Is it true that if you have limestone you will have green water? I heard it is because of the particles in the water from it dissolving, if you did have it in and dtake it out, would the particles be slowly removed from the water? Because in my filter I've found places where it looks like mud or clay has built up in certain pockets of my bog-filter. I've felt it and I'm positive it's mud. If I remove the limestone will the green water I have slowly go away as the particles get filtered out?
