This is going to sound like a really odd question, but having trouble deciding what to do. I recently acquired a 150 gallon with some plumbing, which includes overflow plumbing. My problem comes in order to use the most I can I had to get a 1/2” adapters for part after the bulkhead, I’m worried that it might restrict the flow too much and I’ll have to end up redoing it all once I do a wet test. Will it not be as big of a problem as I am thinking? Should I just scrap it all and redo all of the plumbing, bulkhead included? I would have to wait for shipping if I do it that way. Advice is much appreciated.
