Well I have been doing a lot of research and the people at my saltwater lfs (very reliable and family owned!) say every 2 weeks, they also say if nitrates go over 50ppm do a water change. So 50ppm is the limit unless you have coral which means the nitrates should be 0ppm but no higher then 5ppm. As for the amount they recomend 10-20% if you have liverock and 25-35% if you don't have liverock. I hope I haven't confused you lol

What is the nitrate level in your tank?

wondering is the beauty of mystery
Check out my 29g grow out (quite a mixed bunch)
