Low pH, Hardness, Alk, where do I start?

[Watermom]

The OTO tester can also be used to measure bromine and thus has a bromine column on it. I'm assuming that when you say that your chlorine is 3-6, you mean 3 and the 6 is in the bromine column. (Just ignore that.)

Go ahead and add some more bleach to get back up to about 6ppm --- assuming that I am right in my assumption above.

Yes to your question about another dose of Borax and baking soda.

No need to test calcium hardness. CH is only an issue in a vinyl or soft-sided pool if it is too high. Yours is fine.

Do you have an HTH 6-way drops kit or an OTO kit? Just wondering how you got your CYA reading.

Yes, I'm using the HTH 6-way test kit.

You're right about the chlorine and bromine columns. I had not noticed that before, and was thinking it was a chlorine reading of between 3-6ppm, when actually the chlorine is 3ppm.

I got the CYA reading with the HTH 6-way kit. I purchased the kit last year and it contains two CYA tests. I used the second one this year.

Chrissy and all,

I am 1st time poster. I read your post about the low ph. I have had the same problem for 2 years. I have been dumping baking soda with no movement on the scale. Went get the Borax Mule 20 and put 12 boxes over 3 days. ph is at 7.4. Thanks to all.

Any help will be greatly appreciated. BayouMac
