Hey guys so after researching a lot of these builds, it appears that most of these DiY filters are pretty similar to bioball trickle filters in aquariums? Water is forced through an area holding media with a large amount of surface area for bacteria to grow on? I was thinking a smaller version for my pond might be nice, there's been a HUGE boom in hair algae over the last couple days, like I didn't even realize the stuff could grow so fast, so I'm going to try and add a filter. Right now the bioload is three small Koi and two adult Comets, and I have a feeling a lot of the food is going to waste as they're still hidden most of the time, in fact after owning them for a couple weeks today I finally saw them all out at once, and of course as soon as I moved closer to feed them, they darted back into debris (which I've been vacuming out but the shop vac I'm using doesn't have a whole lot of power).
Anyways, that's kind of a backround on my pond, what would you guys suggest?
