Felicity Oliver –
The sand settled well in my 55-gallon tank and didn’t disturb the water chemistry. My dwarf corydoras and snails are active and happy. It looks natural and feels smooth under the tank.
Pippa Rutherford –
Great for burrowing fish. The grain size is just right and the sand doesn’t clump. I’ve used it in a brackish setup with good results.
Jessica Quinn –
Easy to mix into the substrate. No pH changes after adding it. My shrimp are thriving and the tank looks more like a jungle environment.
