Full Spectrum Chemical Filtration In Convenient Pad Form PURA Filtration Pads offer the same broad-spectrum filtration capabilities as PURA Complete in a simple to use filtration pad form. In addition to heavy-duty chemical filtration, PURA Filtration Pads offer the finest mechanical filtration of any pad. Made from a carefully selected thermally bonded blend of polyester fibers, these pads offer very fine filtration while resisting clogging. The most frequent comment we hear from our customers is that their tank has never looked so crystal clear. In tanks with high levels of pollutants the granular media should be used to bring down the pollutant concentrations and then the pads can be used to permanently maintain low pollution levels. These pads are ideal for wet/dry drip trays, canister filters, power filters, and as supplemental chemical filtration in Eclipse systems. There is no finer filtration for a Nano-Reef! And that is the main reason we make this available to use on all of our nano packages. PURA Pads can be cut with scissors to fit any application. These pads are made from ultra pure ingredients and do not contain any glues, binders, adhesives, or ash slurries. PURA Pads last longer and remove more pollutants than any other filtration pad. *THIS IS THE XLG. SIZE PAD AT 15"X30".
