New owner of a pool that just recently turned green

With your CYA near 100 and your CH above 600 ppm, drain the pool. The only caveat is if those are metal stains. Then you should treat those prior to draining. Drain it completely. Refill.

ok, so I performed the dilution test by doing the following:

-fill bottle to 7.5ml with pool water
-added tap water to the bottle until 15ml (not sure if upper mark meant 15 or 30ml)
-mixed
-dumped water back to 7.5ml
-added R0013 to the bottle back to 15ml
-mixed
-result = between 30 and 40 but closer to 40, so 80 CYA

I decided to do the test via normal process and the result was between 80-90.

I hesitate draining and then refilling the pool mainly because I'm from Los Angeles and the city I'm moving from are strict about water usable. I'm not yet sure if it's the same case here, which I think will likely be the same.

BUT also, I don't know much about the process of draining the pool, along with the filter/pump operation, aside from turning it on. Figured I'd tackle the algae issue first before deep diving into the pool equipment, especially since I'm still partly renovating and not fully moved in yet.

You use a submersible pump to drain the pool. Place the effluent hose in your sewer clean out.

You will have scale next summer as your CH will rise above 800 ppm due to evaporation.
