Looking for powerhead ideas. In my last tank I used Hydor Koralia. Hated them. After a while they began clicking and eventually broke apart. In this tank, I chose to use a pair of Tunze 6020’s and now one is clicking and the other is just buzzing. I am using a Hydor SmartWave. Any input is appreciated. Pic of said current tank. With the powerheads behind the fake wall, they must alternate otherwise they starve each other and there is no flow. Due to cost involved, 2 nano AC pumps are preferred over anything DC at this time.
