So, am I ready to ROCK???

Pool Mike -

Your SWG's ideal salt range is anywhere between 2700 and 3400, so you're still in that ideal range, per the owner's manual for your unit (I have the same one).

The salt reading dropped from what you saw before probably because your PB backwashed your filter. Anytime you lose water through backwashing or splash-out, your salt reading may go down a bit.

As Simmons99 indicated, you cannot change your salt reading by moving the control knob. Boosting your control knob to 80% won't change your salt reading. Right now, it will stay at or about 2900 no matter where your control knob is set, 10%, 30%, or 100%, or anything in between. Where the knob is set makes no difference to your salt reading. The only way to increase your salt reading is to add salt in your pool water. I'm not saying you should add salt right now, I'm just saying that's how your system works. The only way to decrease your salt reading is to backwash your filter, splash water out of the pool, or drain some water out of the pool.

The control knob governs how much chlorine is "made" with that salt - how much chlorine is generated and put into your pool. In basic terms, the higher the percentage, the more chlorine that goes into the pool.

From what I've learned on this site over the last couple months with a stabilizer that high (CYA 100 which is too high) you need to get your chlorine levels really, really high in order to effectively shock your pool. My guess is the chlorine you're putting in is doing nothing which is why the water is still cloudy.

Now hopefully an expert can chime in with how to lower your CYA or if that's even possible.

Sounds like I may need to then do a manual Shock? Bleach ??

Anyone confirm and if so, how many gallons you think? Thanks

I called goldline and they said that I can use bleach or chlorine tabs/powder. I just not sure how much by the reading I posted above. Anyone help??

I would first get an anwer to the CYA question and how to lower that. It's probably in a thread here somewhere if you look hard enough. I can't remember the answer, sorry.

The CYA level may be more than 100 since that is the limit of the test (the black dot could disappear before one adds enough "cloudy" mixture to the tube to even get to the 100 ppm line).

Unfortunately, the only real way to lower the CYA is through dilution which means partial drain and refill. However, since this is near the end of the pool season and winter closing is approaching, the pool can just be made to have higher than usual chlorine levels until winter closing. Then the CYA may drop over the winter (for reasons that are not fully understood yet). If the pool is in an area where there are winter rains, then these can be used for dilution via overflow (but if it's in a freezing area, then that may not work as one usually lowers the water level below the skimmer and inlet returns).

Hi ya Richard.

Summer still here in Central Sunny Texas.



Water temp is 84 when I checked yesterday.



We can actually swim till about mid October. If I remember last year on Thanksgiving day it was hot and I was wearing a tank-top.

.... Oh so I had the wife today go to wal-mart and add 3.5 gallons of bleach to the pool. We'll see what happens in about 3 hours or so.
