Warr - Unfortunately, for you (and us) being reefers, MOST public aquariums are a bit of a let-down. Especially compared to what you see on this forum and in some fellow reefers homes...
BTW - you must PM me when you going to be here - we can perhaps get together for a drink one evening..... (PM me your contact no - I will call you).
BUT - saying that of the two oceans - it is still very interesting to go and see how they do things. Ask them if they can show you their surge device they use - HUGELY interesting....
