lol yeah, its getting close for closing time!
alright here are my morning numbers:
- FC = 6.5
- CC = 0.5
- CYA ~ 20 ( this one is still hard for me, so will error on the tad lower side but it was say 1/4 way between 20 and 30)
- PH = 8.0 (going with this this time as it looks like its between the 7.8 and the 8.2)
- Water is clear
I did brush this morning and noticed just a couple of faint lines around the raised portions of the pool on the bottom (like where the liner "joins" together). when I brushed they dusted up, very light. So I wonder wit these levels I am seeing if these are indications of algae or not? I will vacuum when I get home from work and see how that goes too. The pump is really really throwing nicely now from what I can see on the return line, maybe the low water level contributed to that not being as strong?
So based on this, I am going to look into lowering PH next. I am thinking if I do that then if I do need to do a SLAM, at least the PH is now lower. I am targeting 7.5 for now and see how it goes using Dry acid (pool store stuff) from what the previous owner left here.
As for CYA, right now I do have some of those pucks here that I could use, Clorox brand "Active 99" tabs, are they worth using at all since they are supposed to raise CYA too?
Clorox® PoolSpa™ | Step 2 Chlorinate Pool Products
From what I am reading on them, they are 99% trichlor.
Using the Pool Math calculator section that says "effects of adding chemicals" I am assuming an 8oz sized tab, I would see:
- Raise FC 6.1
- Raise CYA 3.7
- Lower PH 0.33
I am thinking of dropping in one of these and letting it dissolve, thoughts?
Also, I think we may be very close to the point of being able to use the pool, I have ready that you can pretty much swim in the pool up to the Shock level for chlorine, is that true?
