Marineland Bonded Filter Pad (312 sq in)
The cartridge-killer: a big bonded floss pad you cut to fit any filter, for pennies compared with branded replacement cartridges. Pure mechanical polishing.
- +Universal — cut to fit any filter, so one 312 sq in sheet replaces dozens of proprietary cartridges
- +Dense floss gives fine polishing and doubles as a mechanical pre-filter to trap debris
- +Dirt cheap — the lowest-cost way to keep water clear, versus a monthly cartridge bill
- +Trims to fit most HOBs, canisters and sumps
- −Traps so much debris it needs rinsing or swapping every few weeks
- −Sheds a little lint on the first rinse
This is a Marineland Bonded Filter Pad, a 312 square inch sheet of bonded floss you cut to fit any filter for mechanical polishing. One sheet replaces dozens of proprietary cartridges for pennies.
- Fine mechanical polishing in any filter
- Replacing expensive proprietary cartridges cheaply
- A cut-to-fit pre-filter to trap debris
- Biological filtration, which needs bio media
- Chemical removal of tint or medication
- Anyone wanting a long-life reusable medium, since floss is largely consumable
We separate what the maker claims from what independent sources confirm, what owners report, and where we are drawing an inference. We do not bench-test products.
- Bonded fine-and-coarse floss for mechanical polishing
- One 312 square inch sheet, cut to fit any filter
- Doubles as a mechanical pre-filter
- Pure mechanical media, not biological or chemical
- Traps enough debris to need rinsing or swapping every few weeks
- Well rated; sheds a little lint on the first rinse
- The cartridge-killer: cut-to-fit floss that ends the monthly cartridge bill and polishes water clear
Dirt cheap versus branded cartridges. It traps a lot of debris, so rinse or swap it every few weeks; it is largely a consumable, though it rinses a few times before it packs down.
- Leaving it until it clogs and reduces flow
- Expecting biological filtration from it, which it does not provide
- A little lint on the first rinse if not pre-rinsed
We do not bench-test this; the assessment synthesises the manufacturer's stated specification and aggregated owner feedback. We give gear and method guidance only. For a fish's specific health or diet needs, consult a veterinarian or an established authority.
You can rinse it a few times, but bonded floss packs down and is largely a consumable. It is so cheap that swapping it is not a burden.
Yes. Cut it to your filter's size and it does the mechanical job of a proprietary cartridge for a fraction of the cost.
Some colonises any surface, but floss is mechanical media. Keep dedicated bio media so rinsing or swapping the pad does not disturb your cycle.
