Not really grow lights, but I do have an extra aquarium light down there. Its on the same timer as the tank lights. The marimo balls don't take too much light.festerfish;4173290; said:do you have grow lights in your sump? water wisteria and stratiegeic algea growth will help keep the nitrates down
I haven't tested my nitrates in awhile. I probably should now that I've taken out the large rtc. I took the tsn out as well, but they didn't get along so well together in the 210, so after a night, he went back in the 450.
I'm hoping to set up an automatic drip system soon. I keep putting it off. When I set that up, I want to pull the sump out and fix the design a bit. Probably also redo my plumbing as well.
