Since upgrading my lights algae has become an issue...my refugium can no longer keep up so I have begin today to use Rowaphos. Time will tell.

I put some dried live rock that was given to me into my 50 gal when I started it. When I bought my po4 testkit 3 weeks later I was at 5ppm. I started doing 20 percent wc twice a week and quickly got it down to .9 ppm. Gfo diddnt do much for me. Algea scrubber built from anaquaclear 500 helped alot.foz down brought it down very fast. Tank looked like a snow globe. That was about six weeks ago. Now phosphate leaches from the rocks at about .1ppm every couple of days. Foz down will drop it to zero in an hour. Hair algea is dying and phosphate is leaching less and less.
