Algae ruining my new planted tank.
I started a 55g planted tank just after Thanksgiving and I've gotten an outbreak of hair algae. It's mainly growing on the plants and is brownish in color. I have 108 Watts of T5HO lighting, pressurized CO2, canister filter, and an additional powerhead for more water movement. I started EI dosing before I had the CO2 stabilized which I believe led to the algae outbreak. I have Water Sprite, Wisteria, Anubias, Java Fern, Micro Sword, and Anacharis. The plants are growing well, but so is the algae.
For the CO2, I'm now running it for 4 hrs before turning on the lights which then stay on for 8 hrs. I have a drop checker indicating that my CO2 level is close to 30ppm.
I did a 60% water change last night which lowered my NO3 to under 10 ppm and my PO4 about 0.5ppm. I've since added a small amount of KNO3 to reach 10ppm.
Any suggestions on how to proceed from here? Should I keep dosing the Plantex CSM or should I wait until the algae loses a hold? How about the 8hrs of lighting, too much?
Thanks for any help.
