Danner Manufacturing, Inc., Supreme Hydro-Mag, 2400 GPH Recirculating Water Pump, 40140

Very happy. Works exactly as expected for my fish pond.I’ve purchased it before and was very satisfied, rebuilding the old one for a backup.

Replaced same pump that had been in use for 10 yrs.

Plastic impeller. Really? I have two filters in an aquaponics system and this thing still self destructed. The other thing they don’t tell you is once their super-sensitive impeller breaks, the resulting imbalance destroys the pump housing. Yes, go ahead and buy the $60 replacement impeller. It won’t do you any good. This is after the first pump just stopped working for no reason. Had no choice but to buy a THIRD one. Yea, it stopped working a week after installation. Took the impeller out. Clean and undamaged. It just stopped running just like the first one. Unfortunately this time it cost me $500 worth of water and killed all the plants. Spent two days trying to save the fish waiting on FOURTH pump. I thought a mag pump would be a great idea but the technology just isn’t there. Going back to a standard pump ASAP. Stay away from these pumps! They can not tolerate anything but pure water, and you won’t find that in the real world of fish ponds and hydroponics

This is my second Danner pump for my Koi pond. 2 year life span tops. Wouldn't buy again.

Worked on my fountain like a charm
