I am doing a 72 bow front ( I know not a popular choice, but it was my fathers who recently passed away). I have a 20 gallon sump. The sump will have a sock on the water in line and the skimmer will be in that same compartment, the next compartment will be a refugium, and the final will be the return. I am looking for a good skimmer for my size tank, that doesn't cost 748495928476 dollars. Any suggestions? Space is not a huge issue as I have not installed baffles yet, but smaller would be nicer
