impressive set up, have you thought about having one of the smaller tanks set as a moving media filter? Perhaps a planted tank you help reduce nitrates? Also with a system this size, are you running a drip system for water changes?
Looking good so far!
Amazing job so far.
I´ll be watching this closely and keep on learning for my (near) future project.
Thank you, in my experience don't wait just start the project you wont regret it. 1/2 the fun is the planning building and filling the tanks for the first time.
