I am looking to convert my above ground to salt and have a question. It's a 17,000 gal and I have been looking at the CircuPool si45-plus. They have a deal where I can get the si45 for the price of the si30, but I hesitate as when something seems too good to be true, it usually is. So I also started looking at the Hayward stuff that is comparable but most of it states that it's for "In-Ground" pools. Seems to me it shouldn't matter as long as the plumbing is compatible, but what do I know. Can anyone confirm that I could use the Aqua Rite for an above ground pool?
