does anybody use an eheim pro2 2028? i got mine 2n hand and dont know how to interpret the maintinence/flow indicator. its just a little window where the intake hose clips in with 3 horizontal green lines on it. ok complete thicko question i know but what does this mean. is it the green lines disapear as flow is reduced ? no doubt when somebody answers i will slap myself lol
