I have an Aquarite T-CELL15 SWG, I bought one of those premixed bottles os cell cleaner solution that you can find at your pool store, it wasn't cheap, around $20 for a 2Litre bottle.
Anyhow, I bought myself one of those cell stands, I had my bucket all ready, I first rinsed out the cell with a hose and then I fitted it with the stand and I poured almost the entire 2Litre bottle of cell cleaner in the cell, enough so that it covered the cells.
I left it there for around 30ish minutes but there was no fizzing or bubbling and I don't see any of the gunk from the cells removed, in fact I emptied the content of the SWG in to the bucket and the liquid looked clear.
The cell cleaner was purchased about two years ago but had never been opened, but it had been stored in my cabana throughout the winter and summer months.
Did it lose potency? What should I do next?
