well Melissa and I have been changing from a 75 gallon RR to a 90 gallon RR. It has been a long process today. started at about 11:00 am and here @ 6:00 pm LR and water are in just waiting for the water to clear a little to put corals back in( they are in a LARGE plastic tote with a Maxijet 1200 for flow. hopefully in 2 hours it will bee clear enough to put coral in. when I figure out how to post pics I will.
