Will it suit my tank?
litres
Best for
Anyone wanting a cheap canister with optional UV, from a 40 litre shrimp tank (CF300) to a large display (C2400).
Worth knowing
UV does nothing for algae growing on plants and can reduce some chelated trace elements if left on all the time; the C2400 is a big unit that needs cabinet space.
What stands out
- Seven sizes from 410 to 3000 L/h
- UV lamp of 5 to 9 W on UV versions
- Self-priming head with flow control
- CF300 mini canister for small tanks

Frequently asked questions
Quick answers about the Dophin CF Series UV Canister Filter, drawn from its specs.
What size tank is the Dophin CF Series UV Canister Filter good for?
Using the 5 to 12 times turnover rule for planted tanks: CF300 (410 L/h, suits roughly 34–82 L); CF600 (650 L/h, suits roughly 54–130 L); CF700 (750 L/h, suits roughly 63–150 L); CF800 (850 L/h, suits roughly 71–170 L); CF1200 (1,200 L/h, suits roughly 100–240 L); CF1400 (1,400 L/h, suits roughly 117–280 L); C2400 (3,000 L/h, suits roughly 250–600 L). The maker rates the range for tanks up to 500 L. Real flow with media and hoses is lower than the rated figure, so pick the bigger model if you are between sizes.
