I wouldn't call it wastewater per say. I just have duck poop instead of fish poop and fish food as my biological matter. My Ammonia levels have subsided, along with Nitrites, and the Nitrates are stable. Since I use the pond water for watering, the Nitrates get diluted out, but there ARE plants in my pond that also feed on it (and the normal algae that builds up in a low flowing pond).
The UV clarifier probably won't kill all the bacteria since it's not classified as a UV Sterilizer. And, admittedly, ponds are relatively new for me, but I have always had aquariums, including saltwater reef systems and fresh water planted system.
I originally thought the duck's recycled food would be too much, but the water is actually clear as of today to the bottom. I give major credit to the dosing of beneficial bacteria to make sure there is enough present while they establish themselves throughout the pond and it's upflow filter.
I still have to nuke the algae bits that are still in the water column, but the filter socks have mopped most of it up. But I would tell past me to invest in a larget skimmer/filter, even if the flow isn't needed. I want more volume for mechanical filtration to keep the water clearer. I'm currently still rinsing the filter pads out every 2 days and that's not ideal, so hopefully the UV Clarifier cleans up those large diatoms and gives my pads a break! We'll see!
Thanks everyone for the advice and compliments
