Macroalgae Nitrate Export

[bioload]

At the moment the only lighting for the algae is an adjacent window, but I doubt if the tank is getting any direct sunlight though. Once I can get my hands on some rigid tubing (one of those boxes in the basement) I'll lower the airline and add a diffuser.

I'm regulating the flow to the algae scrubber, I'll call it that for now since there is no sand or rock that you might find in a typical refuge, mainly out of curiosity. However, I see your point with regards to providing a higher concentration of nutrients to promote growth, and subsequent uptake.
