After about a month of trying new things, I am starting to get most of my algae under control. What seems to be sticking around is this algae below. Most of it is greenish brown some is clear almost. It just doesn't seem to want to go away. my levels are: Ph 8.4 ammonia 0 Nitrite 0 nitrates 0 Calcium 440 dKH 9 phosphate kind of hard to tell the colors on this but it is definitely between 0 and .25 looks more like 0 though. As always any help is much appreciated so any removal ideas are welcome.
