We set up a 70 litre tank 2 months ago using ADA Amazonia 2. We have used EI since the beginning using the recommended amount. Lighting at the beginning was 2x 24 watt T5s for 10 hours a day. We started getting lots of fluffy brown algae and got advice that we should reduce the lighting, crank up the CO2 (no fish in the tank) and double the EI dose. We did daily 50% water changes for the first week after set up and then 2-3 times a week for next 2 weeks.
We're still getting this fluffy brown algae plus some BGA and little plant growth. Any advice on how to flight this algae would be much appreciated. Thanks.
