Has anyone tried the ammonia alert system it sticks to the inside of your tank and reads safe,alarm,alert and toxic i just purchased one just wanted to know if anyone had any oppinions on it.

I have had one in my tank for over a year and I think it works (but I've been fortunate enough not to have any ammonia spikes). To be sure I still do water tests now and then....Seachem's alert is made to pick up on the gaseous form of ammonia, which is supposedly the more deadly kind. It also will not give false readings when you add water conditioner like Amquel. (When you use a Nessler reagent test, the use of Amquel can give false positives) Either way, it's a good safety measure.

I have one on each tank. So far no ammonia spikes for me. I tested one of the alert things by holding it over an open bottle of ammonia, and it changed color pronto! :gbanana :rbanana

I had one for a while, but the little sensor came off after a couple months, and I just never bought another one. I hear they work very well, though. And it's helpful when you add fish or change something about your tank to have something constantly monitoring things like ammonia.

I want to get one of those digital devices that monitor ph, ammonia, and nitrite constantly. I hear they are really expensive though- and hard to find!

Ya that digital one sounds very good,but yeah it must be hard to find i didnt see one at my local fish store or petsmart hrmmm.i will have to keep a lookout for that one.

My sensor is on safe right now and i tested my water and i have 1.0 amonia hrmmmmmm lol

Cool, so nice to have such nice equipments... I haven't seen them around yet or maybe I have not searched hard enuff...

I'm no chemist so I'm not sure if I can explain this correctly. This is how seachem explains the differing types of ammonia compound (and perhaps why the sensor is not indicating ammonia but the liquid test kit is, perhaps, only picking up on the less toxic ionized ammonia)...

"This kit measures total (NH3 and NH4+) and free ammonia (NH3only) down to 0.05 mg/L and is virtually interference free in marine and fresh water. Free ammonia is the toxic form of ammonia (vs. ionized Ammonia NH4+ which is non-toxic) and thus it is much more important to keep an eye on the level of free ammonia in your system. This kit is based on the same gas exchange technology that is used in the Ammonia Alert™ and thus is the only kit on the market that can read levels of free ammonia while using ammonia removal products such as Prime™, Safe™, AmGuard™ and any similar competing products. The other kits (salicylate or Nessler based) determine the total ammonia by raising the pH of the test solution to 12 or greater. At this high pH all ammonia removal products will breakdown and rerelease the ammonia, thus giving you a false ammonia reading. "

Hope that helps!
