Occasionally one of my family members forgets to turn the spa off and the jets, air blower, heater, etc are left on all night if I'm not around to notice. I'd like to install a user-friendly controller that will automatically turn all spa features off after 5 hours if left on. I have an old...

Nope

Get an electric salt probe from amazon (the testing strips suck) or take a sample into Leslies. Compare it to the manufacturer's recommended levels in the manual to make sure you don't have to add salt (should only need to add a bag or two a year depending on usage or backwashing).

I'm troubleshooting my salt cell since lately the service light has been coming on and off (seems to happen randomly about half the day it's solid on with no visible gas being produced, otherwise sometimes service light is off and working fine). Warranty department has been really slow to get...

I've been doing 12 hours at 100% which did okay, but might have worn it out prematurely as it stopped working after only 2 years. Would be nice to run it less. CYA is at 60

I have a 28k pool and most of the sizes available won't get me the recommended 2-3x capacity. My SJ-40 isn't cutting it and I want to upgrade. Question: if I get the SJ-55 version, is the cell plug and play? Can I just get a SJ-55 replacement cell and swap it into my SJ-40...

Indeed, looking for ideas about where it's coming from and how to prevent it. I have the PSI limit set.

I don't think we're on the same page with the flow function of a VSP. It has two target modes, set RPM or GPM. This is more efficient than constant RPM pumps. If I set RPM mode at 2400 RPM, it produces around 45 GPM, then after a few months (or shorter per this thread) it's only pushing...

The whole point of variable flow pump is to set GPM. If I set 2450 RPM, as soon as the filter PSI rises my flow drops. If I set a target GPM, the RPM will start low and slowly rise as required as the filter gets dirty. More energy efficient.

Sometimes it gets dusty, but not really much in the past month or two. This is a relatively new issue (started sometime in the past few months). Pressure gauge works fine. Low flow and high PSI is immediately fixed when I wash out the filters. FC=2.0 TC=2.0 PH=8.0 CYA=60 TA=100 CH=350...
