Opened pool and problems...

[chumpy36]

ok, the last two days of testing seem to indicate the chlorine levels have stabilized a bit. I think.

Two nights ago, the readings were

FC 11ppm
CC 5.5 ppm

I added bleach in the amount the pool calc said would get me to 15 but either my volume is off or I made a mistake in the form. The next evening (last night) the readings were:

FC 19ppm
CC 0

This morning I tested again and it was:

FC 15ppm
CC 1

Pool is still very cloudy. Doesn't seem to be improving much. Pump pressure does rise. I am using DE in addition to the sand. I'm wondering if at this point the filter needs the sand replaced or maybe is channelled. The pool sand was replaced 6 years ago.

Any ideas about what to do now?

Thanks

You don't need to replace the sand. I think I am on my 10th season with the same sand. Poconos and CarlD also have the same sand that they have used for at least that long. Not sure about Aylad. At any rate, I think your sand is probably fine.

Can you post a total set of your other numbers? This thread is getting pretty long. I'm sure you gave us all the numbers before, but we are now on the second page of this thread and it is difficult to have to look back so far. Give us current alk, cya, calcium hardness and pH again please.

At this point, are you adding anything other than bleach? Are you running your pump 24/7?

My current sand is 2 years old, but only because I replaced my filter at the beginning of last season. The sand in the old one was 7 years old and still doing fine. Had some issues with the filter due to improper installation by the company that installed my pool.

Ok here is the new set of number taken last night....
FC 13
CC 1
PH 7.6
TA 220
CH 50 (I think - the test wasn't really definitive for me. When I added the 5 drops after the 20 drops of calcium buffer it didn't really turn red, more a hint of pink if that)
CYA 20-25

I have not added anything other than Bleach and one box of borax since we started this process. Pump is going 24/7

Thanks

Looks like you're making progress!! Keep it up!! Sometimes it just takes awhile for the filter to get it all. If your pressure is still rising while the pump is running, and goes back down again after backwashing, then your filter is catching the stuff.

Ok, so I'll keep going but do I let the Chlorine go down at this point to maintenance level? Also, should I think about upping the cya? Is it time to do anything about the high TA?

Thanks

With a CC of 1, I'd still maintain the high cl for a while longer. Don't worry about anything else right now. The other things can be adjusted a little later.
