I'm looking for opinions on undergravel trays and powerheads for a freshwater tank. I was highly suggested them at my lfs, so being a begineer I thought that they were a must.
The more I've learned, I've seen a lot of opinions that say they're at best a useless feature & have the potential to harbor a lot of filth and disease.
So please, any opinions or experience with undergravel trays and powerheads?
