True... The PH is always high... I used to keep after it quite regularly. Never really tested the TA. The ecomatic cells have a rubber tubing that covers part of the leads for the cell. This rubber tubing cracks over time and the leads rust fairly quickly after that. I will try to post some pictures. My real question is before investing in another cell, should I consider replacing/upgrading the SWG? I don't see many postings regarding the Ecomatic. I do like the system, other than the weak point of rubber tubing covering part of the cell...
