Product Description
Function -137s
The Aqua One 137s Blue sponge pad is designed solely to fit the new Ocellaris 850 and 850UV compact external canister filter. The 137s acts to collect solid waste (thereby preventing the finer 138s and 137w being blocked prematurely) and alsoprovides a culture medium for essential aerobic filtration bacteria
Effect on Flow Rate
Because the 137s is constructed from quite fine sponge it will reduce the flow rate of your Ocellaris 850 and 850UV when blocked and dirty. Reduced filter flow rate can be catastrophic for aquarium water quality. The solution is thankfully simple – just replace the 137s as required.
Lifespan
The 137s should last several months of average use and may be rinsed in a little aquarium water at filter clean out time (the dirty water should then be discarded). Older 137s sponge inserts tend to let more debris through than is ideal, for this reason we suggest replacing it every four to six months.
Pack size
Two 137s are provided per pack. Making a pack last between eight and twelve months. Heavily stocked aquariums may shorten this life span – do what is required to keep you Aqua One Ocellaris 850 and 850UV filtering effectively.
Use With
The Aqua One 137s Sponge Pad works best with the Aqua One 137w Polymer Wool Pad, the 138s black sponge pad and, of course, Aqua One’s Bionoodles 600g. Inserting a bag of Aqua One’s Advance Carbon 450g between the 137w and the 138s black sponge pad in the top filter tray can bring large benefits in terms of clearer, odour free aquarium water – well worth doing in our view.
