Aquarium Advice Regular
I rescaped my 20 gallon tall community tank about 3 months ago. I took out all of the artificial décor and added a glass canopy, coralife light with 2 T5 6700k bulbs, drift wood, java fern, Anubius nana and Amazon sword. I have a medium gravel substrate and only use fertilizer tabs for the Amazon sword. I use 2 bubblers in the back of the tank cause I read somewhere that it would keep the CO2 level high enough without having to inject CO2. The plants have been doing great until this week when I noticed black beard algae growing on the Java fern and black along the edges of the Anubius. I'd rather not have to inject CO2, but I will if I have to. I need suggestions before the algae gets out of hand. Would reducing the light level do the trick without affecting the growth of the plants? If I inject CO2, do I need to remove the bubble bars? What about dosing liquid carbon? Any advice would be welcome.
Thanks
