Our advice: filter floss has to stay a mechanical filter

Don't wait too long to change it. And it isn't only about cleanliness — there is a mechanism behind it that most people never hear about.

Filter floss is fundamentally a mechanical filter: it catches particles, that's it. But leave it sitting too long and bacteria will colonize it. It becomes a biological filter. And those bacteria are precisely the ones that should be living in your biological media. They moved into your floss.

Then, the day you finally swap it — say after months — you throw your bacterial colony in the garbage and drop in a fresh, sterile pad. The result: an ammonia spike in a tank that had been running fine for ages. Worst part is, you won't know where it came from.

Floss changed often stays what it is meant to be: mechanical. And your bacteria stay where they belong.

Where your bacteria should actually live

• Reef Casa Bacteria Hotel Blocks — this is where the colony belongs. Each block gives you the equivalent of 20 lb of live rock in colonizable surface. A tank with a real biological base doesn't depend on its floss.
• Reef Casa Filter Media Bags — for your carbon or GFO, in the same chamber.

Fits your tank

• Reef Casa Cube 15 — 15 gallon all-in-one nano reef, 3-inch rear filter chamber.
• Reef Casa Studio 12 — 12 gallon nano reef.

Frequently asked questions

How often should filter floss be changed?

Reef Casa recommends 3 times weekly. That's what explains the pack size: 12 pads cover four weeks at that rate. Our advice: stick to it. Floss left in for weeks stops being a mechanical filter and turns into a bacteria substrate — which is not what it is for.

Do I have to cut it to size?

No. The pads arrive pre-cut to 76 x 76 mm, built for the filter chambers of Reef Casa aquariums.
