I just ordered a turbo twist uv, and contemplating a hydor eth in-line heater and was currious as to how others have gone from the 3/4" fluval hosing to the 5/8" connections for the equipment. I know they sell reducing couplings but I'm having a hard time getting past the hose being ribbed and the restraints of aquariums in relations to adhesives. Any tips will be greatly appreciated.
