I have a 90 gallon tank with 130w of pc lighting. So far everything is going ok I have mainly low light plants jungle val ,crypts, anubias, java ferns, and micro sword. I already have a c02 system and was running it till the tank ran out. Growth has slowed since but the plants look ok. Im looking to add a little light to expand my options. Hd has two bulb t8 lights for a good price. If I add the new fixture and start running my gas again could I grow some more light demanding plants like rotalla and tiger lotus. I also want my micro sword to fill in more so I was thinking about moving my pc light directly over my foreground and using the t8 light for the taller background plants. Do you guys think this would work well?
