flow in a refugium

295 from a MJ1200 coming into the HOB Large fuge and a small PH for circulation inside the fuge to remove deadspots
 
Hiep, how you doing bud, I was checking out your web site but it wasnt there anymore what happen ?

Anyway, in the fuge you want to have good water flow, not as much as your sps tank, but if you dont have good flow, you will get red slime algea
 
I turned a 20L into a refugium and have been running 200GPH through it with great success. The water has to be in the refugium long enough to be effected by the natural filtering process. I also keep a coral banded shrimp and a small damsel in there to eat any food matter that gets sucked through the overflow, a filter doesn’t do much good if it just becomes a home for rotten food.
