Biocube 32 upgrade dilemma

[tdubs]

So, I upgraded my return pump to a similar output DC pump by Hygger. I love the pump, it is completely silent now. I am swapping out the return head for a dual nozzle design with the intent of having one head used to break surface tension and the other to provide flow.. Now I would also like to upgrade the pump to the next sized Hygger which is 660gph, almost twice the output of the factory pump-

My question- will the return chambers be able to keep up with the demand of the pump or I am going to cause too many issues by doing this? I have heard of people sawing off some of the grill intake pieces to compensate for the increased demand.. I really don't want to physically modify the tank.

Thanks!

My first question is why you want a return water flow which gives you a water turnover rate higher than 20 times per hour?

I do not know Hygger´s pumps but DC pumps use to have a controller there you can adjust the flow the way you want. The ones I know normally allows you to vary the flow between 30 - 100% of the maximum flow.
