Opening pool

[Russo221]

Ok so I opened the pool today and surprisingly clear water...so excited...that being said just filling the pool to appropriate level so I can run the pool and start testing cya level. I do have a question I read the opening your winterized pool on the site.....with the pool being clear do I proceed with slamming procedure? And if so it doesn't really say for how long I have to slam it for

Wow! That water looks remarkable.....no need to SLAM.

Simply run your pump for a few hours to circulate water and then take a full battery of tests, Please post them right to this thread and we'll get you balanced and on your way!

Nice closing last year.....that's why your water is so perfect looking now.

 

[Russo221]

Thank you...will do

There ought to be a law preventing pool openings like yours! Amazing!

 

[Fingaling]

Wow.

After filling, testing, ph balancing, and brushing real good I'd probably still bring it to shock level once and then do an overnight chlorine loss test. Just to make sure nothing happens to that beautiful water you have.

 

[Fingaling]

And then I'd tell everyone exactly what you did to close !

 

[Russo221]

Ok so I got testing results

CYA 55
PH 7.5
TA 110

 

[Russo221]

With that CYA level I'm assuming shock level would be about 22?

 

[jaduck]

Round the CYA up to 60 and use a FC of 24...

 

[Russo221]

You know I was thinking that, I think I'm just gonna shock it once and then bring it down to normal level and then maintain

 

[Russo221]

Ok I have a question, I know the rule of thumb with a solar cover is you put it on at night add take it off in the morning....but I left it on this morning cause it's gonna be raining and dreary all day today......is it ok to leave solar covers on thru out the whole day?

 

[Fingaling]

You can leave the cover on all the time except while swimming and 15-30 minutes after adding chemicals. In fact it's better for the cover, since it stays cool, and will save you chlorine.

 

[Russo221]

Upon having a really good pool opening last weekend we have had 2 or 3 days of straight rain this days....is that grounds for re testing the cya again or it shouldn't do much difference?

 

[Fingaling]

Did you have to pump any water out? If not, all your cya is still in, although it may be slightly diluted. In an average 4 foot deep pool, your cya will drop by 1-2 for every inch of water added. Not al really anything to worry about unless you got some really heavy rain. As the excess water evaporates, your cya will rise back up (unless you pumped it out)

 

[Russo221]

So far I didn't touch anything yet since I can't do anything with working 12 hour days during the week, if I have to take water out I will do that on the weekend then prolly re test it

 

[Fingaling]

It probably won't be enough that I would worry about adding more at the moment. I usually add cya to the highest recommended level and with refills, rains, and backwashing, it usually takes it down only a little throughout the whole season. I wouldn't worry about retesting quite yet. You'll quickly run out of the reagent if you test it after every rainstorm.

Again, you only lose maybe 1 ppm for every inch of rain. Given the sensitivity of the test, you likely won't have a measurable difference.

 

[Russo221]

Actually losing some wouldn't be that bad, I'm at 60 now my target should be 50 but I'm not gonna go crazy with the 60. The 60 is still fine lol
