I am in process of designing and laying out my new scaled up AP system. In my previous systems, I never used any sort of biofilter (other than beds) or solid separator. Since I am planning to have several raft tables in this system, I know I need my water to be extra clean. This being my first venture into filters I wanted to run this setup by some folks to see if I am on the right path.

My plan is to flow from the Fish Tank into a 55 Gallon Swirl Filter, then into a 55 Gallon BioFilter containing scrubbing pads and finally into 55 Gallon Moving Filter Bed containing K1 Media. From there the water will flow to the raft tables and various grow beds. All beds will drain into an underground sump which will pump back into the FT.

Just curious if I’ve got the path right?
