Oceanic, i also did my initial fill with tap. My tank has been up for six weeks now with no problems. I also had mine tested for phosphates and there were none. However, i do my water changes and top offs with RO
. Its only .50 cents a gallon at wallmart, and i change around 10 gallons at a time, so its only like 5 bucks a month, and you dont have to worry about your thousand dollar investment because you didnt want to get RO
water. I heard if your gonna do reef, you def. want to use RO
. Its your call really, i know of many people using tap without any problems, especially for initial fill. this is just my opinion however. Good Luck.
