If you opt for the HOB
type I would recommend make it yourself from PVC
. A PVC HOB
will cost you about $15 max while a store bought HOB
will cost about $40-$80 depending on the size of your tank. I have a PVC HOB
on my sons 55g and it has never lost syphon when power has gone out, an it takes up way less room behind the tank than a store bought box type HOB
. Just my opinion though...
