Hi,
I have 180L Rio which is heavily planted.
After battling brown diatoms and overcoming it, I now have a problem with GSA, which has been in my tank for several weeks.
It started with my Anubias and I upped my PO4 to 2x suggested EI dose, which does not seem to have improved things, so I upped it to 3x suggested EI dosage about two weeks ago. It has now spread to odd leaves on nearly all the plants and it has started to appear in small amounts on the glass.
My flow/distribution and CO2 is the best it has been and I have plenty of surface water movement and my plants are growing freely which need trimming at least once per week.
Apart from some algae under the substrate at the front of the tank (cyno?) my tank appears healthy with plants and fish doing well.
Should I add more PO4? as according to the calculator on James Planted Tank it is about 6ppm already, but I think I read somewhere, maybe on Barr Report? to increase PO4 by at least 3x to eradicate this stuff.
What do others think? Or am I destined to have some GSA at all times?
I am doing a PH profile during the day today.
Just to add that I am also dosing 9ml of liquid carbon daily!
Edit...I also reduced my lighting period from 7hrs to 6hrs.
