its been 2 weeks, i havent seen any change at all, still stuck on the rocks very well too.
Pull the green, brush the rock.
4-25% water changes in a week
Start GFO
When phosphate is down to below .1 and you are providing the correct amount, color and length of photoperiod, your GHA will not return.
Reduce feedings (largest contributor to phosphate) and maintain a 10-15% water change weekly.
Also makes sure nitrate is below 5ppm and PH runs 7.8 -8.3
