Hi...Is that the test kit with Doc
Wellfish on the box? I have this test kit for ammonia too. Mine is about a year and a half old. I couldn't find an expiration date on the box.
My tank cycled fine, and my fish are ok -- no signs of stress or anything. But the last few times I did the test, I read a small amount of ammonia -- probably between 0 and .25. The water in the tube was not yellow, but it wasn't as greenish as the .25 reading either. I went to the lfs
to get another kit. They didn't have the Doc
Wellfish brand (well, they did, but it was the Nessler kit and I wanted the salicylate test. The boxes looked exactly the same! It's a good thing I didn't confuse them!) So anyway, I got a Jungle test strip ammonia test. I heard that they are not as accurate as the test tube type kits. I just got one to check the results of the (old) Doc
Wellfish ammonia kit until I can get a new one. Guess what...the Jungle test strip is showing 0 ammonia. So, even though the Doc
Wellfish kit has no expiration date, I think my old one isn't useful anymore, and I'm going to get a new one.
P.S. what is a pl*co? Does that mean pleco or something else? I've seen this in other posts too. OK, there's my dumb question of the day!!
