Hi, My pool is 10k gal and have goldline t-15 cell. I keep getting the low-salt and inspect cell led on. I clean the cell (acid bath) and took the water sample to leslie pool for testing. The salt level is aroung 4600. I drain my pool about 6''. I have 2 questions. 1) can the cell stop working because of the salt leve too hi? 2) can I use t-cell 3 (for 10k pool) with my controller? I don't know the exact age of the cell/controller. It was installed when I bought my house. Thanks, Ted
