Thanks Caryl & Peter
:oops: No, I didn't remove the uneaten peas I thought I could leave them. I can't say for sure if there were any left when I changed the water. When I give them to my goldfish, I always "smosh" :roll: them up & I did the same here, but honestly I can't say for sure if I would have missed breaking one up
Peter, what was happening started before the water change. Yes, our water contains chlorine & chloramine. I have copper pipes but I emailed the company that makes the, uh :-? stuff, that I add to the water for the chlorine/chloramine and asked them about the copper pipes and they claim it makes the water safe.
The pH test kit only goes as high as 7.6. I do find it hard to tell the exact measurement, that is why I usually say between 7.4 & 7.6. But, it never varies, I might be a bit off with my judgement :-?
I am at a loss as what to do. They're behavior is still the same
