hi guys i have a ?. well ever since I've been in the hobby I've been using quiet one pump 780 for my 55g reef tank as my main pump, i really love the pump because it use low watt and produces little heat i have it connected to a scwd with 2 returns . everytime i turn the pump off to do a water change it takes me for ever to get the pump to start again i even soaked it in vinegar, also my scwd is stuck on one side, any way i would like to know if i should get a eheim 1260 or 1262 remember I'm goin to run it with a scwd with 2 returns . im plannin on puttin the scwd with some vineger , i have 3 yrs with it and this is my first maintenance if it doesn't work then ill get a new one . sorry for l the writing.
