Rated 2 out of 5 by SisterMidnight Not very good. Turned my water into tea
I rinsed this sand throughly before I added it to my tank. It look great and the fish seemed happy, but I noticed that the water, though clear had a noticeable tint. I did a partial water change three days after adding this sand to the tank and the water looked like tea. It was so brown. Normally I do a 30% water change once a week. After I saw how dark my water was I did a 75% water change. The tank looked great and the water was again clear. I've continued doing my normal 30% weekly water changes, and every time I drain the water it is noticeably tinted brown. I've had this sand in the tank for 2 months and my water still looks like the tea after a week. It seems to be a purely aesthetic issue and my fish have remained healthy and happy. They love sifting through the sand. I just wish my water was clear and clean like it was before I changed my substrate.

Rated 5 out of 5 by BadTouchTrio1 Just What I Wanted
I wanted sand for my goldfish aquarium. Something that they could sift through, but wouldn't get sucked up by my gravel filter. Something that wouldn't compact and make air pockets, but fit enough to prevent gink build up. And then I found this, and was amazed. It is exactly what I wanted, and looks beautiful in my tank.

Rated 5 out of 5 by Stitch1 Amazing Sand!!
This sand is amazing! I bought a 5 pound bag for the 3 chambers of my betta falls aquarium. Which i think only used 1 pound of it because i wanted to put glass rocks on the bottom for the light in the bottom to shine through. Then i used the rest for my 10 gallon which had gravel filled only halfway. I put the sand on the bottom, then put the gravel on top of the sand on the sides of the aquarium. Looks great!!

Rated 1 out of 5 by BettaOwnerCA Raised water pH from 7.6 to 8.8
I recently purchased the black sand. It was beautiful and looked good in the tank...but raised the water pH from 7.6 to 8.8!! This is the level only specific kinds of fish can live. Many fish can be dead. Although there is a warning "minerals in the sand may affect the water pH" on the package, this much of difference is not acceptable. Substrates for general use should be much safer.
TEST THE WATER BEFORE ADDING ANY FISH. If you don't have a test kit, Petsmart can test the water for you. If it's safe, that's great. If not, return it and get a different substrate for fish's sake. Adjusting pH with solutions is not recommended.
