Been awhile since I updated on my tank and there's been a lot of changes. I really wanted more sps so I tried to accomidate. So what do sps need? Stability, mh, skimming, and random flow. Needless to say, this is damn hard w/ such a small tank .
Grabbed a 70 watt mh 14k setup that sits ~5 inches from the surface. Temp control is ghettoed out with a big wall fan nearby set on the same timer as the mh. Gravity ATO with a small amount of kalkwasser (learned the hard way not to mix high strength kalk, and wouldn't use it if there weren't so many sps in the tank now).
I ditched the big fuge AC30 and nabbed a rio nano skimmer. It was only 10 bux used but I can honestly say to anyone and everyone DON'T GET ONE! Yeesh, its the most ineffective and tempermental piece of machinery I've ever owned. Microbubbles are controlled with a ton of filter floss, and it still leaks out a little. I don't think it would effectively skim anything larger than a 5gal .
The flow is somewhat randomized b/t the rio and a the mini powerhead. I threw an old hob powerfilter on the side to stick some macro and phosban on an alternate light schedule.
Water changes are 30% 1-2x a week, scripps. Keeping a hungry sun coral, mini carpets, gonio, and carnation is damn difficult with the sps; but the water changes seem to help.
