About 7 years ago while cleaning my HOT Magnum, I knocked it over and broke the coupler that joins the intake tube. I used aquarium silicone to glue it back together, but then I set it aside and forgot about it for a couple of years. When I wanted to use it again, I was extremely disappointed because it no longer worked. The impeller was working but it wasn't sucking water into the filter. I've fiddled with it a few times over the past few years but it's basically been sitting on the floor collecting dust ever since...
Tonight I accidentally kicked it with my bare toe, and instead of getting mad, I decided to tear into it again but it still had the same very weak output. But, when I filled it with water and plugged it in with the intake tube out of the water, it pumped water out as it should. I figured something had to be blocking the intake, so I took a long rod and pushed it through the intake tube and I felt some resistance. Then a large piece of silicone dropped out. I guess when I glued the coupler back together, I used too much silicone and it bunched up inside and clogged the tube. Now it works like a champ!!
I'm very happy about this because the HOT Magnum is the best filter ever made for water polishing. I set it up on one tank at a time and move it from tank to tank for a couple of hours at a time and the water is crystal clear. Unfortunately, Marineland discontinued them about 10+ years ago, so if you ever come across one that still works, I highly suggest buying it no matter the cost.
