Hey forum, new scrubber guy here :-)
I build a UAS scrubber like the HOG but i haven't seen any growth in over a month.
Scrubber without bubbles
36watt led lamp
I am only getting light brown stuff on the screen, but then again my PO4 is 0,00 ppm, I have been dosing NPK fertilizer to promote algae growth but nothing is helping, my NO3 is rising a little.
There fore I can use a little guidance...
Let my know if you can't read/understand as English is not my best language :-)
