Air exchange is a key variable in a reef. Here, we identified another driver in carbon to feed algae.

When I shut down my 12' skimmer, I added a 3' x 4' waterfall scrubber.
When I shut down the scrubber, I added a 4' x 2" PVC air injection shaft.

Failure isn't an option It's a requirement. 660g 380inwall+280smp/surge S/L/Soft/Maxima/RBTA/Clown/Chromis/Anthias/Tang/Mandarin/Jawfish/Goby/Wrasse/D'back. DIY 12' Skimmer ActuatedSurge ConcreteScape
