Hey all, so I'm at my wits end with this algae. The tank is almost a year old. I had this problem previously, decided to trim everything in a big way, physically remove as much as I possibly could and change my dosing a bit.
Right now I'm using TAP water for weekly 50% changes. One thing I know for sure is my water is HARD, it's city water, not well.
75 Gallon
C02 injected, controlled by a PH controller (PH is kept around 6.1 during the day, CO2 shuts off at 4pm with lights.)
Lights run for 7 hours, from 9am to 4pm.
Twinstar 1200SA light
Twinstar Algae inhibitor (clearly does nothing)
Water kept around 78 degrees
I dose slightly less than recommended with THRIVE
Parameter wise, everything is nominal. Nitrates hover between 30-50 depending on day. I do see good plant growth, but eventually all leaves get covered in this "Filamentous algae", and plant growth stunts. I have also tried Seachem Excel, two caps a day for the past three weeks, with no change. I'm wondering if at this point it's just my tap water and I'm doomed. I do have a few Amano shrimp - two large and five or six small. Wonder if I should just get an army of them. Or maybe I should be dosing more? Right now it's five pumps of THRIVE three times a week.
You can see it's covering the substrate (Eco-Complete):
