If the bulkhead will be used towards the bottom of the tank, then simply use an elbow pointing upwards in the bulkhead and then a standard slip Durso Standpipe can be inserted into the elbow.

I would expect to see a performance impact from the additional friction added by the elbows, I don't have a way to quantify this as I haven't personally tried it. The feedback I have gotten from people who have tried it is that overall it works well.

If the bulkhead is towards the upper part of the aquarium the results are not as clear, there seems to be a bigger performance impact. However, it seems to still work for lower flow applications.

Keep in mind you should still add a overflow chamber to protect the standpipe intake and reduce the amount of water that can drain in a power outage.
