JohnRoss Posted July 18, 2010 Share Posted July 18, 2010 I have a Bio Pool chlorine producing system for a salt water pool. Is there any value in reversing the connections to the electrolytic cell from time to time? This unit does not auto reverse as the current indicator, which I have temporarily connected in series with one of the electrodes, shows current always flowing in the same direction. Electrode current seems normal, just a tad over 10 amps, but chlorine production seems a little lower than usual despite being on 100% setting. I could add more salt but electrode current is near the top limit for the box. The unit is 9 years old and given good service up until now.........JR Link to comment Share on other sites More sharing options...
Théière Posted July 18, 2010 Share Posted July 18, 2010 Are they showing signs of build up of calcaire etc, if they are clean no need to. Link to comment Share on other sites More sharing options...
JohnRoss Posted July 18, 2010 Author Share Posted July 18, 2010 Hi and no signs of calcium on the 5 plates, all the same colour black. I have tried reversing the connections to the cell and interesting result. On switch-on the current was much the same but within a few seconds had fallen to less than 1 amp. On putting the connections back to normal the current was again just over 10 amps. Reversing again, same result, weird! I did this some years ago and I don't remember getting this effect then. I guess it would suggest that the cell has become polarized in some way. Any harm in leaving it reverse connected for a bit to see if anything flakes off or changes I wonder?...........JR Link to comment Share on other sites More sharing options...
Théière Posted July 18, 2010 Share Posted July 18, 2010 Hmm, how much is a new power supply? Link to comment Share on other sites More sharing options...
JohnRoss Posted July 18, 2010 Author Share Posted July 18, 2010 Sorry I am a bit thick today! Are you saying that doing this might duff up the PSU? Don't think it is already knacked as ok when connected normally. Have now reconnected it the right way and current once again normal. No signs of flaking on the plates. Any further thoughts anyone?.......................JR Link to comment Share on other sites More sharing options...
JohnRoss Posted August 26, 2010 Author Share Posted August 26, 2010 Well still producing chlorine sometime later but did put another bag of salt in the pool which seems to have solved the low chlorine situation as levels are now normal but cell current only slightly higher.........................JR Link to comment Share on other sites More sharing options...
Théière Posted August 26, 2010 Share Posted August 26, 2010 It's difficult to say JR. I noticed that the new chlorinators alternate the polarity to self clean and also some are now able to work well on lower salt levels so must have beefed up power supplies.The important thing is it's still working.and as long as you can produce enough chlorine to keep your pool safe, what % power setting do you usually run at?

JohnRoss Posted August 26, 2010 Author Share Posted August 26, 2010 80 percent most of the time..................JR Link to comment Share on other sites More sharing options...
