Im not too excited about the MP60s. while they have plenty of rpms and do push a bit of water the flow is fairly narrow, at any setting. Ive been thinking of trying out 2 of the large Gyres. and perhaps not use the MP60s. They are a bit noisy although I don't have the most recent "quieter" versions.
Would I do it again.... no... however our options are limited and so I probable chose the best option at the time. My system is in the basement so while noise isn't a critical factor I was still disappointed. Theres a few thing about the MPs that I am not excited about. The company wants you to "rely" upon a sticky tab included with it to ensure it does fall off or drop... yes, a $.02 sticky tab for a $675 pump. second, the magnet doesnt hold the pump on as well as I would like and makes me uncomfortable. The cord is too short for those of use with large tanks and lengthening it voids warranty unless you send them the whole thing and have them do it (I have one extended unit).
Some people seem to really enjoy these pumps, me not so much. Throughout the build Ive tried to select the best or at lest close to best of products available and with the mindset of keeping the electrical bill reasonable. Populating my tank with 4 or more MP60s seems like an unnecessary expense both upfront and in operating costs. If I can use 2 gyres to better cover the flow of the whole tank with similar costs then I will ultimately end up going this route.
Another item I would change is I would have opted for multiple submersible return pumps rather than 1 single reeflo hammerhead....its the noisiest thing in the whole system... however it is the most efficient for my setup.
