Dophin CF‑300
Flow rate: ≈ 410 L/hour
It’s sold as a “mini canister / external filter.
Suppliers often list it as suitable for “small tanks,” “plant/shrimp aquariums,” or small freshwater / marine setups.
What typical use‑recommendations suggest
Many sources and retailers recommend the CF‑300 especially for smaller aquariums (e.g. up to 40–50 L).
For a 100 L tank, a generally recommended flow rate (for adequate turnover) is ~ 3–5 × tank volume per hour — meaning 300–500 L/h.
At 410 L/h, the CF‑300 is on the lower end of that band, which means it could work — but might struggle with heavy fish loads, lots of waste, or a densely stocked tank.
What that means for your 100 L tank
If your 100 L tank is lightly stocked (e.g. a few small community fish, plants, or shrimp), the CF‑300 could likely manage — but it’d be near its upper comfort zone.
If you have many fish, large fish, or a “dirty” tank — or if you plan heavy stocking — the CF‑300 might not be quite sufficient. In that case, you might want a stronger filter (higher flow + larger media capacity).
