New Pool CYA at 90... Do I drain or wait?

[kdiamond]

Pool is over a month old and I have adopted the BBB method and turned off the chlorinator.

Test results from today with Taylor k-2006 kit

FC 3.2
CC .2
TA 90
ph 7.6
Hardness 280
CA- 90
Borates 34

I added bleach to raise the FC to 7 this evening. With this late in the season should I drain to get CYA down or just keep the FC at proper levels and see if CYA comes down with use and rain?

I would say if you water is clear, wait to drain and just make sure you FC never ever drops below 7 ppm and you should be fine. That will require you to shoot for a higher FC when you dose. I would try shooting for 9-10 ppm FC.

How long till you close or if at all ? You could drain some to get it down if your going to be using it alot. It's your call.

Your FC level at 7 ppm is at the min for a CYA of 90. Your FC should be at least 10 ppm so you don't fall below your min of 7 ppm.

Yes, water is clear. Since I live in Texas, we will use it thru Oct. I planned on keeping it up all year unless there is a better way. I will keep FC between 9-10. Should I increase Borates to 50?

What is your current borate level?

I probably would wait until after you do a drain/refill to reduce cya.

Just one more thing.... Stay on top of your FC levels cause if you get an algae bloom its gonna take a boatload of bleach to clear at a CYA of 90.

linen.. borate is at 34

I would leave it until you drain so you don't waste your chems.

 

[kdiamond]

Ok, I plan to leave it and drain later.

turned off the chlorinator.

If there are tabs in the chlorinator, I would recommend allowing them to be used up or remove them. Turning off the chlorinator only isolates the tabs in the feeder with water. They continue to dissolve, creating a very concentrated chlorine solution that can damage the chlorinator and can be dangerous when the chlorinator is opened.

Thanks James. I did not think about that.

Wait to drain, keep up your chlorine level above 7ppm. Pucks will do that. LOL
