hello all, this is my first post in the forum so stay with me here. i currently have a 20 gallon long fowlr. looking to turn my 55 gallon cichlid tank into a reef. i would like to drill the tank for bulkheads and returns. i would like a bulkhead on the left and right side draining into a 20 gallon long sump with the return drilled into the center with a flexible y output. my question is what size bulkheads would be sufficient and what size return pump would go with that. thanks for all the help!!
