Contamination Via Used Equipment

Alan....

When I brought back my 6" clam and other corals and rock from Calgary, the person that owned it before had a ton of hair algae all over her rock and corals and I wasn't sure if some of the corals were going to make it because it was overridden with hair algae...she had a little bit of desireable algae (bristle)... But I put it in my tank anyway and my lightiing isn't the greatest...I think it's like 4000k 400 watt metal halide with actinics, but I used a gel to boost the colour temperature. I was worried that the hair algae would grow like crazy. I physically ripped out as much as I could but it was impossible. But within a week, all the hair algae was gone (from my tang and clean up crew - snails and crabs)...they all jumped on the new rock right away and took care of it. So I wouldn't worry about a bit of hair algae on the PH. Hope this input helps..
