I have a 125G that was set up about six months ago with about 80lbs of dry Cerameco Vidarock and dry Tropic Eden sand. I have had REALLY bad diatoms for going on 3 months now. I am positive it is diatoms. After doing some searching it seems that the Vidarock is notorious for leaching silicate for an extended period of time. I have never had silicate issues before the rock and my rodi is TDS 0 and has been tested for silicates in the past, so i know the rodi is not the source.
I have read that Phosguard might be better than GFO for removing silicates in particular. Just wondered if there are other/better options, or if Phosguard is the way to go.
Remember that this is a fish only, so i am not worried about harming corals.
Thanks!
