My parameters are around
Calcium: 455-465ppm
Alkalinity: 10.5-11.5dkh
Magnesium: 1365-1380ppm
Ph: 8.4
Ammonia: 0ppm
Nitrite: 0ppm
Nitrate: 0ppm
Salinity: 35-36ppt
Temperature: 79-84°
I haven't done a water change in 6 weeks and nitrate haven't moved. I have some macro and the skimmer is a reef octopus 150 I haven't cleaned in a week and the macro isn't hardly growing. So I don't think there is hardly any extra proteins in the water column. I also don't over feed my fish cuz all of them are a bunch of little fatties. There are a couple of coral in my tank that are doing great as in my cabbage leathers, mushshrooms, montipora, duncans, pipe organ, and my chalice (is doing the best though probably 12-14inchs in 8 months). But some corals like the frogspawn, starpolyps, birdsnest, and candycanes polyps are in full bloom and just not growing. My xenia was growing like a weed but now it dwindle down to two clusters. Im not worried about the xenia though. Everyone says how easy theirs grow and way easy for beginners to culture. I m just keeping them alive I feel. I could really use any input on these. Are my parameters reasonable, would I be better off getting rid of my macro (chaeto and. Grape caulerpia), should I not run the skimmer all the time. I don't mind doing water changes if I needed to but u can see maybe why I haven't. This whole setup was up and going for about 14 months now under four 40 watt t12s (2 act., aquasun, and 50/50) and one 175 w. (14k)metal halide. I know this probably isn't the greatest lighting but its either that or 2 400 watt metal halide. Keep the suggestions coming, thanks. Any replies are welcome.
