I only have 1 power head and it's a tunze 6045, which goes for around $88 at BRS. Although it is not a programmable variable flow, the flow can be adjusted manually. It is quiet and reliable and has been in use for years.
Used to run Tunzes years ago, switched to Jebao (various series of the biggest 5k+ GPH models) maybe 8 years ago and have found the reliability/price to be good. I've also started running some Sunsun powerheads over the past year or two and they've been very reliable so far. Only $8-$15 at PA, and only a few watts. I use them in constant on applications and turn off the higher flow pumps at night (I also keep on a gyre - also Jebao, also good).
Maxi-jet mods were fun Went through a bunch brands but Tunze are the best for longevity, performance and customer service is fantastic. The 6025 are good to mod if you like to tinker. I had a pile of the Jenao wp40 and giving them another shot With the ow-40. Time will tell but I can guarantee they won’t outlast the Tunze power heads that have been going for years.
Can’t go wrong with jebaos. When they stop, just soak them a few days in pump cleaner powder in RODI water. Then rinse thoroughly and they will be as good as new. I think BRS sells that pump cleaner from fauna Marin.
Jebao are best bang for the buck.
They even have wifi controlled versions now. 1/4 the price of MP10 to 40s. With as much or more control.
