27K gallon pool with slippery sides

[southjerseypool]

First I'm a new pool owner. I had the same slipperiness problem now I have spots of darker algae I guess. Can I do the same? I have a 27,000 IGL pool.

We often recommend bleach, because it tends not to mess other things up, regardless of pool chemistry. One exception: if your pool has copper in it, from algaecides, an ionizer, or a corroding heater, you have to avoid high levels of chlorine, regardless of type.

Later, when we know more about a user's pool, we may recommend other forms of chlorine.

On your pool, you can safely add 2 gallons of PLAIN 8.25% household bleach each evening. Get an OTO / phenol red kit (yellow / red drops) and report results. But keep on with the bleach, till you know more.

Order a Taylor K2006 test kit from Amazon (link in my blue signature block); you WILL need it. But get the OTO kit locally; you need it now. Read the Best Guess page in my signature too.

But . . . add the 2 gallons each evening -- that will keep you out of trouble, till you know more.

I received the taylor kit got it from amazon from your link. I tested the FC was 6 ppm PH was 7.8. I have a SWCG the pool is a little cloudy not to bad but still slippery

But, what as the CYA level?

That is critical -- read the Best Guess page, linked above in my blue signature block. It explains why it's so important to know your CYA level, AND what to do, when you know it.

Meanwhile, use bleach to raise your chlorine level to 10 ppm or a little higher. (Once you know your CYA level, we'll have a better idea.) And, use either muriatic acid or pH Minus (granular sodium bisulfate) to lower your pH to 7.4 - 7.6.

BRUSH your pool, once you get the chlorine up, and the pH down.

CYA is 10

[PoolDoc]

Really? Are you 'guesstimating' that? (There's no marking for "10" on the K2006).

If that is so, you need to be using dichlor to chlorinate. The fact that there WAS 6 ppm FC when you tested, doesn't mean that it won't be ZERO an hour later, if the sun comes out!

The SS recipe page (link in my blue signature block) will cover much of the info you need.
