Spring Opening Questions

Let's keep the chlorine below 5, till the copper is gone.

Low pH is hard on liners. Don't over do it, but do add borax till you reach 7.0. (Not higher, till the copper is gone!)

Ok - I'll do just 1 gallon of bleach then until the copper test clear. And 1 box of borax every 4hrs until I get to 7.0.

Thanks!

By the way, what's the PF:5 for in my signature?

[PoolDoc]

PF is "Pool Factor", some thing I've used privately for years, and in my local business, but not here. It's just a ratio between your pool and a pool with 1 million pounds of water.

So . . . if you add 1 pound of something that's 100% concentration, like CYA or chlorine gas, you get a 1 ppm increase of that something (CYA or chlorine). On your pool, since it's about 1/5 the size of a million pound pool, you get a 5 ppm increase.

The calculation works like this:

Say you want to know how much a box (4.75 lbs) of borax will increase your borate level. For complicated reasons, pure borax has an effective borate concentration of 11%. So this is the calculation for YOUR pool: 4.75 x 0.11 x 5 = 2.6. SO, each box of borax will add about 2.5 ppm borates to your pool; to reach a 50 ppm level (effective algistatically) you'd need 20 boxes.

Anyhow, having the PF in signatures allows me to more quickly and accurately calculate doses.

Thanks for the explanation

Went home at lunch and levels were pretty much the same CL 5.0 pH 6.8 (barely) "ions" .5 But the pool color was much lighter and more blue looking now but still very cloudy - still can barely see the bottom or sides. Added 1 box of Borax and will re-check levels when I get home.

On a side note NO wal-marts in my area have a 6 way test kit. They said there was a walmart within 50miles but I didn't even recognize the name of the town and not even site-to-store shipping. So I'm going to check with Lowe's, k-mart, etc. We're paycheck to paycheck kind of people so I may not be able to order the K-2006 kit until the end of the month.

Well today is my day that I can put a little more attention to the pool. pH is still testing too low so I'll spend the day trying to get it up. Copper still too high so I'll keep doing 1.42 gallons of bleach a.m. and p.m. I'm starting to be able to see the bottom a little bit so I'm going to vacuum today and brush the sides again. Anything different I need to do?

You need to get the pH above 7.0!
