Cheers, Eric

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 (total ammonia is both free ammonia and non-toxic ionized forms of ammonia).

I tested my tap water after using Prime® and came up with an ammonia reading. Is this because of chloramine? Could you explain how this works in removing chloramine?

A: Prime® works by removing chlorine from the water and then binds with ammonia until it can be consumed by your biological filtration (chloramine minus chlorine = ammonia). The bond is not reversible and ammonia is still available for your bacteria to consume. Prime® will not halt your cycling process.

I am going to assume that you were using a liquid based reagent test kit (Nessler based, silica). Any type of reducing agent or ammonia binder (dechlorinators, etc) will give you a false positive. You can avoid this by using our MultiTest™ Ammonia kit (not affected by reducing agents) or you can wait to test, Prime® dissipates from your system within 24 hours.
