RO/DI Problems

Is it possible for an RO/DI unit to actually produce Ammonia and Nitrite? I tested some of my fresh SW before putting into my tank and it showed trace amounts of both ammonia and nitrites. I posted a similar problem a month or so ago, but the water I was testing at that time had been stored for about a month. This water had only been stored a day and I'm getting readings like this.

If there was already Ammonia and Nitrite in my tap water, wouldn't the RO/DI filter take those contaminants out? That's why I think that the problem is the RO/DI Unit.

Maybe my test kit is crap? It doesn't say that it is expired though.


:help:

I don't think that its that the quality has gone down. I think that it's been like this since the beginning. It would explain why my cycle has not ended.

Thanks for the links, Sub.

Great. Just great. As if everything else wasn't complicated enough, now I have to deal with this issue. QT or no QT. UV or no UV. What salt to use. What substrate. What fish. What lights, etc.

This is just one more thing to spend money on. If I new that this whole chloramine thing was a problem I wouldn't have bothered with setting the **** tank up.

I still need to test the tap and waste water, but It isn't looking good at all so far. What else could be causing the Ammonia after the filtration? Granted it isn't a large amount, about .25ppm, but still, there shouldn't be anything after RO/DI.

If my tests confirm what the links indicate, then I'm pretty much done with setting up this tank. There is no way I'm going to waste money setting up some damned HCl dripping system to lower the pH of my tap water.

I just checked the Water Quality Report for my water and it lists the use of Chlorine as a disinfectant. It doesn't say anything about Chloramines. I'm still going to have my FW tested. If there is no Ammonia then it has to be the RO/DI unit for sure.
