Can anyone recommend a good powerhead or circulation pump for a 12 gallon long? I'm not getting sufficient flow on one end of the tank. I'm looking for something adjustable and quiet.
I've tried a Hydor Koralia 240, but it was way too much flow for my betta and would kick up substrate if I aimed it down at the HC, which is where I'm trying to direct the flow.
I just replaced the Koralia with a Hydor Pico Evo-Mag 180, which is adjustable and puts out the perfect amount of flow, but it hums quite loudly.
