Ammonia is new salt water mix

Have you tested your tap water for Chloramine?
Your LFS should test it for free for you.
But that's something to look into...
 
I fill it with tap water (not RO/DI, unfortunately)

Using tap water is enough to say why this is for many years ago before there was ever a skimmer, I had setup two 55 gal tanks for my water changes running carbon and I cannot say that it was always perfect for also at that time because on the type of equipment we had back then I stayed within FO tanks. I done those 55 gal tanks in my garage for I not then had a large house as I do today. But I think it was suggested to you to test your water on all the test available for city tap water is worst today then it ever has been.

Like before I moved into my house more then four years ago, at the apartment I was I only needed to use one HI-S DI cartridge and after moving here I learn that I needed two. The water is worst here where I live now then anywhere I ever lived.

I can only suggest to you to get away from the tap water and buy yourself a RO unit.

using tap water and dechlorinator..
I suspect you may actually be seeing the effects of chloramine.

what dechlorinator are you using?

some will break the chlorine ammonia bond and bind H to NH3 turning it into the less toxic ammonium NH4
most test kits test for total ammonia (NH3+NH4) you may actually be seeing the NH4
you can find out by testing specifically for ammonia NH3..the difference in the readings will be NH4.(total - NH3= NH4)

Just a hunch

Thanks for that. That is really a good point in that we should all try to be more educated about reef chemistry and what it is exactly that additives are doing in our tank versus the benefit listed on the bottle.

This is correct. I had posted on this awhile ago, but I think it's worth repeating. The water conditioners don't "get rid" of the tap water impurities (they don't just magically disappear!). The convert them to something that is not toxic (or at least less toxic) to the fish. If your municipality uses chloramine, the "amine" part is still there - and could show up on the ammonia test. At the very least, it is still available for nitrifying bacteria to convert into nitrates.

If you are treating tap water, make sure you know whether it contains chlorine or chloramine. Chloramine is much more toxic to fish, and not all conditions neutralize chloramine - check the label to see if it can be used for chloramine.
