See Ive heard that the silicates found in sand doesnt break down into the water, the only downsides are its sharper, and algae as Mr x stated

I guess i would like to go with something safe, i dont want to go with something too fine as it can get stirred up too much and wont be sucked up when vaccumed.

I used the pfs as mentioned and have not had any algae issues in the 3 months or so it's been in there. I had a sand sifting goby for like 2 days and he was able to sift it easily enough.

I;m not sure if I got silica free pfs though. I have a silicate test that I ran and it came back at 0 so I don;t know for sure.

ive read that silica sand is chemically identical to the glass in your aquarium. thats why its ok to use it as your substrate.

Non-functional sand beds can be any depth,grain size etc. dsb depth is based on grain size.. Usually a smaller grain is used and anywhere bettween 4-6" I believe, enough to promote anerobic conversion of trates to non harmful nitrogen
