This looks interesting, would think about putting at the end of tank, 40B, what about noise? Are these made to move water around. How would this compare to other types. (Glass inflow ones with that strange shape.)
I read some reviews, and someone said that they drilled the holes a litter bigger. What's your thoughts on this?
I also might have to get a heater at some point, will that spray bar move water around the tank? (Small Discus?)
