I just installed a new cartridge filter after several years of struggling with our very old sand filter. The water filtration is really great EXCEPT...
there was an algae bloom. I got the water clear through shocking and balancing, but algae was still growing or settled on the sides and bottom of the pool. I went to vacuum the bottom and sides and shortly the jets began spitting out cloudy water. Within about half of an hour, the pool was green. I thought that I would vacuum to waste, which I used to have to do when cleaning up after a bloom. It turns out that that is not an option for this filter.
Does anyone have any ideas:
1) Is it normal to have algae sludge so fine that it gets through the filter?
2) How can I clean up without some sort of vacuum to waste option? OR
3) How to install something that will allow me to get the green out and back to a clear pool? (Could close all jets but one and stick a hose to it to drain into the yard, but that seems like a lot of work).
