We just moved into a house with a pool a couple of weeks ago. I am still learning terminology, so if anything is wrong, please feel free to correct me.
I believe the pool setup/specs are:
When we arrived at the house, there was some remnant of previous owner (PO) test equipment, and an initial limited test found:
FC: 0
CYA: >>>100 (maybe around 200?).
I believe the previous owner primarily used stabilized pucks to chlorinate the water and it has not been drained for 1.5 years, so that probably makes sense. The water was starting to get pretty green by the time we moved in (house was unoccupied for a couple of weeks while we had some work done). I went ahead and ordered the Taylor K-2006C test kit.
In the mean-time, we used a very low speed submersible pump to start draining/refill to lower the CYA levels. Because the pool-pump schedule is automated, I turned off power to it at the breaker box while draining. Because we just moved in, we started draining at very low speed to see what our sewer clean can handle. It took about 3-4 days to lower the to about 1/2 filled. We filled it back full yesterday and got the following test results:
FC: 0
TA: 180
CYA: 100
PH: 8.4? (a little above what the scale read, this is an estimate)
CH: 420
The CYA has come down since our initial move-in test, but, we are now starting with another half drain/refill to hopefully reach a more reasonable number.
While this has been ongoing over the course of a couple weeks now, the water is VERY green now. I have not been adding chemicals for the last week or two, knowing we would be draining and refilling.
My nominal plan is
I believe the pool setup/specs are:
- cartridge filter
- multi-speed pump
- waterfall
- ~15,000 gallons.

My nominal plan is
- Refill
- Run pool-pump at high speed for a few hours (with how green the water is, do I need to get a new filter right away?)
- Take CYA levels -> if within reason, proceed. If not, partial drain/refill again
- Take PH, add muriatic acid to bring down to ~7.5
- Start SLAM
