so if i drill a hole in the top and silicone the cord from an submersible heater threw it and then fill and plug in should be ok? just asking because like everyone else wants to get rid of tank clutter and i just got a co2 reg so im trying to decide how im going to diffuse still
Can't tell you if it would be OK or not, only way to find out is experiment yourself. Give it a try and let us know how it goes. Myself I prefer the Inline Hydor so have no reason to experiment with this.
