Hey prime311, does your monster chaeto farm reduce the nitrate & phosphate levels in a predator tank? What's swimmin in your set up? How many gallons is the main tank? How big is the fuge? How do you run your lighting on the fuge? I figure if I become a water quality nut, I can reduce the amount of algae buildup & the frequency of water changes. Nitrates run between 20 & ketchup on my nitrate test kit. Phosphate steadily rises too. I have some inverts in the fuge. I know they are more sensitive.I have a dozen fuzzy chitons eating algae off the rocks w/o being eaten by my several triggers & pred wrasses. Some larger Mexican turbos are still around but several have been picked clean. When my money pit becomes an algae slime pit, it upsets the wife. When it's clean, she doesn't mind the money spent as much.
