What to add during fill.

[Phillbo]

If lucky I'll be filling my pool this weekend. What should I be adding during the fill? I've seen people state they added Stabilizer while filling .Or should I fill it and then take a sample?

Also I understand I should use bleach to get the water up to a good chlorine level before turning on the SWG .. True ?


In ground plaster pool . About 21K gallons. SWG.

Take a sample now if you will be using your water to fill. If it isn't your water, find out where it's coming from and get a test of that. That way you will have what is needed on hand.

I believe Ben advocates starting to add chlorine when you have a foot of water in the pool, but I couldn't find a reference in a quick search.

I do plan to get a sample of the hose water i'll be filling with .

Anything ?

Do you have the test results of your fill water?

Philbo;
If you are not an owner/builder ask your builder for a printed list of startup instructions and then follow them to the letter. Otherwise you could have problems with any pool warranty your builder offers. In a worst case scenario of extreme de-lamination you could end up paying out of pocket for a plaster strip and re-do which isn't cheap. So please ask your builder.

If you are the owner builder here are the best startup instructions I could find:

Click on the link found on that page it's a pdf of a powerpoint presentation.

imfignewton gave me this link and though it wasn't specific enough for a quartz aggregate startup it maybe for plaster:

PS We are not starting our SWCG for a month we are running on sodium hypochlorite plain bleach not powdered. Next we will hold off on our heliocol for heat for at least 2 weeks although living in the Mojave with 120 degrees air temps we may run it at night for cooling.

Baseline numbers from the hose ...

chlorine - 0
p.h. - 7.8
alkalinity - 130


looks like i'll need to get some acid in as soon as it gets full . will the alkalinity come down naturaly or should I be prepared to add something to control that?
