As for the tub, this is one that has NEVER been used. No cleaning products or nothing. just ran water through it occasionally. I also checked with a test later using 4 glasses I got straight from the kitchen sink.
All 4 tested to have zero ammonia when I tested them initially after pouring the water from the faucet into the glasses. Then I doused two of the glass with prime. Re-tested an hour later. The two doused with prime showed high levels of ammonia at over 5ppm. The ones not doused with prime showed zero levels of ammonia. Just to check again, I took the two glasses not doused with prime and showing zero ammonia after an hour aside. I doused one with prime and left the last one untouched. Tested those two an hour again. Want to guess the results? Prime doused water showed high levels of ammonia and the non doused one showed nothing.
That only proves chloramines in my water. And yes, chloramines will kill fish. Even after doused with prime, the ammonia left over, while not as toxic is still toxic and will kill fish. What makes it worse is how hard and akaline the water is here. Which can undo what prime does to the ammonia which is to ionize it. Luckily the rosie reds I have in the tank don't seem to care so long as I keep using a bit of prime everyday to keep the ammonia locked in ionized state. They seem to be healthy, swimming around just fine, eating and pooping like crazy. The other tank a couple of the fish died even though it has a partially established bacteria colony due to the chloramines. So I've started to switching out the water with small water changes for reversed osmosis water. I don't want to do too much because of the massive PH difference the fish would be subjected to. However, after even a little water change I can see they are reacting much better. I'll have to continue with that until I can get the tank mostly free of that nasty tap water we have here.
