Hello all! Looking for a little help! Just put in a new pool, and am going to maintain myself. I've had a pool at other residences for nearly 35 years, so I'm familiar with pools, but this is my first gunite pool.
I started out with a Color Q Pro 7 for testing, but the test results were all over the place and highly inconsistent. I then came across the TF 100 recommended in numerous reviews, so I ordered the kit along with the SpeedStir.
I ran my first set of tests today... and while the instructions appear pretty easy to follow, my test results do not match my local pool pro store results. I have a 6,800 gallon gunite pool with a salt water chlorine generator.
Here are the readings from T&D (Pool Store), and the TF-100:
Test / T&D / TF-100
Free Chlorine / 8.8 / 14.0
Total Chlorine / 10.0 / NA
Combined Chlor / NA / 0.0
pH / 8.4 / 8.2
Alk / 90 / 200
Calcium Hardness / 353 / NA
CYA / 75 / 83
The only two tests even close are pH and CYA. The Calcium Hardness test doesn't seem to work at all... I fill the cylinder to the 10ml line, add 10 drops of R-0010 and mix, then I add 3 drops of R-0011L and mix. It turns pink. I should have had to add about 14 drops of R-0012 for 353... I stopped adding drops after 30 when there was no change.
What could I possibly be doing wrong?
Also - I know chlorine and pH are high. I have backed off my filter hours and dropped the salt cell to 5% to get chlorine levels down, and added muriatic acid to bring down the pH
Right now, I'm just concerned about getting the right test readings.
Any help would be appreciated!
