I’ve had my pond for 4 years and yes I’ve had my issues. And have learned a lot!! But this is new! I have like algae on top of my pond. I go to scoop it off with the skimmer and it just falls apart into the water and then comes back a while later. The water is slightly green. I have vacuumed the pond tried skimming it and so on. But the problem I’m having, is I have 3 filters hooked up to my pond. A cheap foam one in the pond going to some other ones. And my pond has been crystal clear since doing this 2 years ago!! Now I have to clean the foam filter twice a day cause it’s clogging and I cleaned the other ones. Which usually only do at the end of the season and they were bad too. What do it do to help this? I’m going away for a couple days for the 4th. And I’m having someone come to feed them. But I don’t want them to have to clean the filler too. Thank you.
