Building my own python.

Yes tighten the clamps, but if the hose is to large for the barb you win not get a good seal.
 
like jericho said perhaps you dont have the correct size barbed fitting. but yes, silicone should solve your problem either way. and dont forget to tighten those hose clamps :thm:

I tightened the clamps until I couldn't move them anymore but there is still a very, very slow trickle of water. Would covering the connections in silicone help?

aquarium glue (which i believe is 100% silicone,) would work and not be harmful to the fish...
