Some of the "playsand" contained silica in it I thought which could cause algae blooms? I thought I read that a while back. I could be wrong though.

Do a search on the board and you'll find a lot of info.

Target play sand is what you need. I have it in my freshwater tank and it is great. The cloudiness in our 150 gallon tall only lasted a couple of hours after adding everything. I think you get it at Home Depot at around $5 per bag.

Almost all commercial sand is silicate. Silicates grow diatoms. Diatoms are ugly. Therefore, don't use silicate sand in a reef aquarium. I'd also worry about what else was in "commercial grade" sandbox sand. Tons of things that wouldn't worry a kid will be bad for a reef.

its not like i'm just dumping in the sand, i'll rinse it out, plus if there is a problem my filter should be able to take care of it
