Re: Seachem Ammonia Alert

I've heard from several people who have used them with success, and a couple who had faulty disks.
Things to note would be that they only measure TOXIC ammonoia, most test kits measure total ammonia. Toxic ammonia is normally only a very small percentage of the total but its the bit that you really have to worry about.
I wouldn't rely on it as a replacement to normal water tests, but it does offer peace of mind.
