What kind of sand did you use? Live sand, play sand ????
A lot of you all will very disagree with me but i had to try It and it worked very well and looks white in my tank. I did a lot of reading and found some perfessor dude that brook it all down,,, any ways to make a very long story short I tryed it and im still useing play sand From lowe's (premium play sand) but It has to be only silaca quartz, Silacate sand had a very high,high diatom problem but the silica quartz did not have as bad . there are two or there are probibly more types of sand out there. I started trying it in a 10gal tank for 2 months and then I put it in my 55gal and I dont have a problem with it, but I had more problems when I was using cc, One fifty or so lb bag of sand only costed less than four dollars. But it had to Silica Quartz.
my snails and fish have no problem with it either.
