Ok, so I think I have this figured out. It's pretty obvious to me that over the course of this part of my outdoor grow, the I'll need to feed. The problem is I don't want to hurt the fish or cause a massive algae bloom in my pond. I'm going to try to treat this like my reef tanks. I use a refugium that is a tank to grow micro algae and other plants such as mangroves and shit. What this does the s break down nutrients so that my water stayed clean. I'm going to make one to go after the hydro in a "marsh" seep. This should remove all extra nutrients if I can get the right turn over. Hence, imo, once dialed in, I should be able to feed pretty heavy. This isn't thrilling to me to have to do this but I think it's gonna be necessary to pull this off riu style. The fun part will be that I'm gonna make it part of my pond. I think the turtles and frogs will dig it.
