Finding a mysterious leak in filter...
I have noticed recently that there's a small leak in my filter cabinet. It's not leaking a lot but there's a small puddle in the cabinet every few days. When I feel around the filter and the diy bio filter, I can't feel any moisture on either.
I feel like it should be coming out of the bio filter because it's made out of a house filter and being a DIY job, I just figure it's a mistake somewhere on my part. The thing is, the setup has been running for 6 months without a problem. I've only noticed it in the past week.
But, before I tear everything down, does anyone have an idea of how I can isolate the problem?
