I hope I can get some answers from the experts here. A little background on my pool. I had it installed last year, approx 30k gal, gunite with hydrazzo finish. I am using all Pentair equipment including an Intellichem which runs my IC40 with a Quad 100 taking care of the filtering. PH is kept in check with a Stenner dosing pump handling the Muratic acid.
I have read posts that the Intellichem using ORP to control the Intellichlor is not the best way to go because as the CYA reaches the upper levels for a Salt water poo (80-90) the ORP probe gets wacky. With that said I have kept my CYA 10 points above Pentair's recommended 50 to 60ppm to try and find a happy medium. But even at this level FC levels cannot be maintained and instead of being 650 ORP my reading will slowly drift to 300 range after a week and green algae will form on the walls unless I supplement with Bleach... Yesterday at Pentair's request I did a "bucket test" with the IC40 and yes it is producing chlorine.
My issue as I have stated in my title is my Chlorine is being burned off at such a fast rate that the IC40 Intellichlor cannot maintain appropriate FC levels and basically runs at 100% the entire filter cycle per day, 12 hrs. I find myself having to put bleach in at a non shock levels to keep the FC at 2-3 levels. Now I am not shocking it, this is just to maintain my FC levels. After much reading here and trying to educate myself the only culprit seems to be high Nitrates and Phosphates. My Phosphates where 600ppm so I did a Phosfree run and got them down to their current levels of 300ppm. As of today my current chem levels are as follows, done at my local pool store and backed up by my Taylor 2006 kit:
FC: 2 (I put in 1 gallon of 5.25% bleach last night otherwise it would be lower)
TAC: 2
PH:7.6
TA:90
CYA:60
CH:270
Salt:3500
Copper:0
Phosphates:300
Nitrates:60
PS: I had no issues last year at all and the pool was complete on Memorial day so we got to use it the entire season. I closed the pool in late October and I opened it in early April. I live in the Northeast specifically Northern NJ.
Thanks in advance.
