Will it suit my tank?
litres
Best for
A budget planted tank of roughly 60 to 140 litres where you want CO2 and heating hidden inside the filter.
Worth knowing
The maker warns to turn the CO2 off before unplugging, or water can back up out of the CO2 tube; as with any filter-mixed CO2, some gas can collect in the canister.
What stands out
- CO2 inlet and mixing chamber in the filter, cylinder not included
- Internal bay for a 22 to 24 mm heater keeps the tank clear of kit
- 3 or 4 media trays
- Touch-switch or pull-primer versions

Frequently asked questions
Quick answers about the Dophin CF11008 Series CO2 Canister Filter, drawn from its specs.
What size tank is the Dophin CF11008 Series CO2 Canister Filter good for?
Using the 5 to 12 times turnover rule for planted tanks: CF11008 (950 L/h, suits roughly 79–190 L); CF11308 (1,200 L/h, suits roughly 100–240 L); CF11508 (1,450 L/h, suits roughly 121–290 L). The maker rates the range for tanks up to 140 L. Real flow with media and hoses is lower than the rated figure, so pick the bigger model if you are between sizes.
