Replacing liner in 24,000 gallon in ground pool in a few weeks, and I have a question about the refill. Can I refill the entire pool before I start adding chemicals, or is there a certain point when I should start the pump and begin adding chlorine? I have no idea how long the refill will take, but I am guessing at least 30 hours. This will be my 3rd summer with the BBB method, which has worked great, but I don't want to wait until pool is full if there is a chance for algae to get started. I also don't want to be do anything harsh to my new liner by putting chemicals in too early.

Thanks.

If your pool gets up to the skimmer in about a day to where you can turn-on the pump, you can just do it then. You won't see an algae outbreak in just one day. If you are really concerned about stagnant water, or the refill takes longer than expected, you can add just a little bleach (1-2 ppm) and brush it around really well if needed. But again, very little because you don't have stabilizer in there yet. Bleach with no stabilizer is more harsh to the pool.

Speaking of CYA ..... use the Poolmath calculator to know in advance how much granular stabilizer you need to add so it's in a sock and ready to soak, then add enough bleach for a day one target of about 2-3 ppm. Once the CYA is all dissolved, adjust FC according to the Chlorine/CYA Chart. Also check your pH on day 1 and adjust as well, then you're on your way. :swim: Hope that helps.

There isnt a lot of risk yet with algae forming quickly at this time of year. Its not like the water temp is 90.

If it worries you, when the pool is 1/2 full, dilute a bit of bleach in a couple of 5 gallon buckets - enough to get you up to 2 ppm, and pour it in slowly all around the perimeter. Then mix it up well with a broom, or if you have a robot, put that in there to mix it up for ya.

Can I or should I turn on the pump even before it gets to the skimmer, just being sure to keep the skimmer turned off? Letting the bottom drain do the return work, or is that not good for the pump? Maybe when it is 1/2 full?

Thanks for the replies.

If the pump stays primed when pulling from the main drain only then it should work just fine. If it looks like the pump strainer pot is filling with air then you will want to wait until the water is high enough in the skimmer. Are you able to shut off the skimmer line? If you don't have a valve to shut off the skimmer then you will be sucking air into the system through the skimmer while the pump is running.
