Hey, we have a 20' X 4' Intex pool that is a couple of years old. The ECO SWG is showing low salt almost everyday. I've read that usually means it is dieing or dead already. I can pick up another one pretty cheap, but wondered if there is a better replacement setup? We are probably 2 years out from going inground, so really only need to keep things going for that time frame. Currently we have a large Hayward sand filter and 2hp pump that does a good job moving water. Just need to keep the chlorine up.
