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).
GRECH PUMP CQB-6000 - 5800 L/H
The CQB-6000 is part of the “CQB series” multi-purpose submersible pumps from GRECH.
It is rated to deliver up to ~ 5,800 litres per hour (L/h) flow.
It also has a maximum “head” (vertical lift) of around 4.0 metres. This determines how high the pump can raise water while still providing that flow.
The unit is typically designed for submersible use — meaning it runs underwater.
The pump housing is often made from durable ABS-plastic, and it features a wear-resistant ceramic shaft / impeller (or similar) — which helps with longevity and resistance to wear.It’s described as usable in both freshwater and saltwater environments, which makes it versatile (ponds, aquariums, fountains, water features, hydroponics, etc.) depending on how you set it up.
Typical Uses
Because of its flow rate and submersible design, the CQB-6000 is commonly used for:
Ponds, water gardens, or water features/fountains — its high flow and head make it suitable to circulate or lift water even if there’s some vertical height or distance involved.
Aquariums or large freshwater/saltwater tanks — especially where significant water circulation or pumping is required, e.g. return pumps, filtration systems, sump-to-tank setups.
Hydroponic or aquaponic systems — where water needs to be circulated or recirculated through growing media or systems. Indeed, GRECH markets their “multi-purpose submersible pumps” for this kind of use.
Fountains or decorative water flows — if you want a strong, reliable flow for a waterfall, cascade, or water feature.
Strengths
High flow and decent head — so it can handle medium-to-large ponds or tanks, or systems with some vertical lift.
Durable build, thanks to wear-resistant parts and robust housing — which helps for long-term use.
Versatility: compatible with fresh and salt water; suitable for multiple applications (pond, aquarium, hydroponics, fountains).
Submersible: easier installation since the pump goes in water, and no need for complex external plumbing.
What to Watch / Consider
Because it’s high-flow, you’ll need plumbing (hoses/pipes) that can handle the volume — too small pipes will reduce efficiency or overload the pump.
If using for aquariums or living systems (fish, plants), ensure that the flow rate and water movement is appropriate for the inhabitants — too strong a flow might stress fish or disturb substrate.
Regular maintenance may still be needed — especially cleaning the inlet/prefilter and ensuring no debris clogs the impeller (many pumps allow particulate up to a certain size, but performance degrades if clogged). The “open-type centrifugal impeller” design (found in some similar pumps) allows dirt up to some size — good for ponds/fountains, but maybe less ideal for delicate aquarium setups.
Ensure the power and electrical supply matches — submersible pumps must be properly insulated and grounded, especially if used in a saltwater environment or outdoors.
Is it a Good Fit — when you want this
The GRECH CQB-6000 is a good choice if you need a strong, reliable, submersible pump for ponds, large tanks, hydroponic systems, or fountains. It’s more than sufficient for medium-large setups, and robust enough for continuous use, provided you handle plumbing properly and maintain it. On the other hand, for very small aquariums or very delicate setups (e.g. gentle flow for certain fish/plants), it might be “too powerful.”
