I have mentioned to my DH that totally gutting the biowell several times a year to clear out the horrible algae might not be the best idea but he says he only lightly sprays the bags with the rock in them and also the two large mesh thingies (technical term lol). So he doesn't feel he is totally disrupting the bacteria. And we do have a fierce algae problem, especially string algae in the falls areas on the flat zones. I treat regularly with Algaway 5.4 from MicrobLift and it kills the algae but it still has to be filtered (mechanical) out by the skimmer. Tons still ends up in the biowell. I don't believe that the UV lights are functioning. Well, actually the 55W isn't even hooked up as we have tried unsuccessfully three times to get a new lamp up here and they arrive broken. He is thinking of buying three pressure filters (we have one now with 25W UV) and daisy chaining them. Seems rather extreme but he is okay with it.
Our water is clear and lovely right now. We have had a week of clouds and rain which has slowed down the algae and the pond looks great. Like a pond should lined with algae but not intrusive stuff.
