So in my experience in reefing, I have never messed around, researched and have little knowledge in plumbing a tank. The tank I am about to set up is only going to be set up for a year to hold me, until we move and get a new house and set up a red sea reefer xl, but for now I want to set up a 75 gal and get back into the hobby. I have no idea where to start. Ive been buying equipment for the future tank now trying to save money and I have some of important equipment that I think I can use for the 75 and the future tank so two birds with one stone. So what I have now that I think I can use for the 75 gal non reef ready is a sicce syncra return pump 5.0 adjustable flow, SRO 2000 int and what I believe is around 20 gallon tank for sump. I dont know where to begin. I do not want to make this a very expensive set up as this is only suppose to hold me for a year, year and half or until we get a new house which is still very debatable and will be awhile. As far as plumbing I do not know what to do. What do i need to buy to complete the set up, should I get an external overflow, how do I build my sump for the return and skimmer, how do I plumb the tank, what path is best for my goals? If you have any knowledge or tips please share. I really just want to have this 75 gal with the 20 sump running with minimal expense, maintenance and use the equipment I already have for skimming, return part, other necessary parts and buy as necessary for plumbing.
