Fluval BioMax Bio Rings (500 g)
$19.99
Ceramic ring bio media with a porous internal maze for fast bacterial colonisation. Universal, well-priced and reusable — a proven default for any filter.
Pros
- Porous ceramic rings with high surface area and an internal pore network for biological colonisation
- Ring shape lets water flow through the media rather than around it
- Rinse and reuse for a long service life; washable and does not break down quickly
- Universal — works with any filter, and you cut the amount from the bag to fit
Cons
- Fluval suggests replacing rings about every 6 months, though many keepers rinse and keep them far longer
- Rings are smaller than Matrix, so raw capacity per litre is a touch lower

$9.19 · 92 / 100A+
A rechargeable synthetic resin that polishes water to a sparkle and pulls out organic waste before it becomes nitrate. Bleach-regenerate it and reuse — not a single-use carbon.
$11.46 · 90 / 100A
Classic bulk activated carbon for removing tint, odour and leftover medications. A jug this size refills a hang-on-back for a fraction of the cost of branded carbon cartridges.
