Hello. I am recently getting back into the hobby after about a 12 year break. I just purchased an IM 150g lagoon tank and a bashsea 36” sump. I have never plumbed a tank before so I have been reading articles here on this website as well as watching a lot of online videos. I feel like I have learned a lot and have started to make some of the plumbing purchases as well. The return pump I purchased is a sicce 9.0 which has a 1” return outlet. I noticed that my tank has 2 3/4” returns on the back. I thought I had read that you should not go from a large outlet to a smaller outlet on your return, or is this ok since it is going to split from the single 1” to two 3/4”? Hopefully how I explained it makes sense as I am still new to plumbing. Thanks for any help!
