tank is gonna be 1.5mx1mx600mm(dept).would like to keep a mix of corals and fish.
then that would be the T5 unitGo Geisemann all the way.
Or you can go the ATI route. The bulbs are excellent and they are used on some of the best tanks I have seen
From what I have seen, yes, ATI is the way to go. Also, if $$$ isnt an issue, go for the ATI Power ModuleSo what you are saying ATI is the way to go...
