So I have this algae growing on this piece of rock, this and a couple others were bought months ago, cured at the LFS, only appears to be growing on this one rock nd starting to grow on the hammer sitting in the rock that was just placed there Saturday. The reddish, purple stuff is my main concern, then green stuff is showing up on the rocks nicely, Best guess would be coralline. Also look at the bottom right sand, some is growing there. Do I need more flow? All important tests, test at zero, however I do not yet own a phosphate test kit, which I will soon get. Also the last water I got, I am not sure of as the filters may not have that high of a rejection rate, though this purple stuff was growing before that batch of water. Need to get my RO/DI setup.
Thanks!
Thanks!
