from what i hear. silica is glass? and it can kinda cut the belly. ive seen some rays on silica sand and they have little red bellys. thats what ive heard
i know about the crushed coral but i had it in there when i was SW . My water parameters are good but i think i might go with an all sand bottom . I just need to find a different kind of sand . I didn't even realize this stuff had silica until i read on here and saw it was bad so i went and checked the bag of sand and sure enough . i'll make a trip to homedepot today and see if they have any white non-silica sand
I use Black thai sand.....But if you wnt a nice white sand, check you local pool supply company and get pool filter sand
