i just bought a new fluval roma 240 tank and it comes with the fluval external 306 filter. when speaking to the guy in the local lfs he said i should put sealent/ silicone (which he gave me some of) at some of the fixtures connecting the external filter to the tank but i can't remember what ones, he said this would help if any leaks were to happen.
if anyone could give me some advice this would be helpful as really stuck and not sure if required or not. Only ever had internal filters
