    I know a uv filter or diatom filter will work but I am curious as to why ponds/lakes clear up but not aquariums? Adult greenwater uses the same nutrients as plants but what is different in the wild vs aquariums that make it so hard to treat? There must be another way to fight gw without uv or diatom filters. Anyone????

    Temp, nutrient issues, other herbivores(daphnia etc), there are many variables that we cannot do as easily.

    If you plant lots of Rye around the pond, it'll lso not get algae(mats or GW).

    The green water in some bodies of water really never clear up. You can see this in farm ponds that get a lot of NO3 and PO4. Some larger lakes get greenish in the summer, but that seems to go away as the season progresses.

    Green water in aquaria will also go away by itself, eventually, when it runs short of food. I once accidentally overdosed Flourish by a factor of 10. Mild green water appeared the next day and lasted for about 2 weeks, then went away to stay. (That was also in a newly set up tank, and that could have also been the cause of green water, but I doubt it.)
