Can concrete be used in aquariums?
Type 3 Portland cement can be found at most hardware stores. Mix one part cement and three parts play sand or fine gravel together. The mix should form into a ball and feel like Play-Doh. Crushed shells and aragonite sand can also be toxic to fish, and should not be used when making aquarium rock.
How do you make a concrete aquarium safe?
All portland cement products are aquarium safe. This is basically every cement/concrete mix you will find. Just avoid anything that says “modified” or “polymer modified”. The drawback is that it must be cured for at least a month before it is stable enough to not cause changes in your pH.
Is cement toxic to fish?
A. Concrete ponds can be “cured” and made safe for fish without any special coatings. Wait a week after the final pond refill and then test the pH. Then place some fresh tap water in a bowl and let it sit overnight to allow oxygen and carbon dioxide levels to stabilize.
How do you make a concrete pond safe for fish?
TO CURE – Newly cemented ponds release quantities of free lime into the water which is toxic to fish and plants. By curing the pond, this danger is removed. To cure, mix one-gallon household vinegar to each 200 gallons of water in your pond and let set three days. Empty and rinse thoroughly.

Can you use quikrete in aquarium?
The quikrete will be fine. Most people don’t like it as well because you lose detail, due to the thickness of the cement, and the time and water changes needed for it to cure. Too many fish to choose from, too few tanks!
