I am going to move my mp40 in the 34g to the opposite side and have it face out to the front instead of on the side. I am doing this to even out the flow since I have the stock pump and wp10 on the same side and noticed a few slow/dead spots on the opposite. Have you ever had an issue with moving a pump? I'm aware of the obvious instant effects if its bad, but wanted to cover all bases. I realize it will be a big change on the coral and want to prevent all the extra stress I can.
