Frequently asked questions
Quick answers about the SunSun HW-700 Series Canister Filter, drawn from its specs.
What size tank is the SunSun HW-700 Series Canister Filter good for?
Using the 5 to 12 times turnover rule for planted tanks: HW-702 (1,000 L/h, suits roughly 83–200 L); HW-703 (1,400 L/h, suits roughly 117–280 L); HW-704 (2,000 L/h, suits roughly 167–400 L). Real flow with media and hoses is lower than the rated figure, so pick the bigger model if you are between sizes.
