Hmmm... I found this:
Silica sand
Hello,
I am new to this site and I am sure you have already encountered this
question before, but please bear with me. I currently have a 75 gallon with 3
small frontosas, 3 clown loaches, 1 Syndontis catfish, and 1 Pleco. I had
aquarium gravel in this tank but upon reading articles about these fish I found out
they prefer sand substrates. Many sites have said that you can use pool
filter sand as a substrate and I bought some.
<Mmm, pool filter sand? I don't agree... siliceous materials are bad to use on a few counts... they're too sharp (hard on your loaches), too slick/smooth and pack down due to their two-dimensional structure (bad for biological filtration), and do naught for alkaline buffering (unlike carbonaceous materials...)>
After cleaning it really well
stirring it with my hands, I noticed little cuts on them.
<Bingo>
Finding more sites, I now read that silica is actually sharp and will injure my fish, yet you said
at one time you used sandblasting sand. Isn't silica the same thing?
<Maybe in some localities, yes... but not in all>
Is there a sand more suitable that isn't as costly as what my LFS is charging?
Thanks,
Wanda
That to me says pool filter sand isnt safe for the fish. Am I totally off here?
