I wish I could upload a video.
Under tank sump with refugium, draining to the basement through a 55 gallon drum with exactly 200lbs of Florida Live Rubble Rock and backup into the 125gallon display. With a 20 gallon frag tank all integrated into one centralized system.
Current project:
Moving complete equipment work in progress. Need to get all the apex stuff mounted above my frag tank that is plumbed into the same 55 gallon refugium.
