/bluviva.com\/product\/jbl-sansibar-snow-5kg\/\">JBL Sansibar S&#8217;Now<\/a> is the whitest sand in our range. It is very fine, with JBL listing the grains at 0.1 to 0.6 mm, and it has an extra-bright finish that bounces light around the tank. Aquascapers love it for the white path or beach look, where a bright strip of sand runs between rocks and plants and leads your eye through the scape.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It costs more than the other sands here, so I would not always use it for the whole floor of a big tank. Instead, use it where it makes the most impact, such as a front strip, a path or a small open area. It comes in 5 kg and <a href=\"https:\/\/bluviva.com\/product\/jbl-sansibar-snow-10kg\/\">10 kg<\/a> bags. Like the rest of the Sansibar range, it is inert and gentle on bottom fish.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> nature-style and Iwagumi scapes, sand paths and show tanks.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can You Grow Plants in Sand?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, but you need to feed the roots. All of these sands are inert, which means they hold no plant food. Plants that feed mostly from the water, like java fern, anubias, mosses and floating plants, will grow fine without any help. Plants that feed through their roots, like Amazon swords, crypts and vallisneria, need a little extra.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are two easy ways to do this. The first is to push root tabs into the sand near each plant every few months. You will find these in our <a href=\"https:\/\/bluviva.com\/product-category\/plant-care\/substrate-fertilizer\/\">substrate fertiliser<\/a> range. The second is to lay <a href=\"https:\/\/bluviva.com\/product\/tropica-aquarium-soil\/\">Tropica Aquarium Soil<\/a> under the planted areas, then cover it with sand. This gives you rich soil where the roots grow and clean sand on top where the fish dig.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Much Sand Do You Need?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A depth of 3 to 6 cm suits most tanks. Go for the lower end at the front and in fish-only tanks, and the higher end at the back where plants root. To work it out yourself, multiply the length by the width by the depth in centimetres, divide by 1,000 to get litres, then multiply by 1.5. Aquarium sand weighs about 1.5 kg per litre, so that gives you the weight in kilos.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Tank footprint (length x width)<\/th><th>Sand needed at 5 cm deep<\/th><th>Bags to buy<\/th><\/tr><tr><td>45 x 27 cm<\/td><td>about 9 kg<\/td><td>one 10 kg bag<\/td><\/tr><tr><td>60 x 30 cm<\/td><td>about 14 kg<\/td><td>one 10 kg bag plus one 5 kg bag<\/td><\/tr><tr><td>80 x 35 cm<\/td><td>about 21 kg<\/td><td>two 10 kg bags plus a small top-up<\/td><\/tr><tr><td>100 x 40 cm<\/td><td>about 30 kg<\/td><td>three 10 kg bags<\/td><\/tr><tr><td>120 x 40 cm<\/td><td>about 36 kg<\/td><td>four 10 kg bags<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">These are rough figures. If you want a slope from front to back, buy a little extra.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Rinse and Add Aquarium Sand<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Even pre-washed sand carries fine dust from the bag, so always rinse it first. It takes a bit of time, but it saves you days of cloudy water.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Put a few kilos of sand in a clean bucket. Never use soap.<\/li>\n\n\n\n<li>Fill the bucket with tap water and stir hard with your hand.<\/li>\n\n\n\n<li>Pour off the cloudy water and repeat until the water runs mostly clear.<\/li>\n\n\n\n<li>Add the wet sand to the empty tank and shape it, higher at the back and lower at the front.<\/li>\n\n\n\n<li>Lay a plate or a plastic bag on the sand and pour the water slowly onto it.<\/li>\n\n\n\n<li>Switch on the filter. Any light haze should clear within a day or so.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">How to Keep Aquarium Sand Clean<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Sand is easier to keep clean than most people think. Waste sits on top rather than sinking down between the grains, so you only need to hover your gravel cleaner a centimetre or two above the surface during each water change. Do not push it into the sand, or you will suck up sand along with the dirt. Now and then, gently stir any thick areas the fish never dig through with your fingers, and you will not have trouble with trapped gas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One more tip: do not use an undergravel filter with fine sand, as the sand can block the plates. A good <a href=\"https:\/\/bluviva.com\/product-category\/filtration\/\">internal or external filter<\/a> does a much better job and keeps your sand bed clean.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQs<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Is sand or gravel better for an aquarium?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It depends on your fish. Sand is better for bottom fish like corydoras and loaches, because they can dig and sift without hurting themselves. It also gives a smooth, natural look. Gravel lets water move through more freely and suits tanks with big, messy fish. For most community and planted tanks, a medium sand like AquaEL Quartz Sand 0.4 to 1.2 mm gives you the best of both.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do I need to rinse aquarium sand?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Even pre-washed sand picks up dust in the bag, and that dust will cloud your water. Rinse it in small batches in a bucket until the water runs mostly clear. It usually takes several rinses. Never use soap or cleaning products, as they can harm your fish.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is white sand hard to keep clean?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">White sand shows fish waste more than darker sand, but it is not harder to clean. A quick hover with a gravel cleaner during each water change keeps it bright. If you would rather not see every speck, a mixed sand like JBL Sansibar River hides dirt better between cleans.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I use these sands in a marine tank?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The JBL Sansibar sands work in both freshwater and marine tanks. They are inert, so they will not raise pH the way coral sand does. That makes them a good choice for a fish-only marine tank or a clean, white look.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I mix two colours of sand?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, and it can look great. Many aquascapers use a natural sand for most of the floor and a strip of bright white sand for a path. Over time the two will blend a little at the edges, so place a few stones along the line if you want to keep them apart.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Final Thoughts<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The best aquarium sand is the one that suits your fish and the look you are after. For most people, AquaEL Quartz Sand 0.4 to 1.2 mm is the easy, low-cost choice. Pick the 0.1 to 0.3 mm size for corydoras and shrimp, JBL Sansibar River for a natural stream bed, JBL Sansibar White for bright colours, and JBL Sansibar S&#8217;Now for that show-tank finish.
