I just bought some drinking water from walmart to do a water change. Just for the hell of it I tested it and it was good except for ammonia was at 0.50ppm is that right?? How could you sell drinking water that has ammonia in it??:confused:

Water is purified often with chloramines. Chloramines are compounds of chlorine and ammonia. This is one possibility.

Other possibilities are increased incubation time, test error, or expired reagents. or the test lower linear limit does not go to zero.

Totally agree with angelsj. Drinking or spring water is bad choice. In addition to ammonia, chlorine, chloramine, there could be sulfates, copper, nitrates, and only god knows what else they put in there.
RO/DI or distilled is your best bet.

In any case you could check TDS. For SW it should read < 10.

SW = Salt Water
TDS = Total Dissolved Solids

It might not be as much an issue for you since you have a fish only tank but people with reef tanks like to start with VERY pure water (0 tds).

Anyway did I just waste 12.00 or is there something I could put in the water to make it safe? Or just throw it down the drain?

TDS meters are for testing total dissolved solids (check out http://www.bestlabdeals.com/product_p/mil0006.htm prices there are not so hot, but it will give you an idea on what it is).

IMO, LFS advise should be treated as just one person's oppinion. Get more answers on the subject and evaluate what makes sense best. Some LFS will give you an excellent advise and some are just here to sell you denitrator reactor to help battling nitrates from your water source :)
