1000EF+ Annual Service Kit - 9w UV Bulb, Floss, Coarse Foam & Carbon

A full year of media plus the UV lamp, in one delivery, sized for your filter. Mechanical floss traps fine debris. Coarse foam does the heavy lifting and holds your bacteria colony. Activated carbon strips discolouration and odour. A fresh 9w UV lamp puts the steriliser back to full output. Run all four and the filter does what it was designed to do. Important — do not change all your media on the same day The foam and bio media in your filter hold the bacteria colony that keeps your water safe. It takes weeks to establish and minutes to throw away. Replace it all in one go and your tank effectively starts from scratch — ammonia and nitrite climb, and your fish are the ones that suffer. Change it in stages: Swap no more than half your foam or bio media at a time Leave 2 to 4 weeks between changes so the new media can colonise Rinse anything you are keeping in tank water only — chlorine from the tap kills bacteria on contact Floss, carbon and the UV lamp are the exception. They do a mechanical, chemical or light-based job, not a biological one, so they can all be replaced in full Contains, all sized for the 1000EF+: 1 x 9w PLS UV bulb, 2-pin 3 x white floss pads 3 x blue coarse foams 3 x black carbon pads Cheaper than buying the parts separately, and it arrives as one pack rather than four parcels.UV lamp specification: Wattage: 9w Type: PLS, 2-pin Length: 163mm Rated life: approximately 9,000 hours When to replace the lamp: every 6 months where the UV is doing a sterilising job, or every 12 months for green-water clarification. UV output falls away long before the lamp stops lighting up, so a lamp that still glows can be doing almost nothing.Fits: 1000EF+ external filter with 9w UV only.
