I still have CO2 changes to make. Fluctuating CO2 levels, BBA. EI keeps most other algae at lower, healthier levels. If BBA would stay green I wouldn't mind it as much. I have reduced the light with some shade screen. One day I will get the 5lb tank set up. I need to go pressurized, but I am fond of the yeast reactor. It stays at about 6 or 8 psi. Kicked out some problems. I have and idea for a DIY to replace the Duetto. That would help. The best way to fight algae is to grow a plant in it's place.Biollante said:Hi Tug,
There really are two types of algae for the purposes of marine aquaria.
The micro-algae akin to what we have these are generally nuisance kinds, though can be used in scrubbers and so forth.
The other are the macro-algae, they are generally desirable.
... natural and looks nice.
