i would say 20% water changes every day and have a look around for somthing rotting away in there, do a good gravel vac,
When you move the gravel about do you get bubbles rising up?
with the water change that I'm doing now I gave the gravel a good dig around with my fingers, not one bit of gravel is left untouched. the gravel makes the water go a misty whitish colour but no bubbles.
Thanks
