I believe that the Eheim stats on the chart for gph are incorrect. According to their site, Eheim's stats for the Professional 3e (2078) are 1850 l/h, and that converts to 488.7 g/h, according to an online conversion calculator. The Pro 3e has variable flow rate settings, but just comparing that 488.7 g/h to what the chart says, "88-242 g/h", something is amiss.
I have a 75 gallon tank filled to about 70g and this one filter cleans it really well, biologically and solid waste. I have two 4-5" RESs and over 30 fish, plus plants whose leaves keep the filter's intake basket challenged all the time
. My point being, I doubt the 88-242 g/h is correct in the chart or I'm missing something.
