an alternative to southdown

ok, i finally found an alternative to southdown play sand. i went to my local home depot and they carry "best premium" play sand by garick. it is a silica based sand and the lady i spoke to at garick (very helpful) stated that may people use it in their aquariums. my question is since it is made of silica what can i use as a ph buffer that i wont getting since my sand is not aragonite or calcium based? what can i expect from my aquaium by using silica based sand? i heard about possible diatoms but i know that is still a debate.

thanks for your help

IMO The buffering effect of aragonite sand is negligible. Just monitor your alkalinity and calcium and adjust as necessary. The sand crystals in silica sand may have sharper edges than the aragonite sand and this can sometimes irritate sandbed dwellers (ie worms, snails etc.)

I use silic playsand in my tank and so far i actually have less diatoms than i did using the aragonite in my 55......as far a ph buffering i dont think it will be a problem as long as you do regular water changes and keep up with calcium and alk levels as jackdp pointed out.

Actually, my silica sand is much smoother (ie less sharp edges)
than my aragonite. I think it depends on the manufacturer.
