HOB Refugium

[Brandoser]

Hi,

I've been reading a lot about Aquaclear 500 filters turned into refugiums, CPR brand and DIY's. I don't know which way to go? The 500 seems economical and fairly easy but wouldn't it be loud with the water dripping?? and too small for a 50gal? The CPR comes with a poor power head and DIY seems hard. Does anyone have a suggestion on what really worked well for them??

Thanks,
Brando
