Hey,
I'm not sure if this will work but i'm gonna give it a try!
You comments are welcome.
The idea is to put the heater inside of this contraption!
The output of the canister filter will attach to the bottom barb,
the heater can just sit right inside,
the top will be open so I can pull the heater out easily to adjust it!
What do you think?
Will the water spend enough time around the heater for this to work?
Here is some pics,
Parts (sorry I already assembled a couple pieces)
Here is the whole thing together,
Here is how it will look on the tank
(this is not the tank it is going on, I just placed it on the front of this small tank for a pic!)
