Quick answers about the SunSun JP-09 Series Internal Filter, drawn from its specs.
Using the 5 to 12 times turnover rule for planted tanks: JP-092 (250 L/h, suits roughly 21–50 L); JP-093 (450 L/h, suits roughly 38–90 L); JP-094 (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.
