New pool test results...

[FordPrefect]

Hello,

We received our test kit and these are the first numbers we got:

FC - 7 ppm
CC - 0.5 ppm
pH - 7.2
T/A - 370
CYA 35

The water is pretty clear, we can see the bottom, but it is slightly cloudy which I am guessing is a result of the high T/A.

We used the trichlor pucks that came with the pool and Pool Magnet from the pool store to get rid of the iron in our water. We now want to go BBB.

The pool calculator seems to indicate that we need to aerate the water to reduce our T/A. It's pouring rain right now, should we pull back the solar cover?

Thanks in advance.

Leave it off, that's how the aeration works.

It'll go faster if you point your return all the way up so that it breaks the water's surface.

 

[frustratedpoolmom]

I thought your post said "put back".

Yes, take it off!!! LOL

 

[FordPrefect]

Cover is off and the return is pointed up. Thanks!

Good. When the rain stops, keep an eye on your FC level if you see it drop or the cloudiness turn a greenish tint then dump some more bleach in there because it could be the start of algea. Be sure to run your filter non-stop till the cloudiness goes away.

Now go put on dry clothes....LOL

Will do, the last thing we want now is an algae bloom.

The lazy, Friday-off pot of coffee has already warmed me up

The rain is still falling, the PH is now 7.5, FC is 6 ppm and the T/A has dropped to 350

The pool calculator is asking for 6 liters of muriatic acid. We have four liters (should have bought more, but who knew?)
It seems like a lot, and we would like some confirmation before pouring it in. Does this make sense?

Use Jasons Pool Calculator http://www.poolcalculator.com/ to to determine how much muratic acid to add to lower your PH to 7.0-7.2 this will reduce your TA and then aereate to bring the PH back up to 7.4-7.6

Because you have such high TA you will have to do this process a few times , so yes go buy some acid

When TA is really high it takes huge amounts of acid to lower the PH. I get just over 6 liters. If you feel at all uncomfortable adding that much at once just add one or two liters at a time, let it mix for half an hour and then test the water to see where that got you.

After following the advice on this forum and via the Pool Calculator I am happy to say that our water is clear and sparkling!
As of 9:30 last night:
T/A - 130
PH - 7.2
Cl - 4 - 5
We aerated all night again and I am assuming that this morning our PH will be closer to 7.5 and all will be well with our pool.

Now all we need is for a Manitoba summer to finally replace this Manitoba winter and we will be swimming

Thanks for all your help, both in this thread and everywhere else.

Congratulations!
