Hi all,
We bought our new home last year in Austin, TX, with an approx 18,000 gallon pool (plaster).
I "took care" of the pool my self last season and it went kind if ok while only checking the chlorine and PH and shocking the pool from time to time.
I did not now much about CYA, TA and other parameters at that time. I guess I got lucky it did not turn out bad.
Intelliflo Variable pump, Pentair 420 Cartridge filters, inline Chlorine feeder and also a flow meter that I installed last year when I was trying to set up the pump properly. I have it running ~15/16 hrs a day with a flow at 30/40 gpm, around 1400 RPM
I did not take care of the pool properly this winter and discovered a nice murky water when i removed the leaf net two weeks ago.
The cartridges and the filer were also super dirty and were never changed since the pool was built in 2013, so I cleaned everything, got new cartridges and shocked the pool with a lot of chlorine powder.
The water went back to normal within a couple of days (still have algaes here and there though), however FAC and TAC are now at zero despite chlorine feeder running at max and 2 pucks in the pool.
Went to Leslie yesterday to have the water tested :
FAC : 0
TAC : 0
Calcium Hardness : 530
CYA : 120 (that's gonna be worse because I shocked the pool again just after I got back from the store...)
TA : 100
PH : 7.4
Copper : 0
Iron : 0
TDS : 1000
Phosphates : 0
So today after I learned about CYA and calcium hardness I started to drain the pool and ordered a TFT100 to have this pool back in control.
I have attached a picture of the algaes, not sure if they are black or mustard, but I need them gone as well.

Can you guys help me on the next steps here :
1 - Drain ~70/75% of the pool, skimmers are off, the filter is set on main drain only
2 - Brush those algaes every day
3 - Refill and test the water, then Slam using Poolmath. Hopefully CYA level will go back to the ~40ppm range.. I will use liquid chlorine for the Slam, however when everything will be up and running properly I am curious about the impact of using the pucks in the chlorine feeder again through the whole season. I might try and monitor the impact on the CYA and stop if it rises to high.
Am I missing something here ?
Thanks in advance for your inputs !
I will update my signature soon.
