Pool Filter Sand...Dangerous?!?

I've used it in many of my own tanks with no problems at all. I didn't have any trouble finding sand that wasn't treated.

As H3D and I have said, there is NOT a problem with untreated pool filter sand. It is the treated pool filter sand that IS a problem because it is treated with chemicals that are toxic to fish.

:wall: :silly:
 
Let your fingers do the walking and look in the local yellow pages. There has to be at least one other pool/spa place other than the one you went to. Call and ask if they carry both treated and untreated filter sand.
 
Silica based pool filter sand, about #20 mesh is a good way to go.

Ultrafine sand gets you into problems w/ cloudy water, irritation of mucous membranes (us & fish) etc. etc.

DE (diatomaceous earth) is also very fine and at least as abrasive as very fine silica sand, and it therefore to be avoided (there's also the carbonate leaching to consider in the long run).
 
I got a 50lb bag of plain Silica Sand for $6 at Lowes here.
 
what about quikcrete's play sand??? is that okay??
 
Whichever kind you get, make sure it doesn't say anything about inhibiting growth or treated for this and that and you should be fine. Also, make sure that it doesn't contain any limestone.
 
I used Quickrete Medium Grade Contracters sand. But it takes a while to clean out all the finer particles. Its will suck up into the gravel vac also so I just skim the top of the sand off and then run a wire hanger through it to release any potential gas pockets. A ton of MTS helps out also.
