Bought a house with an inground grecian pool about 20,000gal. Removed cover on saturday and found a lot of green algae on the bottom and halfway up walls. the water itself was clear.
local store suggested 15gal chlorine and revive. I skimmed the top yesterday.
I'm ready to vacuum but don't know that there is a waste output in the plumbing.
I'm fearful if i vacuum when filter is in discharge it'll clog up the filter?
There is a hose bib above the pump, can't imagine that is the waste output?
Help me understand where I can vacuum to waste in this system.
Also the previous owner has the main drain closed. Can I keep this closed to prime and vac?
