- Is it true that coralline algae clogs live rock? 240 gal w/ 200lbs of pukani rock. I overfeed (but have 18 fat happy fish). Algae was NOT big a problem until I removed GFO and replaced with biopellets. FOWLR. PH 8, amm 0, nitrite 0, Nitrate 40 (just cut back to feeding 1x day), 1.023, point of sale .03 due to H2O water changes & GFO replaced back, chaeto in Bashsea media chamber 6-18 w/ grow leds (should they be on 24/7?), Bashsea twisted skimmer 8-24, Bashsea ss-48 sump, 2-Orbit marine IC pro 92 watt led's on 10 hrs ( I was told not to turn lights off it will upset water chemistry), turbo twist 36 watt UV on 24/7. I thought I had this. Obviously not. Besides the short algae on tops of rock, I noticed the beginning's of hair algae everywhere. I am open to any help.
