If you know your actual salt ppm (K-1766) and monitor your cells calculated salt ppm you will get a clue of scale fouling when observing a significant reduction of the calculated salt ppm over time. You can also monitor your cells performance by observing the voltage and amperage during...

Waiting on the K-1106 to test PO4 and it should be here in a few days. Right now I am actually finding comfort adding liquid chlorine each evening and confident my FC level is in the zone for the next 24 hours. I don't miss having to check my salt cells operation every hour only to eventually...

Each time I have used the diluted acid on the cell plates I have first used the pressure hose and manually removed the scale prior to treating with acid. I did not observe the fizz reaction after that but it seemed to soften small areas I had missed manually that then were removed after a...

This is season 2 for this unit and while it was cleaned 3 times last year, I never used acid only the plastic zip ties. This year I had trouble one day after the first manual only cleaning as the the low salt light was back on after powering up the unit for one cycle and no obvious plugging. I...

Thanks Pat and James, I see a step by step process of elimination and testing in my near future before I can make any real progress with this. I am close to determining if the cell cleaning method has any effect. I will need to go deeper in the water contaminate possibility before making a...

My SWCG has become unreliable. After cleaning #2 in as many days the cell had a low salt shut down after another 8 hours at 65%. A clean cell, normal high salt (4500ppm) reading in the morning with a strong amp number falls off after several cycles and finally shuts down mid afternoon with a...

CP recommends filling the cell housing with 1:4 MA until the reaction stops, from the owners manual. Not sure I have a valid complaint until I follow their recommendation. They also stated that the cleaning process may involve 2 or 3 cleanings. I was waiting for this process to proceed before...

Matt these plates are locked in tight and offset in this cell housing. Opening it up with a sawsall or hammer would be the only way to get a good look. Hard to imagine how the Ruthy coating could have been damaged that bad, that fast to cause this situation with only zip tie cleanings all of...

No scale inhibitors and I may have a water quality test done last year from an ag lab that details the Phosphate level and TDS then. I may want to run a current test. I did the fizz test and there was a rapid reaction and the sample was completely dissolved after a bit of agitation. I...

Yes pull the ladder, drain and chlorinate the space inside. This is your algae nursery I believe.

Just checked cell and it is operating at 20.+ volts, 6.3 amps with a calculated salt of 4300ppm. No significant difference at 1350 vs 2300 rpm. This is consistent with a recently cleaned cell in the morning, my experience.

Thanks mgtfp, I have played with run speeds over time for this reason. My initial observations over the last two seasons of the cell operating during low vs higher rpm is a reduction of the amp draw and a lower calculated salt ppm at higher pump speeds vs lower, 2300 vs 1350, but this was not...

Thanks Jim and BPerry, yes with my system I have the flexibility to run a negative CSI. Jim your suggestion seems to me to be going the wrong direction if I want to slow scale. I have been running my CSI well below -.6 for nearly 2 seasons now in an effort to slow down the scale buildup. Last...

After a recent cell cleaning, yesterday, my RJ-60+ shut down again today (low salt, cell maint light) after maybe 6 1/2 hours of actual run time (10 hours at 65%). This is not the first time this has happened. I watched the voltage rise slightly and amperage numbers drop off a cliff in 4 hours...

Scale recovery

When the pool water temp rises the scale accumulation speeds up. When the pH is in the low 7s the scale tends to be softer and is better removed with the polarity change. When it's time to clean I like using zip ties of different widths and stiffness. I also cut the ends at an angle to reach...

You could utilize reverse osmosis to lower your CH but there is still some water loss involved, check with local companies offering this service. Is your salt cell loading up with calcium scale?

Because we live in the Central Valley and it is the middle of almond harvest season? Dust is in the air. Suction up a sample of the debris you are seeing and filter the solution through a coffee filter then let it dry. I like to use a 1/2" PVC pipe holding my thumb over the end until over...

Welcome to TFP. Your cord is not sticky because of algae, this seems to be a common issue with leaving a bot in the pool, not sure why but assume it is a reaction with pool chems. Heads up that all may not be fine with your pool water and relying on test strips is a big red flag. Strips are...

Tread wear is related to the pool surface and a pebble finish wears down the treads faster than a smooth plaster or fiberglass surface so factor that. My treads are still in great shape but I too have replaced my fine filter panels after several seasons as the pleats began to distend. My...

Stabilizer is very important at the correct level, too high or too low will give you problems. Start at the beginning by knowing your water chemistry with an accurate test kit that you use at home.

Check your owners manual but I remember the target is 3000ppm to a max of 3500ppm salt from sodium chloride, NaCl. Test your current salt level and adjust prior to adding more. Approach target in stages to not exceed.

You are correct in your thinking. Adjust the speeds and run times and observe the results to find the ideal setting for your system.

I found several 2" thin, stiff wires on my pool bottom and finally discovered they were shed from the center core of an old push broom I used around the pool. The rust spots eventuall came off with light sanding with wet/dry. The wires are impossible to get out with a leaf net from the deck...

The sock method suspended in front of a return jet is the best practice short of spending $+ for liquid stabilizer. At most after saturation massaging the sock several times over 24 hours does the trick every time. No issues on my bare hands. As for the other poor methods you list, I agree...

Adjust your water chemistry to run a negative CSI. Having a fiberglass pool gives you more flexibility. https://www.troublefreepool.com/wiki/index.php?title=CSI_and_LSI https://www.troublefreepool.com/calc.html

More options, more better. The VS pump is a big benefit when the pump is run for many hours of the day and electrical rates are high. Many pool owners operate a Salt Water Chlorine Generator which can operate at pump RPMs as low at 1200 to 1300. Dialing in your system allows you to observe...

At 30ppm CYA your salt cell would work harder to make up for the increazed FC loss due to solar radiation. The upside is if for any reason you do get an algae outbreak a lower CYA will make the SLAM less costly. Monitor your daily FC loss as you raise CYA by 10ppm to find your sweet spot. I...
