    So id just like to know whats the best way to make pipes leak proof for our fish tanks.

    can we use teflon tape? And ive heard that we can use tangit glue? Is silicone ok to seal woth or will it also get a leak in time?

    Pvc pipe you use pvc weld Tangit is good apply on both sides . pvc threaded pipe PTFE white plumbers tape dont be shy put plenty. Silicone is only for glass or poly pipe, on poly pipe which is black flexy pipe you heat the pipe and put silicone on the fitting insert into pipe and clamp

    Johan, depending on where in your setup you can use male / female connectors (they are PVC welded to the main pipes) add a O ring. When needed to remove just unscrew them .

    Used them in my previous setup

    I just use silicone on all my 50mm connections. If it is an overflow pipe it will not have pressure in it. So it is safe to just silicone it. For temp systems, this is 100%.

    Pipes from heavy pumps, like in closed loop systems, I think silicone will not last.

    When I started my first tank, all my overflow pipes were just pushed into each other. No glue, no silicone, nothing. Just pushed together. Had one place with a bit of salt creep, everything else did not leak at all. Maybe just lucky?

    The tape and silicone are good for a temporary setup but you should use the PVC long term. Don't be shy with it and push the two connections together and don't twist them together when you use the PVC weld

    Believe me, you will be surprised by how good silicone will glue it. I struggled to get a previous temporary set up dismantled. No problem with it. As long as you use silicone only on non-pressure pipes.
