Just bought a foreclosure, 10k pool has been down for over a year. it has a SWG, but right now just trying to bring it back to life without it. pool is very dark brownish blackish green. can only see a few inches down. took some measurements. 0 cya so I started shocking with powder and threw some pucks in to bring it up while getting FC up (like my coke bottle puck floater?) .
TA and PH in reasonable ranges. so shocking and brushing, but can't see anything clearing up. spraying down filter. got a new cart that I'm about to change out soon. I'm worried it's so cloudy and opaque that I'm gonna have to vacuum some garbage out of the pool to waste, but this is a cart filter.
here's the pump setup picture below. am I right in this that #1 is the valve for the 2 drains, number #2 is the the skimmer.
now number 3, on a cart filter like this, if I open that valve there am I just open to waste essentially? If I configure the other valuves to skimmer only and connect vacuum and open valve 3, am I essentially pumping to waste so I can vacuum some heay muck out?
I have an external pump available to me that I was planning on using with a filter bag and just vacuuming with the return hose going back into the pool through the filter bag (kinda like a slime bag) to get a lot of this debris out after I shock for a few days, but then i was looking at this piping and can I just vacuum with the valves set to skimmer only and open that PVC valve labeled 3 in the pic and run a hose back to the pool with a filter bag without using the external setup?
