Cleaning Gravel in a Heavily Planted Tank
Consider NOT cleaning your gravel at all! I rarely "clean" gravel.
Count my vote with Bruce on this one. Flourite is great, Flourite plus a year's
worth of mulm is better. Ask me next year how much the plants like Flourite plus
two years of mulm!
Of course, I'm talking about a heavily planted tank with CO2. My
quarrantine/breeding tank and my daughter's betta tank get regular, complete
vacuumings, about half the tank each water change.
