How much stabilizer do I need?

[ChrissyInOregon]

5061 gallon Intex. Planning on doing the BBB method (used BBB last year with a smaller pool) and may add a SWCG. How much stabilizer should I add? Is the hth brand suitable? I'm attaching a picture of what I have available locally.

[Watermom]

I think that is ok but can't read the percentages of cya and inert from the pic.

[PoolDoc]

I can read them -- it's fine. You can use that product.

Just remember that that form is VERY slow to dissolve. If you add it via the filter, leave your pump on continuously for 4 days. Otherwise, do like Watermom and hang it in an old athletic sock near a return.

We decided to bite the bullet and buy the SWCG tonight. What is the optimum CYA level for use with one of those?

[PoolDoc]

High-ish. I haven't read the Intex manual -- but you can find it here: http://www.intexcorp.com/index.php/manual-video/

Remember -- do NOT use the SWCG to start up or shock, etc. Just for routine chlorination!

Also, disconnect the wires to the copper electrodes, unless 'green hair' is not a threat to your family.

Can you recommend a way to go about introducing the CYA, start up chlorine, etc? The kids want to get in it tomorrow afternoon. Not sure how long they'll stay in it, since the water coming out of the hose is 66 degrees. How do you keep chlorine in the pool while the CYA is dissolving?

[PoolDoc]

Dichlor => http://pool9.net/ssr/

For every 10 ppm of chlorine, dichlor adds 9 ppm of stabilizer. If you can get a 24 pack at Sams Club that would be idea. They are one of the few stores reliably selling un-diluted dichlor. Otherwise, you may have to get it from Amazon. You can check Lowes, Home Depot, and Ace -- dichlor that shows 56% or higher available chlorine (NOT: 56% dichlor!!) is the good stuff.

We have no Sams Club stores in Oregon.

I already bought the hth brand stabilizer. I will plan on doing the stabilizer in the sock tonight, and adding bleach. Unless someone thinks that is the wrong way to go.

[PoolDoc]

That'll work.

[Watermom]

Since it will take awhile for the stabilizer to dissolve, you may find that you need to add bleach a couple of times per day for the first week or so. After that, you'll be able to go to testing and dosing in the evening only.

[ChrissyInOregon]

The SWCG manual says to use 1.3lbs of CYA for 5061 gallons, but doesn't say what level CYA that brings it to.

[PoolDoc]

Surprisingly, 30 ppm.

I added stabilizer at setup but only the minimum amount and use bleach with a few 1 inch hth ( I got them free) tabs when I know pool will be used heavily and it appears to be working for me. I am not losing that much now I did once a week ago but it has stabilized now. I know nothing about the SWG
