Pump flow set too low for SWG?

[jeffbg]

I'm thinking that I might not be running my pump fast enough for my SWG to be totally efficient. The "enough flow" light is set. Without solar, I'm running at 25GPM.

However, I notice that I see what I assume are little chlorine bubbles coming out of the return lines and bubbling to the surface, so I assume this is chlorine which is not dissolved in the water.

So that got me to thinking that maybe my SWG would be a bit more effective if I ramped up my pump, but I'd rather run slower to save on my electric bill. Last summer when I ran my pumps much harder and my bill was higher, I don't recall seeing these bubbles.

Thanks!

I have not seen a difference in my FC levels when running my pump at a speed that "prevents" the bubbles. If you search the SWG forum for bubbles you find that these are hydrogen bubbles and not chlorine gas.

bubbles are normal...part of the reasoning why we suggest lower TA level for folks with a SWG as it tends to aerate...25GPM seems reasonable to me
