Nice. I'll check Lowes. I think you're right on shipping. I got confirmation yesterday that they use Chloramine in our system, so I'll have to do the chloramine filter. From what I can tell, the filter for chlorine is the same for chloramine, but it seems you need longer exposure for the removal of chloramine. Anyone confirm? I think I might do a 4 stage with 1 pre and 3 active carbon. I need to get a flow of about 60gpd which seems realistic through those filters.

Sorry to hear the bad news...Chloramine.
Look for a filter that says 'Catalytic activated carbon' it breaks down the chlorine-ammonia bond, then absorbs the chlorine, most regular carbon filters don't do much to remove chloramine. Did you notice a problem? Now you have leftover AMMONIA to get rid of. Zeolite will remove it in this slow drip system but doesn't last long (you'll have to do some calc's on that).
Of course all this is flow dependant...too much flow & they don't work...shouldn't be a problem in your case, but I would still monitor it.
Maybe :
1 pre-filter 20 micro (particulate)
1 filter 1 micron (iron / lead etc.)
1 filter Catalytic activated carbon
1 filter packed with Zeolite
Test water quality, and add another C A carbon filter if still shows chlorine.
If you wanted to do a chemical treatment, you could setup your drip system and add a I.V. style drip for a chemical chloramine removal.
Just something else to think about.

Yes, I did notice the higher ammonia when I first setup the tank. I couldn't figure out what was going on. I tested the source and it showed very slight trace of ammonia, but the tank after adding the de-chlor would show a raised ammonia level. I've got such a friggin BB colony in my tank now that if I check ammonia 1 hour after a wc, there's 0. Right now I use a holding tank for water storage and treat it there. After dechlor and sitting a day in the holding tank it reads 0 ammonia.
Thanks for the advice on filtration stages. I threw a WAG at the setup. I'll follow your advice. I guess it's really hit or miss though. Just have to setup and test.
I'm still a ways away from that part of the setup but I'm trying to think it all through first.
