High Phosphates

[ovrmyhdagn]

How can I get my phosphates down? I already do partial water changes and I still have 1.0 phosphates.

Do you use RO water? How many, and what fish do you have in what size tank? How old are your lights, and what type of lights are you using?

I use RO water. I have 5 fish in a 75 gallon tank - juvi emperor, 2x black and white clowns, flame angel, foxface.
I run PC lights 220 watts (2 10k 55 watts, 2 blue 55 watts bulbs), the light system is 2-3 years old.

Run some phosphate remover and some fresh carbon. For the future, a refuge with macro algae would help greatly if you do not already have one.
