Pool guy freaked about sand :/
Ok, so I went to my local spa & pool store today. Asked for pool filter sand, he pointed out some bags and I asked about the color because the bags weren't see through. He asked what I'm using it for & I explained it was for my aquarium. He kind of freaked out and said oh no, you don't want to use this, it's very sharp. He got some out & I said it looks very much like the aquarium sand I have in one of my tanks now (except it was white & I have Tahitian Moon). He said it's not, it's like crushed glass & would probably hurt my fish. I asked him exactly what is it & he said 20 grit silica sand. He suggested something called pavers sand. From the way he spoke I don't think he knew much about aquariums, but I left without it to come home and research more. Is that not the sand I want? I've had so much trouble trying to get my hands on BDBS & now pool filter sand that I'm about ready to throw in the towel & just buy more Caribsea sand...but the cost difference is just so much. Help?
