Basics: 75 gallon heavily planted, CO2
injected, 3.5 wpg
for 9 hours, dosing with Watson ferts, parameters good and tank generally running exceptionally well thanks to all the advice on these forums.
The only problem I am having is consistent marble sized growths of hair algae in a field of dwarf hairgrass. No other algae types or problems in other areas of the tank.
I have been just pulling out the algae but it reeks havok on the hairgrass as it is easily pulled up as well. I have thought about using Exel to combat the algae but have a few questions.
1. What dosages are people using to obtain algae control?
2. Are the algae control properties due to an algicide property of the excel (glutaraldehyde?) or due to the other plants being able to outcompete for the nutrients in the tank?
3. Will this help, even when dosing Co2
I wouldn't worry about it too much other than I am about to add 5 discus to the tank (currently in quarantine) and I want the tank to be as ideal as possible before adding the discus.
