Today I did a lot of tank cleanup. Moving rocks, etc. it only split into three anemones all at one time. After cleaning out the tanks, changing up my fuge, and making some major adjustments to my skimmer, and building a DIY carbon, pad, phosban filter tube the tank is looking sweet. Ill post pics later. Why did it split? That's what they do. I check water parameters and found no phos, nit, ph, Kh, cal all great. Never saw my phos so low. Usually it hits at .25 now 0. So it just happens.
