Not a pool newby and I'm normally have been really on the money with my self testing and pool maintenance for the past 10 years. UNTIL THIS SEASON!!! I have a 17100 gallon above ground vinyl pool. I CAN NOT get it clear and the TA is going everywhere with each test. It looks like swamp water!!! Ive become somewhat of a stalker on this site the last week and am doing anything I see on here that even comes close to whats going on with this pool. WE HAVE NO POOL TESTING OPTIONS NEAR HERE so I have no back up. Below are the specs
17100 gal above ground pool
in FULL sun all day
I have a top of the line (just bought last season) Hayward sand filter but we add ZEO and DE as media not sand
I have always used triclor tablets in the skimmer per recommended package dosage for a FC of 3
I use baking soda for TA
aquachem's PH up or down depending upon need
I have always used test strips that measure FC PH TA CH CYA and until now have never had a problem.
Now using 8% clorox per poolmath calculations
My PH and TA are all over the place with each testing Why is that/
ROUND 1 LEVELS
ADDED BAKING SODA AND CLOROX AND DID A 40% WATER EMPTY AND REFILL (EST) PER THIS SITE POOLCALCULATOR
Dropped the ph back to 7.0 with PH down and the TA came down to 100 so I aerated to bring the PH back up over night
ROUND 2 AS OF 7AM THIS MORNING
I SLOWED THE AERATION, EMPTIED AND REFILLED more water AND ADDED 1 GALLON OF CLOROX (8 TOTAL IN 2 DAYS)
as of 1pm today
PH (DROPPED BACK) 6.8
I INCREASED THE RATE OF AERATION ONCE MORE
BUT THE POOL IS A LIGHTER GREEN BY 3 SHADES...RIGHT DIRECTION??
WHAT AM I NOT DOING???? WHY IS THE PH AND TA SO UNSTABLE? WHERE SHOULD MY FC BE IF I GET IT CLEARED USING CLOROX? CAN I EVER GO BACK TO TRICLOR TADS ( MUCH EASIER TO DEAL WITH WEEKLY) HOW HIGH CAN MY CYA BE FOR THIS POOL?
