After 18 years my Sac Koi Advantage is going bye bye. It got impacted, blew out the internal plumbing and the multiport valve. Unfortunately we put our filter system on a concrete pad and built the pump house around the filter. So….tight quarters prevented us from repairing it. Lol, we had to cut the old filter as it was too big for the doorway. Replaced it with a AlphaNano 4.5. Do any of you own one of these? Will clean up the spilled media and paint the plumbing so it won’t look so ugly.
