I let my po4 get pretty high and red slime started to bloom. I tried 4+ water changes and vacuumed as much out as I could each time. The phosphates were reduced to .025, nitrates to 15 and have maintained it at this level for over two months - red slime still blooms...
I tried a regiment of Dr. Tim's Re-Fresh and then Waste-Away for several weeks without much improvement. Then I tried a dose of Chemi-Clean. It worked very well. After one dose, and 48 hrs later all traces of cyano are gone!
Now, I can't get my skimmer back under control. I waited another day, added fresh carbon and did a 30% water change. The skimmer is still erupting with a river of very wet foam with it turned down all the way.
I raised the skimmer about 3+" and have it overflowing into a 5 gallon bucket. Hopefully it will settle down soon. Anyone have any tips for getting it under control?
