most test kits give you total NH3. if you are using prime or have a low PH then most, if not all, of the NH3 is in the form of NH4. which is harmless to fish.

a salicylate ammonia test kit will only read the bad ammonia. most people have the nessler test kit, which reads ammonium as ammonia, giving you a false positive reading.

Perhaps you need to add more Prime. It says in the instructions that you need to use more when detoxifying higher levels of Ammonia.

fyi from www.seachem.com,

Q: I am using Prime™ to control ammonia but my test kit says it is not doing anything, in fact it looks like it added ammonia! What is going on?
A: A Nessler based kit will not read ammonia properly if you are using Prime™... it will look "off scale", sort of a muddy brown (incidentally a Nessler kit will not work with any other products similar to Prime™). A salicylate based kit can be used, but with caution. Under the conditions of a salicylate kit the ammonia-Prime complex will be broken down eventually giving a false reading of ammonia (same as with other products like Prime™), so the key with a salicylate kit is to take the reading right away. However, the best solution is to use our MultiTest: Ammonia™ kit... it uses a gas exchange sensor system which is not affected by the presence of Prime™ or other similar products. It also has the added advantage that it can detect the more dangerous free ammonia and distinguish it from total ammonia (which is both the free and ionized forms of ammonia (the ionized form is not toxic)).

EDIT: i see joannde already posted this in another thread. nvm

My KitchenAid fridge water filter claims to remove ammonia/chloramines, plus a host of other stuff. However, this filter is like $40 a shot & lasts only so long .... so really only good for drinking water .... doing large water changes with something like that will cost $$$

BTW - I am reading your many threads about your bad water ... my bottom line opinion is to just use prime for your water and don't worry about ammonia of .25 ... your biologic filter should take care of that.

One other thought ... your water has up to 12 ppm of chloramines, which will give you 12 of bound ammonia (assuiming you add enough Prime). I am not sure if that high a level of bound ammonia will interfer with even the Salicylate test. Most people talking about Salicylate tests & bound ammonia are talking of 1-2, not 12! If the above quote is true, <that the salicylate test will eventually break down bound ammonia and read it as positive> then the higher the bound ammonia level to start, the less time you have to read the ammonia before it turns false positive.
