Carib SeaFlorida Crushed Coral, 40 lb.

Really nice substrate. Yeah it's dusty and needs rinsed a bunch but it's lovely natural material and looks white with my white oolitic sand

you must wash thru a window screen .a lot to remove the fine powder .or fish tank will look like a glass of milk

Very authentically pleasing and my fish definitely seemed to like them as well. Put a bit into my cichlid tank and they used these to build themselves a little structure when hiding their eggs

Did what was expected

I didn’t really know how to use this, but I put just a handful in my tank for my fish and it works. It’s really heavy and there’s a lot

Good price and did what I needed it to do. I use it for my snails and raising hardness is my aquarium

A handful in each aquarium stabilized my pH levels to about 7.5. I used an empty filter insert and placed them inside the filters. The water had little to no cloudiness for up to 30 minutes. My tanks are all overstocked and low PH used to be a weekly issue. Now it's no longer an issue.

The crabs love to keep it looking clean.
