Morning,

Alright, I've been away from home a couple of days and finally got to retest again. I feel like I'm starting over. However, I did add in the acid and CYA before I left town.

Firstly are there better times to test the water, i.e evening or morning? here are the results.

CL 1
Ph 8.2
ALK - 290
Hardness 410
CYA <30 but improving over last test.

I added more acid and CYA this morning after I tested and will retest in a couple of hours and will post the results.

I'm using the HTH 6 way drop test since Taylors hasn't arrived yet.

Here's the other part of the equation. I was able to get the Taylor salt water test kit locally and the number is reading 7600ppm which is way to high. Intext says 3000ppm is what I should be aiming for. I'm going to drain the pool and refill which I know will now change the numbers up.

Suggestions and thanks!

If you're going to partially drain the water, go ahead and do that before you add any more CYA or acid, so you won't just dump it out with the waste water. Besides, refilling , if your tap pH is less than 8.2, will help lower that pH. And if it's not lower, then you won't waste a bunch of acid lowering it just to have it raise again when you refill the pool.

After a good amount of lower, refilling as to not go low on salt, I was finally able to get the unit to operate where it's working without a low/high salt warning going off. Added acid and CYA (sock) then let the unit operate for 2 hours like the manual suggests for my size pool.

Here are the testing results taken this morning at 7:30.

TC 5
Ph 7.2
ALK 260
Hardness 280
CYA 50

I am also using a solar cover during the daytime.

Looks good.

Just keep your pH in the 6.8 - 7.2 range, and your alkalinity will drop over time. What will happen is that some of the 'alkalinity' will leave as carbon dioxide; your pH will increase; you more acid to get back to 6.8, and it starts over. The more you splash around or 'aerate', the fast it will happen.

But, there's no hurry. You can simply maintain a lowish pH, and let it go at its own pace.

Thank you both, I read all the links before I even started messing around with the acid.

Also, I'm keeping track of my readings/use of acid CYA in a log.

...I am also using a solar cover during the daytime. Are you using it a night? The solar cover will help more to keep the heat in overnight than it will to catch heat during the day.

Unless there's someone in the pool, the solar cover is always on.

Being a smaller pool, I'm noticing evaporation (I see no leaks) of water since we've been in the 90's and my pool is in direct sunlight for all of the day.
