So I am working on an 87 gallon tank. It comes with a 1/2 inch return pump and 1.25 inch drain holes. I am putting an adapter to use 3/4 return pump. The drain, I am doing a durso stand pipe. The over flow box looks ridiculous with a huge 1.25 PVC durso stand pipe. Should I get an adapter to make it smaller to 1 inch or so? On my current tank, the drain is 1 inch and it has no problem tanking the drainage from the 3/4 return pump which is a tunze 1073.40 that pumps about 700-800 gph. Also, should I lower the neck of the durso a bit. I raised it high to cut down the noise. Experience gained from the current tank Thank you in advance for your feedback.
