So now the question is, do you have a sump or do you need a skimmer to hang on the back of your tank?
if the question is should I/ you(or anyone) have one. the answer is yes
now, if the question is do I
then i have to say yes on some of the tnaks i take care of. and no to others
as for the remora HOB. they are a great skimmer and i would reccomend one to nearly anyone who has a tank within their capacity. however, i would and do reccomend upgrading the pump from the rio to the mag.
