Hello, I'm sure this has been addressed but could not find a specific post in the forum. I have struggled with chlorine in the pool for weeks and tried everything but cell replacement. My pool company agrees there may be an issue and says I have to replace it with a GLX-Cell-15-W. The replacement cell only has a one year warranty. That makes me nervous for obvious reasons. Why the different name on the cell and why did I just loose 2 years of warranty (T Cell 15 Warranty is three years)? I've only had the first cell for 6 months. I've maintained almost perfect water chemistry and there was no buildup on cell or any obvious reason for it to fail. Anyone know the difference in these cells and why the difference in warranty? Should I insist it be replaced with a T-Cell 15?
