i have a 27 gal refugium. i have at one end about two inches of the bottom the water inlet from the sump. at the opposite end about two inches from the water surface the outlet to the sump.
my problem is this it seems i have some stagnant water at the surface. it looks kinda like an oil slick. is this ok, will it hurt the biological filtration?
should i add a mini-jet PH (60 gph) to give some circulation.
my intent for the refugium is for biological filtration, but also for zooplankton to grow and thrive and i don't want too much current to mess with those guys.
thanks for the help
