This algae growth is alarming. Long strands of the filamentous stuff are attached to all the plants and from time to time they break off and clog filter inlets. I need to clean the inlets every day without fail. Until recently I thought BGA only formed a slimy film, but now I learn that is not the only form it takes. I am beginning to suspect that this could be BGA:

The algae looks grayish in the water but once removed it looks quite dark and, might I say, bluish-green. It is not hard to remove it from plant leaves.
The tank has 100G actual capacity, is well stocked with Malawi cichlids and some larger clown loaches. It has plenty of biological filtration. I am doing EI for macronutrients and add Flourish Trace to recommended level, and iron to test. Nitrate tends to run around 25ppm according to a Tetra kit.
