Hair algae problem help

[toxic111]

is this in the 120gal system? if so 10 gal should almost be your minimum water change.. I would recomend 10% water changes weekly. And up from there to battle the algae. It took me over a year to get mine under control. A sea hare or Turbo snails will help, but the orgin of the problem needs to be found as well.

Make sure to do a complete set of tests and post the results here. Also maybe ask the water store what thier TDS is in the water, or buy or borrow a TDS meter.
