Drain and refill 33,000 gallon gunite pool

[Watermom]

There is no way with this being a freshly filled pool that you could have used enough pucks yet to have CYA that high. Did you add some CYA separately and if so, how much.

Since you bought the K-2005, if you pick up the K-1515 you'll have the same components as the K-2006. The K-1515 is the part that allows you to test high chlorine levels. Check the Amazon link in my signature.

Tested again this morning. I now see what I was doing wrong.

FC 5
TC 5
CC 0
ph 8.0
TA 130
CH 90
CYA 0

What do I add now?

Thanks!

Also, my drain is abandoned. How many hours a day should I run the pump?

You will not keep that cl level at 5 for long with no CYA. Check the cl at least morning and evening and afternoon if you can and add more bleach so your cl doesn't drop to zero. You'll have to dose it frequently with bleach until you get some CYA in there.

Are you going to continue to use the trichlor pucks? If so, here is what I would do. I would go ahead and buy some stabilizer and add enough to get the CYA reading to about 20. Then, you can use the pucks awhile and build the CYA up to about 50. After that, no more pucks and no dichlor shock either or your CYA will get too high.

The other option is to not use the pucks and just add some CYA separately and go ahead and add enough to get to about 40. We also shoot a little low. It is easier to add a little more later than it is to remove it when there is too much. Either option will work.

You can just use the tabs and not add any CYA but the only issue with that is that it will take some time to build the CYA up and until you have much in there, you'll have a hard time keeping chlorine in the pool especially on a hot, sunny day.

To add CYA you can either pour it slowly into the skimmer while the pump is running and then let your pump run 24/7 for at least 4 or 5 days to give it time to dissolve in the filter. Or you can put some in an old sock and hang that in front of a return jet and let it dissolve that way. You can squeeze the sock every now and then to help it dissolve faster.

Your pH is too high. Add a little muriatic acid in front of a return jet while the pump is running. Wait a couple of hours, retest pH, and redose as needed. (If you have a sock of CYA there, remove it before adding muriatic acid.) I'd start with a pint of acid. Wear gloves, glasses, stay upwind of fumes, pour close to the surface of the water so it doesn't splash any.

I put 3 lbs of CYA in a knee-high. How long do I have to wait after adding muriatic acid to swim? Once CYA is in a acceptable range, how long should I run my pump each day? My drain is abandoned.

[PoolDoc]

If your pool is circulating, 15 - 30 minutes after adding muriatic should be long enough for adequate mixing.

Work out how long to run your pump AFTER you get the pool operating properly and your chemicals adjusted. Start with 24/7, and work downwards.

Once you get the K-1515, you'll probably never use the DPD test in the K-2005 again. And, just to reinforce what 'Mom said: The ONLY difference between the K2005 and K2006 is the FAS-DPD Chlorine test, and the K-1515 takes care of that for you. It's only about another $20. Also you should have a GOOD OTO test kit. Leslies should have one that uses Taylor reagents and measures to 5ppm on the chlorine side, and uses R-0014 on the pH side. If so, this is the same as the Taylor K-1000, which, IMHO, is the best OTO kit you can buy--and the Leslies kit is the Taylor kit in a Leslies box.
Also, if you are testing CYA often, see if Leslies has the CYA reagent: R-0013 and if they have it in a larger size. I buy it in pint bottles, myself.

I actually have the Leslies version of the K2005...but that's because I have about five different "Service" kits of various types, numerous OTO kits, various single tests, including FAS-DPD, CYA, Salt and Copper.

I am about to call a sand truck to fill in the pool. I have been battling green water for over a week. Except for chlorine (which I didn't test b/c I have been too lazy to buy the supplemental kit), everything is in line. ph-7.6, ta-100, ch-100, cya-40. I have scrubbed and added bleach almost daily - 5 gallons at a time. The water is grass green. Oh, yeah, we're hosting a surprise party Saturday. HELP ME PLEASE!

===================================

I am going to add more stabilizer, too.

===================================

Added 12# stabilizer. Water is beginning to clear near steps. Maybe I panicked for nothing?

But if you haven't bought the chlorine test kit as previously advised, how else can this forum help you?
