Thx waterbear. I really didn't want to start to explain that saltwater is the recomended cleaning agent for zeolite, and when it 'cleans' the zeolite it is widely known that it releases stored ammonia from the zeolite. Therefore, if you're running a swg constantly, the zeolite is constantly being 'cleaned' then ammonia is constantly being released. Obviously it will be in such minute amounts, and dilution as you point out below, that it will not be an issue what-so-ever. And to take it to a farther logical point, will zeolite ever be able to 'absorb' any amount of ammonia if saltwater is passing over it?
Which makes the whole question of ammonia release kinda moot.
My issue was that I didn't want to invest in z-lite if this cleaning ability is one of it's strong points and I was stifling it by using the media in an swg pool.
I'm replacing my sand anyway so it doesn't matter.

Guess we did end up 'splaining it, Lucy!
