SWCG build up

[Rodex]

I have been running my new VS pump at the suggested speeds for the last few weeks, and I noticed that the newish SWCG seems to be quickly building up junk on the plates. Should I be concerned?

Rod,

That looks like dirt or debris..

What you don't want is white calcium deposits, which will make your cell quit working.

Try to keep you CSI level between 0 and -.3 to keep the calcium scale as low as possible.

Thanks,

I do try to keep it there but right now I’m sitting at 0.66, which has probably been there for a couple of weeks as I’ve been out of town.

Seems like I could wash it out if it’s just debris?

One thing to note is that the water level inside the SWCG only seems to be full when the VS motor is at full speed.

That looks like pollen on the outside of the SWG. Rinse it off with some water and see if that helps.

Rod,

Not sure about your SWCG, but some manufactures recommend that you mount the cell upside when using a VS pump at a low RPM. Might want to check your manual.

Thanks,

Your pH is a bit high. Bring it down to about 7.6-7.8 -- that will also get the CSI closer to zero.
As you lower the pH, the TA will lower a little bit also. Shoot for a TA in the 60-80 range. This will allow you to run the pH at about 7.8-ish and probably keep the pH more stable.

Fill out your signature with your pool, pool equipment (manufacturers and model numbers) and test kit info. This helps us to better help you.

Is that not showing up already? I can see it on my posts….

There is definitely something on the plates internally, it’s just hard to get a good picture.

Dump a cup or two of water on the outside of the cell to rinse any dirt/pollen off.

If your pool water CSI was .66 then the CSI in your cell during FC production was significantly higher leading to rapid calcium scale on the plates. Continue to lower your pH and that will lower your CSI. Because your TA is high at 110 your pH will continue to rise rapidly until eventually you will get your TA down to 60-70, then the pH rise should slow. Test your fill water for TA and if it is high then stock up on MA for the summer months when evaporation is high and you are adding tap water. Monitor your cells power usage for clues on cell plate fouling. If your unit provides a run time estimate of salt ppm and it drops significantly that is an early sign of scale buildup and the unit may need to be serviced eventually. Confirm your waters actual salt ppm with the K-1766 kit first before doing anything. Be wary of using acid to chemically clean the buildup on the plates as it will negatively impact the Ruthenium coated titanium plates.
There is good vid at the TFP site on Utube that details water chemistry and cell maintenance for SWCG systems.

The TA of the fill water here is high, so you are correct, in the summer it’s a beat down of managing TA and dumping MA in. It seems to be happy around TA=80-90 and pH = 7.8-8.2.
