Quick answers about the SunSun JS Three-in-One Top Filter, drawn from its specs.
Using the 5 to 12 times turnover rule for planted tanks: JS-400 (350 L/h, suits roughly 29–70 L); JS-600 (650 L/h, suits roughly 54–130 L). Real flow with media and hoses is lower than the rated figure, so pick the bigger model if you are between sizes.
