Juwel's own recommendation is to replace them every time you change a tube — they are rubber, they take heat and condensation, and they are the part that quietly stops sealing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReusing tired caps is the usual cause of water getting into a light unit.\u003c\/strong\u003e A new tube in old caps is a false economy: once water is inside the unit, the tube is the cheap part of the repair.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChoosing a size — measure the tube, not the tank\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e16mm\u003c\/strong\u003e — T5 tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e26mm\u003c\/strong\u003e — T8 tubes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOrdering by aquarium model is the common mistake here, because the same tank could be built with either.
