For PAR planning, use the performance chart published for your specific fixture rather than the bare tube figure. As general practice across T5 HO brands — not a figure Aqua Medic publishes for this specific tube — the blue end of the spectrum that corals use falls away well before the tube stops lighting, so most reef keepers replace T5 tubes on a schedule of roughly 9 to 12 months rather than waiting for visible dimming.\u003c\/p\u003e\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWipe the tube and reflector free of salt creep regularly — a dusty reflector loses more output than an ageing tube.\u003c\/li\u003e\n\u003cli\u003eReplace on a schedule rather than waiting for visible colour shift or failure.\u003c\/li\u003e\n\u003cli\u003eLet the tube cool before handling after use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\u003cp\u003eCovered by Aqua Medic's standard manufacturer warranty against defects, in addition to your rights under Australian Consumer Law.

Fitting the wrong length isn't physically possible in most fixtures, since the pins won't reach.\u003c\/p\u003e\u003ch4\u003eWill this tube alone light a reef tank properly?\u003c\/h4\u003e\u003cp\u003eIt gives a clean 10,000K daylight spectrum, but most reef keepers pair it with an actinic (Reef Blue) tube in a multi-tube fixture rather than running it alone, for the blue wavelengths corals respond to.\u003c\/p\u003e\u003ch4\u003eHow do I know when to replace it?\u003c\/h4\u003e\u003cp\u003eA T5 tube keeps lighting long after its usable spectrum for coral growth has dropped off. Replacing on a set schedule — commonly every 9 to 12 months — rather than waiting for visible dimming is standard T5 practice.\u003c\/p\u003e\u003ch4\u003eDoes it fit non-Aqua Medic fixtures?\u003c\/h4\u003e\u003cp\u003eYes.
