Use a gasket or silicone in a similar fashion as mentioned above to connect the lower lids to the tubes. Fill the trough as mentioned in the steps above but instead of letting the material dry, press the cylinder into the lid, clamp together and then leave to dry (24 hours ideally). The silicone can be smoothed out with a gloved finger. This also reduces the surface area for bacteria or dirt to attach too. The water pressure is highest at the bottom of the filter, and so fusing the tube together with the lower lid is a good idea since it makes the seal extra strong.
