Does somebody konws the good and bad sides of undergravel heaters? I
just received a book (Rataj & Horeman) with some words about this system
but can not make a decision.
What about undergravel filters? In this book, the show 2 different
systems, 1-a tray or plate that covers all the bottom oft he tank.
2- series of parallel rows of perforated plastic tubes.
I am setting up a 100 gl tank. (This will be my first aquatic plants
tank) Thanks for any help.
