hello everyone. i have a fluval spec v, it is a 5 gallon with a built in "sump". the return pump isn't too strong, as i have had my seahorses for a year in there with no problems, but if they do get caught in the flow they get tossed around. i am now having an issue with the top of my water looking oily, so i was looking for any suggestions for building a spray bar or something to calm the flow down a bit. i also have a hang on refugium, so i am not quite sure why the top of the water is looking oily. from previous experience it's from stagnant water/not enough flow, but that can't be the cause because i have two return pumps that create good circulation. any suggestions?
