Here are some pics from Day 14 - Still pretty much the same with brownish type algae (but more of it on screen). There are some nice green in two small spots (lower corner and then at the top of the screen). The top of the screen sometimes sticksout of water due to evap in sump area - so that is peculiar. I switched to a air bubbler instead of Venturi pump and also moved the screen closer to the glass (about 1.5" now away from LEDs). I did not wash the screen at all. What else should I do? Is this normal?
