You want very slow flow through your
UV and very fast flow through your tank. Your tank should turn 10-20 times AN HOUR, so turning your tank 2.5x a day, while it may be good for your
UV will not support your tank properly. I have my
uv on a loop out of and back into my wet/dry and then a return pump from my wet/dry to my main.
HTH!
