Does an air stone which goes on after Co2 goes off cause algae? I keep getting staghorn only on the side where my airstone goes on.. coincidence? Maybe?
What size is your tank? Try to reduce your dose by 0.5-1ml and see how it goes. Staghorn should clear out after this. Once it goes away stick to a dose that doesn't cause Staghorn to appear.Yes I am dosing 3ml of APT complete every other day
