Help with opening up a !0,100 gal AGP

[PoolDoc]

Depends on what's in the "regular shock packages".

You've got a problem, however. If you fully dissolved the 3# of stabilizer, you should now have a CYA level around 40 ppm. If you use much trichlor, your level will continue to climb.

I'd recommend using plain 6% household bleach to shock - that will not add CYA. A 96oz jug of 6% bleach will add about 5 ppm of chlorine to your pool.

I did not put any stabilizer in yet because I was going to try to get the dichlor. I was just putting in 6% bleach so far. I went out and found some "4 in 1 shock plus" (made by aqua chem) and it states: active ingredient of Sodium dichloro-triazinetrione 58.2%, other ingredients 41.8%. A 24 pack box was similar in price as to what your recommendation was (I do not have a Sam's near me). What do you think of using that? The label also states: creates sparkling water, for all pool surfaces, reduces chlorine odor, does not increase ph. Is this similar to what you recommended?

Well, I just called the manufacturer and have bad news. I asked if the product has stabilizer and was told that it does, in fact contain it. That was good, but I asked about the 41.8% of "other ingredients" and was told that there are clarifiers, filter aids, and buffers....all things that you do not recommend. Unless you tell me otherwise, I am going to return this and then use the stabilizer that I already purchased (product of china...ugh!!!)...along with doses of 6% bleach. How does that sound?

Yeah, that's why Pooldoc recommends the Sam's dichlor--we know exactly what's in it and what it will do to your pool water. We can't say the same about the generic clarifiers, filter aids, buffers, etc--who knows what all that is, and what it'll do?

I would return it, and go with your plan of adding straight CYA along withe bleach for the chlorine. By the way, when you get the 3" tabs, make sure you check the ingredient label for copper. Many chem manufacturers are adding copper to the pucks so they can re-label them as "dual acting" and raise the prices, but you don't want copper in your water because that's what stains things green (hair, nails, pool liners, etc.). Also, keep in mind that even if they don't contain copper, they DO contain CYA, so keep a really close eye on your CYA levels if you decide to use them. In fact, if you plan to use them, you might want to only add 1/2 the dose of granular CYA and just allow the puck use to raise the CYA the rest of the way.

Ok, it is CYA and 6% for me, at present. I will return everything else. I will look at the label on the bucket of pucks when it arrives...I may just return that as well. The good news is that the pool is up and running!

The good news is that the pool is up and running!

......and that's the goal!! Good job!!
