Decision on Zeobrite or Sand replacement

[waterbear]

Don't know if this will help you but zeolite filter medium (which is what Zeobrite is) has been used in freshwater aquariums for many years now precisely for it's ammonia scavaging properties. It is not used in salt water aquariums because the ammonia scavaging properties are greatly reduced in salt water and the salt CAN release the ammonia compounds from the zeolite that have been trapped back into the water (usually when pH drops) which can prove lethal to the livestock. It seems to reason that the same might happen with a SWG although the salinity is about 1/10 of seawater. The cleaning procedure for Zeobrite is a very concentrated salt solution/sand cleaner mixture that is acidic according to the company's website. The result if ammonia is released back into the poolwater might be combine chlorine although this is just conjecture on my part... there is a possiblity that at normal pH and salt levels in a pool with a SWG there is no noticable effect at all.
An interesting question!
