How often are you changing it now? Ever measure the phosphate in the effluent? At high levels it can deplete in a day.
Which problem specifically?
I'm changing it at every other water change (every 4 weeks exactly) because that's what it recommends on the container. Should I just try to change it at every water change (2 weeks)?
Well I guess I assumed the problem (hair algae, lightening of sps) was all related to phosphate levels being high or out of balance with nitrate levels. Basically I'd hope lowering my phosphates a tad would get rid of the hair algae and bring some color back to my sps.
Or I could explore nitrate dosing to balance out the two, but I just don't know much about that type of thing.
