I used to have a 100 gallon saltwater tank.I had 2 clownfish, 1 sea urchin, and some live rock. Everything was going good for about 3 weeks. I came home and i notice brown algea (Diatoms). Once i started geting the brown algea out i had to replace the water. After that my water level was always low from evaporating from the sump. I stop the saltwater tank because i could not buy more salt. Now i am going to build a 75g reef tank would a magnium 350 be good enough for a filter? How many watts do i need for a reef tank (75g). Also would it be harder to maintain,
