I will add that, in our pond, the bog is fantastic biological filtration but over time we found we needed more mechanical filtration. Perhaps a function of our bog not working quite like it should - I don't know if we have enough settlement time to reduce fine floating debris. We also do not have a skimmer - our pond has a negative edge design.
Anyway, we purchased a box filter with six filter pads last year - so much better and easier than the quilt batting for long term use. We tried to janky up a quilt batting filter, but it was literally clogging up in hours. Too much work for this lazy ponder. The box filter could run for a week or more. It was more expensive, but it will also last forever, so it was a good one time investment for us.
Thanks!
I bought a cheap small pump (50 GPH pump), a dairy crate, and threw it in last night. Probably will have benefited from a "moderate" pump (300GPH), but this morning the batting is starting to turn green. The water is noticibly clearer.
I had box filters with pads before, I HATED them. I hated pulling them out of the pond, hated replacing or cleaning the pad, hated everything about it. I'm super lazy.
I have two 7 Gallon buckets (deeper versions of the ones at the hardware store). Both are gravity fed from pond, one off the skimmer, one off the bottom drain. At the bottom of the bucket is a pump.
The skimmer system goes to the bog.
The bottom drain goes into an Aquascape "Filter Urn" -- I cut the inlet off and rigged a 1" PVC connector with a uniseal.
I love the look of the Filter Urn spilling over, but I think I want to change the materials inside. I think I'm going to replace the pad and the ceramic discs with a series of mechanical filters that I can swap out every few months. But it's pretty, water spills over.
My bogs are also pretty. I took 3 Resin pots, and using uniseals plumbed them to be bogs with a pipe return. Then filled with pebbles and "marginals." Instead of an ugly bog, it's a pretty bog. I'm actually going to clean out the brown leaves this weekend and replace any plants that need replacing.
I also was automatically filling the pond with some well water to replace evaporation. I think this led to poor water quality. I believe that over time the filtration will handle this. So I stopped that process. I only add small amounts of water into the bogs (not directly into the pond). Water is clearing up.
I don't want to commit to needing to pull anything out of the pond. All filtration must take place outside of the pond. I can add mechanical filtration to buckets (pre pump), but nothing that requires me to dig in the pond, I just won't do it.
