Breaking Down the Tank-Need Advise
Actually, Steve advised removing the polyster layer. I’m still keeping that message 
He wrote: “With the layer of glass wool between the gravel and the UGF (UnderGravel Filter), the health of your filter becomes problematic. Eventually, that layer will become clogged, and there is no good way to clean it without completely removing the substrate and replacing it. The failure of this layer will probably take some time to be discovered, which will not be good for your fish. When it is convenient, you should remove this glass wool from your set up.”
I’ve had serious problems with fish health lately, although I’m doing more than one PWC aweek, so all I can blame is that polyster layer, it should be already clogged as the tank was set and overstocked for almost a year.
And I DO have a power filter, I explained in my message. The two internal and UG filters are up and running with power heads.
