I'd been under the assumption that I had about a 7500 gallon pool as it's an 18' round with a deep end (about 5'8" or so) so I added 200lbs of salt after having converted from Baquacil to a Aqua Trol RJ SWG. The test strips show salt to be at 4500 ppm whereas the Aqua Trol has slowly moved up over the week to 4000 and has dropped back down to 3800. I used Jason's pool calculator and put in the 0 to 3800 salt level to equate to 200 lbs of salt and adjusted the pool size down to 6300 gallons for it to equal out. So using the Aqua Trol's salt reading my pool size is 6300 gallons.
However if I use the salt strips figure of 4500 ppm my pool size would be 5300 gallons. Most likely the salt strip is not that accurate - if I leave it in the water 3 or 4 minutes like it says I get a reading of about 3000 (which would seem more reasonable) but left in until it actually stops moving its up to about 4500.
The actual pool size is an 18' round with 41" of water in it and a deep end of about 5'8". Using Jason's pool calculator and assume no deep end whatsoever where the pool is 18' round and 41" deep the pool should be 6600 gallons. This again is assuming no deep end whereas mine has a deepend of about 5' 8" or so, so it should be considerably more than the 6600 gallons.
However the salt strip, Aqua Trol, and water taste (seems a bit too salty but having never swam in a SWG pool I couldn't know for sure) would suggest too high a salt content. What would cause this?
Just in case any of these other chemicals could affect the salt level here are the current results - my FC is 6 right now (I turned the SWG dial down to 1% yesterday or the day before to get the FC to drop), PH is 7.6, CC is .2. CYA is 65. TC is 100 (not adjusted for CYA so probably about 90 adjusted). CH is 160.
I was thinking I needed to drain water to get the salt water reading down to 3200 if needed. Based on the pool caculator each inch I drain this pool equates to about 200 gallons of water. How much water would need to be drained to drop the salt reading to 3200 from 3800?
