I am putting a tank together and I think I want to add a VorTech powerhead. I cant decide if I should get the MP10 or the MP40. The tank is a 40g Breeder (36x18x16) its will be a mixed reef so I am not sure how much flow I should have, I will already have around 8-10X from my return pump. I would rather get the MP10w to save some money but by itself it may not be strong enough. I do have a Jebao WP-25 (I think its a 25) that will be in as well. Do we think this would be enough flow in the tank to have the MP10 at 75-80% and then the WP-25 on as well? Or would 1 MP40 suffice? Either way its gonna put me in the dog house with the wife :spin3:
