it’s a very deep rabbit hole my friend. I spent hours planning this out. I have a 25 gal lagoon aio that almost got de-aio’d and turned into like a mantis macro algae display refugium. The two ways I was thinking was either adding a second small return pump to feed it and then have the overflow just go into the skimmer chamber. Was going to see if I could run it low and slow and if my main pump went offline see if I could have Hydros kick up the speed a little just in case. Have had a check valve fail on me so could be more peace of mind. Lazy was to just manifold it off the return.
