Have you seen an increase in macrophytes (leaved and rooted plants)?
Some rooted plants (looks like Sago pondweed) have been growing rapidly. Duckweed continues but manage with skimming and spot treat with Reward. No other chemicals or agents have been put in either ponds.
I have seen gradual changes in both ponds over time but never this dramatic. The fish are still very active and feeding. After the water cleared in the small pond I removed a lot of pondgrass (and stirred up the bottom layer in the process), I now have what almost looks like a light oil slick and lots of greenish bubbles on top.
Weather has been mostly sunny; night, 47-56 and day, 77-85 . Water temperature 68 deg.
Last night I added some microbes/enzymes and aerated well water to both ponds. We'll see what happens.
