Not a lot of info here, but I wonder how much water you changed and if you use an additive when adding water. I have found that my fronts need frequent water changes, but they do not seem to do well with anything more than a 25 percent water change per week. I actually have started feeding less and change about 20-25 percent every couple of weeks.
What do you feed them?
What are your parameters?
Any pictures?
How often do you change the water?
I would pick up a test kit (drops) instead of test strips. Get some good data to work with and keep an eye on your parameters. I would also talk to your lfs about your tap water as well.
What does "ph is fine" mean? If you test ph it could read "fine" but that doesn't always mean it hasn't fluctuated.
Good luck.
