Just Embarking on the BBB Method - Help Needed

[tundraSQ]

Thanks for your advice. Unfortunately I've tried brushing it off and it's not coming off. Hopefully when I get the pH balanced that might help?

I looked at Michael's formula but it asks for liters (I guess since it has an L) not gal and it want's to know another fact that I can't remember at the moment that I never seem to know either.

If I'm using the BBB method, where do I get the CYA? At a pool store? And do I ask for cyanuric acid or some brand name?

Thanks.

ask for stabilizer (so as not to confuse the counter person)...but read the label to make sure it contains CYA. you wil want to start with 3 lbs.

To change from liter to gallon on the Bleach Calculator , click on settings, plug in default volume and bleach value, click imperial, save and close

The stains that are there are probably from the algae and are organic. As your water circulates with the high chlorine the stains should fade. If they don't, let us know.

Thank god! I have been googling conversions for everything, and was about to look for a measuring cup in metric.

Thanks for the hints for using the bleach calc in gallons!

Today the water is sparkling clear!! but the walls are still green/brown.

About an hour ago my #s were:

FC - 4.5 (down from 11.5 yesterday. Wow, it goes fast!)
CC - 0
TC - 4.5
pH - 7.5 (up from 6.8 yesterday after adding 4#, 76 oz of 20 Mule Team)
ALK - 90 (up from 80 yesterday)
Cal - 140 (up from 120 on 6/7)

I know I need stabilizer. Tundra you said start with 3 #s. That still right?

Should I put that in before adding more Chlorine or after?

You guys are life savers - or at least sanity savers.

You will need some stabilizer, but in a 16,000 gallon pool, I'd start with 4 lbs. which should get you around 30ppm. You may decide later to bump it up to 40 or 50, but 30 is a good starting place.

Try and sustain your shock level for your chlorine by testing 2 or even 3(better!) times a day and each time shock it back up. If you let the cl level yo-yo up and down, you'll never clear the pool.

However, I wouldn't add it just yet. I would wait until you take care of the algae problem.

Thanks Watermom,

Shock level - is that around 15ppm? I seem to recall reading that somewhere on the forum.

There is so much info on the forum that my brain gets full and then I can't find what I need later.

You said "I would wait until you take care of the algae problem." Are you saying (I hope) that by keeping the CL up to shock levels the junk on the pool sides should disappear or are you saying that even though the water is clear I still have an algae problem?

For a pool with a cya reading of 0, shock would be up to 10ppm. Just now reread more carefully through this thread. I agree with Marie, that hopefully with a few more days of high cl, the stains on the wall will fade. If it were my pool, I'd keep the cl around 10 for a few days longer and then I'd go ahead and add the stabilizer.
