Thanks for stopping in. Believe me I am aware of the lack of accuracy with the API kits. The plan is to get Hanna checkers and Salifert or Red Sea to fill the gaps in what Hanna offers. Chaeto has seemed to be very effective in reducing both No3 and Po4 in the reef tank. I have seen the results on my personal tanks and otherw report simliar results. I know po4 is less than the API's .25 and that no3 is not true 0 but likely under 5ppm. No3 has stayed at 10ppm until this week I saw it drop. No other changes with the exception of having a dense growth of chaeto in the fuge in about 2 weeks time since adding the chaeto. I dont really have anything else in the system that would be consuming the no3, maybe bacteria deep in the rock. I dont have a lot of rock and most of it is not very dense. No water changes have been done since the first one a few weeks ago, I see no reason to need a water change.The refugium does little to remove nitrates; I suspect something else is the cause for that (test error or the kit lacking accuracy to measure below 10ppm) especially since the phosphates showed little change. Setup is looking really nice though; you've left plenty of room for the corals to grow out (something most of us forget to do).
