Wave pumps

[MarkG]

New to this , my question is I have a Fish only 75 gallon reef ready tank.
I have two pumps going that switch from one to the other every 1minute.
Do I need them in my tank,do I need two or can I get away with one . Any thoughts on this.
Thanks for the help .

Flow is good to keep oxygen in the water, especially if you have one or both pointing towards the surface. I would keep both.
