Hi Nanman,been keeping for a few years now and have only just shut it down.Like you've heard marine tanks are very very different to freshwater tanksthis is a good link, otherwise is too much to go through in 1 thread. - http://www.masa.asn.au/masawiki/index.php/Beginners_Guide and also think about joining the local club MASAOG, a great resource for someone wanting to get into the hobby - http://www.masa.asn.au/masa/masaog best advice is the more knowledge you have the better equipped yopu will be to care for the critters. be very careful though as our local marine species are temporate and so
