My friend has an aquarite salt generator. It is flashing check salt and inspect cell. From reading a little it appears that inspect cell is some type of nag alert like in a car when change oil comes on. Can anyone confirm? We did pull out the cell and it has a little bit of scale, very minor I would say and I don't want him to start cleaning it if not necessary. The salt is a little low at 2600 he is going to add more.
