ok I bought a used 125 Aqueon reef tank with complete setup. I am taking my time to reconstruct, clean, and make mods that I want. Here is my question I just noticed the durso pipe has some drilled holes right at where it bends at top. Is this right? If I look at it then water would drain thought the holes and not come up wher the cage is. Attached is picture. Also the two returns under neath use 3/4 inch. The returns drain down where cionnected to 1 inch flexible tubes. So questioning flow rate
