Starting from scratch (new water)

[jilted]

will do... I'm going to jump in later and feel the floor but the wall was not slimy.

The FC test was approx 14 hours after dosing so I will check again this evening and again in the morning.

the first 6 lbs of CYA has pretty much dissolved so I'm about to go add the 3rd 3lb container which should still have me at the lower end of my recommended level but since I am running pump 24/7 right now anyway I don't want to waste any time getting cya up to a respectable level

FC was 7.5 ppm last night and 7.0 ppm this morning. I haven't powered up the SWCG yet but I guess it's time. Salt test last night shows 3600 ppm. I was waiting to start it up to get an idea how fast the FC is burning off but ever since I added chems (2 days ago) it's been cloudy and cool here.

I know I need to continue adding CYA but my salt calculation was 18 bags to get to 3500 ppm and I am at 3600 with 15 bags. I am still waiting on my new CYA reagent to test. I don't want to over stabilize!

thanks

Just checking in. Water has been pretty good.

FC has been easy to manage so far.
Having trouble getting pH to level off I guess the SWCG is keeping it increasing. Also the alkalinity never drops when adjusting pH.

Test today:
FC: 5.5 ppm
CYA: ~50 ppm
pH: close to 8
Alkalinity: 140 ppm

I've dosed muriatic acid a few times according to the book in the taylor test kit. 2 drops bring the test in line. The ph does come down after this but rises again in a couple days. The alkalinity stays 140.

I've been running my pump 18 hours a day which should be enough to circulate the whole pool twice. The SWCG was running at 100% but I have reduced it to 80% to see if thats enough to keep the FC stable.

Any input on my pH/alkalinity situation?

Thanks!

I'd target 7.0 - 7.2 for pH and try to keep it there until the TA is where you want it.
