I am new to this site also new to salt water set up. I have a 90gal not RR but want to make it that way, how ever this is my set up as of now....1"over low with 3/4" return,with a 37"X15"X16" custom sump, first stage 11X15 second 14X15(refugium) third 6 X15 this sump has a bubble trap. First question..is a mag 12(as pump) a return sufficient for the flow i suppose to have? What should be my flow for my tank? What is a good skimmer for the 90 gal(i had my eye on the aqua C EV 180 is there something better but less expensive)? what tank/sump light should i get?(going do mix coral)that where i am at now, if some one can help to point me on the right path. The reason i seek experience help because there is a lot of equipment for this hobby i did research but as a novice to this game every thing can work. Thanks your help is greatly appreciated.
