Following Nick. We have a lot of similarities including ostreopsis and moving tanks. I will be moving this Summer and have thought of selling off my RSR250 and restarting with a frag tank. I've thought about drilling an aqueon just like you did but was thinking of drilling from the bottom and having an in tank overflow. I'm also strongly considering going back to T5s and I have an ATI fixture laying around thankfully.
Let me know how the modular marine overflow is sound wise!
