I currently have a rock substrate in my 35 gallon tank and I have had a diatom problem for over a month now, I use tap water in this tank. I have a 5 gallon betta tank with white sand substrate that also uses tap water and that tank is crystal clear. So I'm think about changing my rock to pool filter sand, is that an advisable change? I've read that silica sand can cause a diatom bloom since the silica can dissolve into the water over time and fuel the bloom. Is sand any harder to keep clean than rock? Thanks for the help!
