Bought a new RO/DI from Bulk reef Supply. (BRS 6 Stage plus water saver W/ 2 DI resin chambers. I am running on a well. I have 147 tds tap water. 9 tds after prefilters. 0 tds after first resin cartridge and of course 0 tds after 2nd cartridge. this is my 3rd Ro/DI system because the first was a cheap one. the second one gave the ammonia reading in the R/O water So i bought the biggest badest RO/system I could find. its been running on a ro buddy pump at 60 psi for 3 hours and have made about 15 gallons. I have a .025 ammonia reading. Any help would be apreciated as my corals have been without a water change and the need it due to high nitrates in the tank.
Ammonia after RO/DI System.

+1 Gah, chloramines are such a PITA. It seems like more and more water sources are using them too.
Then no, it's not likely chloramines. I'm not too sure about well water and what you might possibly need to filter out of it. I would talk to Buckeye Hydro and see if you need a special filter. Is this right after the DI stage and before you add salt that you're getting the ammonia reading? Is it possible to have a LFS doublecheck your test?
You should not have ammonia in your well water unless you are on a farm with excessive fertilizers or animal waste. Are you rural? On a farm? Nearby farm?
Second point: The filter ratings are extremely important. The "unit" is not as important as the filters. Not all filters are created equal. .5 micron absolute is different than .5 micron nominal. You want to make sure your filters are absolute rated.

I got nothin'
Where are you storing your water.
I would check your water directly. Let it drip into the test tube.
Then check the water in the container after it’s been sitting for a while.
A few people have reported ammonia in water from their holding containers, do a search for the threads. I don’t know if anyone ever figured it out.

I do live near a farm but im up hill from it. I only get nitrates out of the tap. I get .25 ammonia strait from R/O unit. I get between 5.0 and 1.0 from Brute trash can when full. Afraid to use the water even if I add prime. 1 micron R/Osave.Z sediment filter, 2 x 1 Micron Universal Carbon block, 2 x 75 gpd dow filmtech RO membrane, 2 x dual color changing DI Resin. the filters came from bulk reef supply with the unit.
Something doesn't seem to add up. I don't understand why the RO unit would produce ammonia if you are getting zero readings from the tap. Unless maybe your DI is saturated and releasing ammonia back in?
We need some of the water experts to chime in: BuckeyeHydro, Spectrapure, AZDesertrat.

And when did you get it? 3 years ago? 3 days?
Also do you keep it covered?
Did you ever answer what product you are using for ammonia testing either?
API test kit? something else? what?
Did you test your well water for ammonia?
We are trying to help and the answers to ALL the questions are necessary for us to do so.. Not just a few of them.. ALL questions.. Each one could hold the clue to the answer..
You should post a new question in the reef chemistry forum using the information and answers from this thread.
Either your test kit is wrong, or there is a substance making it through the RO membrane and resin that is breaking down to ammonia. I'm no chemist, so I'm at a loss.
