[shaunpp]

im a newbie here and on keeping a marine aquarium. i use to have a 500 litre south american cichlid system but have now decided to clear out and change to marine. very excited and hugely interested but need a little help to get me started slowly very slowly i have decided to go for a small reef only system to start and then slowly introduce fish probably next year. i have sort of planned out a sump copying a few ideas off other people and come up with this the drawing is roughly a 3rd of actual size and proportions are roughly correct. can any one steer me in the right direction and correct any mistakes any help will be much appreciated.
