I ordered a Hydor Mini which should be coming in tomorrow and was wondering if anyone knew whether it would be better if I buried it in the gravel or if I let it dangle. The bowl that I have is a 2gal and it's plastic/acryllic (not entirely sure which). I'm just kinda worried that the heater might somehow warp the plastic if I bury it in the gravel and it ends up touching the bowl itself.
Also, if it won't damage the bowl, could I forgo the gravel and just put the heater on the bottom? The bowl that I have is a major pain to clean when there's gravel in the bottom...
Thanks!
