Sick of these threads yet? So I have had bubble algae popping up in my tank for quite some time now. I tested my water last night, and my nitrates are at about 10, and my phosphates were at .25, everything else was perfect. The rock I originally used had a huge bubble algae, and hair algae problem, and I scrubbed it for hours, although I'm sure there was still some left. This may have been a big mistake. Although I'm not terribly concerned about it at the moment, I can see it becoming a problem, so I'd like to take some precautions and preemptive strike. First thing I did was cut back my feeding. Pellets once a day, frozen twice a week, all leftover removed. I was feeding frozen and pellets every day, and not taking anything out. I have not noticed a difference, except maybe hungrier fish. (two weeks.) Started growing cheeto. (Month +) Got an Avast skimmer. This has only been running for 48 hours, and is showing positive results. I'm still dialing it in, so I'm skimming pretty wet, I think once I get it, right where I need it to be, it will make a huge change. (2 Days) Doubled my water change from 5 gallons to 10 gallons weekly, after doing a 25% about two weeks ago. (1 month) And of course, just picked it off as I go along. (1 week, on and off) I have contemplated emerald crabs. (none yet) Is there anything else I could be doing? Is there anything else I SHOULD be doing? Is it possible I have not just given it enough time? I don't want to beat a dead horse here, but I can't help but wonder if it's something I am doing, or if it just existed on my original rock and is able to come back. I had some caluerpa that I thought was completely eradicated after leaving it in a forum members tank for a day and letting the tangs loose on it, and I just noticed yesterday a small piece coming back. The caluerpa originally existed on the rock as well.
