fighting mustard algae

[PoolDoc]

will leave TA alone for now...would love to do the borate thing but want to make sure algae is really gone.

Actually, borates would help with that.

But . . .

I don't think pool leaks but we add water regularly/daily.

Sounds like a leak. You need to do a bucket test, to find out:

ok, will do test. Should pump be on overnight for the test?
thx

[PoolDoc]

Yes. Later, you may need to turn it off, to see if it leaks LESS with the pump off . . . assuming it is leaking.

ok, I'll leave it on. I sure hope we don't have a leak...
thanks

[PoolDoc]

me too.

Not able to do bucket test last night so will do tonight.

I have a glass jigger with 5 ml so measured pool water then put in K-2009 tube and tested for FC. Worked GREAT! FC = 10. I guess it might be more challenging if FC is low.

Just sent husband to Leslie's with water sample to see what test results they get. Told him NOT TO BUY anything!!! I've used sooooo much reagent this summer shocking pool at regular level then mustard algae level multiple times. Glad to find a way to test with less reagent!!!!!

Can I use OTO test when FC is back to 5?

will check back about leak.

Thanks!!!!!!

Husband just called with Leslie test results (done about 30 minutes after I tested FC):

FC = 5
TA = 70
pH = 7.4
CYA = 40
Calcium = 50
phosphates = 1000

I have never tested phosphates. Please let me know if I need to do anything...I'll check forum too.

Do you think Leslie's results are more accurate than me? I have trusted their test results in the past, just didn't use their recs.
