Re: Reddish brown film growing on one plant and fish cave... Algae is normal occurance in a newly setup tank. In time, as the tank matures, it will evenually go away. It is most likely diatoms or brown algae.
However to keep it away you will need to be consistent in your fertilization, water changes, filter/tank maintenance & lighting schedule. Your also going to need to upgrade your lighting so the plants get the proper type/wattage so they can grow at their best. |
