Tank is just over 2 weeks old. I have dwarf hairgrass growing well as a carpet, some crypts, anubias and java moss on bogwood, and have just added some water lettuce. Brown spots of algae are appearing on leaves and in centre of tank on the dwarf hairgrass.
Details: Tank is Fluval Roma 125litre with 12 watt LED light that comes with the tank, plus a Fluval fresh and plant 32watt. I dont know the PAR or Lumens but will look it up. There is the usual fluval U3 litre, and a power head at the opposite side with a sponge on, this directs the CO2 to the front of the tank. The CO2 is a fire extinguisher with a bazooka atomiser. Tank pH was originally 7.4 but the CO2 dropped it to 6.6. I have a drop checker at the opposite side to the CO2 but I find it hard to read. Its dark green mostly. The CO2 is one to two bubbles a second.
Lighting photoperiod I originally set at 12 hours because I really like to see my fish, Im home all day. I realise that I have to reduce the photoperiod to avoid the brown algae. I cant work out whether to just use the fairly dim 12 watt light for 12 hours but time the 32watt to just do 6 hours. Im a bit disappointed because I thought by adding CO2 I might avoid the algae, but I presume it means I havent got the balance right yet.
What shall I do?
