Ever since last Summer, I've been battling hair algae in my 120 gallon mixed tank. I didn't do much about it since we put out and won a bid on buying a new house, and we moved in Oct 2010. Since Oct, when I moved the tank, the HA has been getting worse, and Red Slime algae joined the party around January (when I switched salt, by coincidence?).
Light bulb changes, removing all sand, adding an additional macroalgae species in the 24" x 18" refugium, changing to "premium" salt recommended by a LFS employee (big mistake) all have not helped.
Nitrates are below 5, but Phos is .5 ppm, or ppt, whatever the standard measure is. I believe my rocks have become a phosphate sink.
So I just purchased 75 lbs of "reef saver" eco-rocks from BRS, and I'm about to soak them for 2 weeks in old water change water to get bacteria colonized. Then I'll remove all current rock and replace with the BRS rock. I plan on cooking the original stuff, my 5-year-old MMLR is home-made, I really like it, but I believe it's just filled with detritus and nutrients. my other rock is from our honeymoon in Aruba and is 11 years old. I love that rock, too.
Does anyone have any advise on prepping the Reef Saver rock from BRS?
