    These are the pics
    red traps (this is U.stellaris as I had trouble taking a pic of the Aurea in the ponds)

    and typical red tips on Aurea

    Algae can cause pH to go up. A big bloom can make pH rise to 10.

    Thanks for sharing the pictures! Your plants look great, much better than the Utricularia I have growing outside. The red traps on stellaris look very unique.

    This is probably not the cause of the problem, but have you added any new rocks or soil to the ponds? If so, maybe they are leaching minerals into the water, although that would likely raise the hardness more.

    During the day, and then overnight by sunrise it can crash into the 3s. Adelea have you tried testing the water at different times of the day/night?

    Just know when to keep the verdict to yourself.

    While I haven't had a pond in some years, I had found that boiling peat (over the use of simply long fiber sphagnum) provided a far more stable acidic pH. Previously, there too had been swings. I would keep some peat "tea" on hand if future adjustments become necessary . . .

    PH is the same in the ponds at 6am, noon, 5pm and 10pm (6-7pm is night), I doubt algae is the problem as I can see very little and breed up and release daphnia and horn snail as needed, this has never been an issue.

    I stopped boiling my peat as it seemed to increase the algae growth rather dramatically.

    As for the red stellaris traps, it is only 1 variant of my stellaris that do this, and I think it may actually be a hybrid of stellaris and Aurea as the floats are different to typical stellaris, the flowers look like aurea on them and the plant is much thinner than typical stellaris.

    That too had originally been an issue with me; though, by running the tea through a coffee filter to remove the peat solids, there were no further algal blooms . . .

    We had some rain so I collected some, the PH of the rain was 7.3-7.4 (varied over the 2days), this is here at uni, does that point to pollution?
