CLASSIC SAND & PLAY Natural Aquarium Sand, 20 lb

CLASSIC SAND & PLAY Natural Aquarium Sand is a fine substrate sold in a 20 lb bag. It’s washed and kiln dried to cut down on dust, and it’s listed for both freshwater and saltwater tanks. The natural shade gives a soft, neutral backdrop for colorful fish and green plants.

Fine texture

Fine sand suits fish that sift or dig, such as corydoras, loaches and many gobies. Waste tends to sit on top of sand rather than sinking in, so it’s easy to siphon off during water changes.

Pre-washed, still rinse

The sand is pre-washed to remove impurities. Even so, give it a rinse in a bucket before adding it. Stir, pour off the cloudy water and repeat until it runs fairly clear. Fill the tank slowly over a plate so the stream doesn’t stir the bed.

How much to buy

A 20 lb bag gives a thin layer in a mid-size tank. For a deeper bed, or if you plan on rooted plants, you’ll likely need more than one bag. Plants will grow in sand, but root feeders like the Seachem Flourish Tabs help since plain sand holds few nutrients.

Safe for fish and plants

The brand lists it as safe for fish, plants and decor. It’s natural sand rather than dyed gravel, so there’s no coating to wear off.

Colors

This page covers the Natural color. The line comes in seven different color options if you want stronger contrast.

Keeping it clean

Hover a siphon just above the surface rather than plunging it in, or sand will be pulled up the tube. A gravel cleaner like the QZQ siphon kit works if you keep the tube high and pinch the hose to slow the flow.

In saltwater

For reef tanks, many keepers prefer aragonite, which helps buffer pH. Plain sand like this works well in fish-only setups.
