Need better filtration- but concerned about current


Recommended Posts

I have a Penguin 150 on a 30 gallon tank. This is not ideal, I know, and I want to add a second filter. The problem is that my fish are all about 2 inches/5 cm long and occasionally get tossed around near where the water returns when they're not paying attention. I think another filter would bother them. Should I wait until they grow bigger to improve the filtration? Is there a way to make the resulting current gentler, but keep the good aeration?

Actually, I would switch over to an AC70. The advantage to the AC is that it has a bigger media chamber, has adjustable flow rates, and you easily baffle the output. This is not necessary easy to do on the Penguin.

Sounds good! That is the "for aquariums up to 70 gallons" 300 GPH one, correct?

Yup. The nice thing about these AquaClears is that you can adjust the flow rate. So with the AC70, you can reduce this down all the way to 150 gph :)
