125g saltwater set up help

wow! thank you so much for your help guys, I have always like my aquaclears but then again with that tank it was simply just cichlids, as I use to be really big into them, SO yeah now its a whole different ball game all together, as far as my buget goes well, I never like to stinch out, but then again have to stick with what I can afford, so hopefully I can buy it all peice by piece and by the time spring comes I can have MOST of all the important stuff I need,
