An overflow will be drawing a lot of water and AIR. This will ruin your Filstar in a very short time. Overflows are intended to drain water into a sump system as has been mentioned.i realize i have the tubing and hook up to the xp3 canister already, so i will be hooking that up.
rena filstar xp3 is the full namethe way it looks now there are tubes running from those valves(?) down to a attachment that goes right onto my xp, the tubes are heavy thick rubber ones they kinda in a "y" design, will have pics later on today when i get home. What is a filstar?
Thank you to all with your information
