So I want to change the inside part of my overflow because I hate it, the box on the outside is fine I guess but the overflow “screen” drives me nuts, so my question is how can I change this to a normal overflow box? Is t possible? The drilled hole is 1 1/2 inches o just want a box inside my tank draining into the other box on the outside, I’ll post photos of what I have as my overflow currently, I have it plugged with one normal drain and 1 emergency drain
