Thanks all for the info on liens and the jets. I was not positive on the size of the fm threads. Just got back from home depot with a 1.5" male cap and it fit the pool return pipe - so it was not 1.75"
Numbers look good. FC is a little high. Shoot for 5 or 6, don't let it go below 4.
York: The FC drops real fast so I was changing the target to 7. I'll keep the target at 6
I wish CSI was higher. Are you actively pushing pH down, with MA? If so, let it come up. 7.7 or 7.8 should give you a near zero CSI. See if your TA stabilizes at that pH.
York: I thought CSI's desired range for chlorine pools was -.3 to +.3 or -.6 to +.6. and -.3 to 0 or -.6 to 0 for SWCG
Yes MA is added daily. It creeps up real fast as well. I thought it was better to keep it a tad under 7.5, and that 7.8 was too high.
Be sure to test salt before you add any, and put the result into the "Now" column of Pool Math, to then determine how much to add. Don't assume salt is zero.
So add 1800ppm of salt to bring your 600 to 2400ppm, let it mix in for at least a day, and then see if the SWG will fire. If it does, you're done. If it won't, then add another bag, wait another day or two, then try again.
After the IntelliChlor SCG is powered on, the LED salt level lights will blink from bottom to top for two (2)minutes while it analyzes the pool water, then the LED indicators will show one (1) of four (4) salt level ranges.See “Salt Status LEDs” on page 7 for more information.
•3600 ppm of salt is recommended for optimum water condition.
•Low salt concentration below 2600 ppm will cause the unit to turn off
•High salt concentration above 4500 ppm may cause excessive corrosion or deterioration to poolequipment and surrounding surfaces in and around the pool.
Note: Salt measurements will vary between measuring devices (salt test strips, electronic testers, andtitration). The salt sensor reading is within +/- 500 ppm accuracy. For more troubleshooting information about high salt levels, see “Troubleshooting,” on page 28.
... Exceeding the recommended range for FC (based on your CYA level) will only help to burn it off faster. But protecting the low end of the FC range is more important than exceeding the high, so do what'cha gotta do for that.
With your ability, and willingness, to test pH everyday, there's no reason not to shoot for a CSI of 0. Pushing the lower end of the range gets you that much closer to "etching territory." When the SWG comes online, it's -0.3 to 0. Why not target -1.5? Not obsessively, just target the midpoint (by manipulating pH) and let it settle within that range.
7.8 is not too high. And targeting lower might be a losing battle. CSI is more important than pH when it comes to pool health, as long as pH is within range, and 7.8 is within range.
As you continue your battle with rising pH, you'll start to notice that your pH will want to settle in the high 7s, especially when you go SWG. Let it. Forcing it down to some arbitrary lower number will only make it snap back to high 7s that much faster. What I've found in my pool is that dosing down to 7.6 and letting it rise back up to 7.8, or 7.9 doesn't happen all that much faster than if I push it down to 7.2. Going down to 7.2 only messes with my CSI, like it does yours...
