I have a 35G corner and I want to know if a SEIO M620 which produces 620 GPH is too much for my small tank. I dont have coral and only 6 small fish. If its too much can you suggest 2 smaller heads I could use. ***Also wheres the optimal placement of a strong powerhead? and If I dont go with the SEIO wheres a good place for 2 smaller heads?
