Second, if you're refering to the stock 'ammonia remover' insert (Amrid), that as well as the carbon (Zeolite) insert is not really necessary for the A/C to function. Save them for an emergency & increase the 'bio media'. You'll find that this move will have your A/C funtioning more efficiently & less costly. "T"
So your recommending using the sponge and then two layers of the bio-media, no carbon?
Pot scrubbies are good for sumps or large cans like fx5. But you could'nt fit to many in a ac70. So the biomax is a better option.killarbb;2404386; said:post scrubbies are cheaper than biomax
