I'm guessing if there's a reef club in the area, there are also a bunch of pond people. Anyone know where the lurk on the 'net? I have a small (150 gallon) pond by my front door. I just re-setup my filter for this year, and is yielding terrible results. I have all from from a QO3000 going through a 5 gallon bucket of bioballs. I was hoping the bioballs would outcompete the algae, but no dice. What's next? My current WAF (Wife Acceptance Factor) is fairly low for major changes. Due to other recent unexpected costs, my pond budget was nearly drained, so DIY cheap/free fixes are best. Thanks!
