Title: Green algae
Post by: Mike62 on February 25, 2011, 09:35:52 AM
I have noticed on one of my live rocks, a hair like green algae growing. I took the rock out and scrubbed it clean, and put it back in again, several days later, the growth is back. The snails and crabs I purchased dont seem much interested in chowing down on it, and the lazy tuxedo pincushion sea urchin that I have doesnt ever seem to venture onto that rock. What is there out there in the world that I can get that would make a meal out of this stuff?
Just for compatabilities sake, I have two clowns, a desjardini sailfin tang, a blue hippo tang, one damsel and one black cap basselett. (plus a pair of shrimps)

Out of curiosity... how big is the tank?  How much Rock?  What are your water parameters?  Light Schedule? 

My Yellow tang I had would devour hair algae.  You can also get Mexican Turbo Snails.  They seemed to do a great job for me as well.

I am a rookie to saltwater, so take my thoughts here for a grain of... uh... salt. Just sharing a speculation.  

I picked up a few balloon mollies for my saltwater.  I read that they eat hair algae.  My own observations is that they do indeed snack on the stuff, particularly if hungry (mine always are, even when well fed).  Perhaps you could pick up one or two of any kind of molly that you find attractive.  They are pretty cheap (what else is cheaper in saltwater fish???), and if they do the trick then great, but if they don't, well, it's not a big loss either.

From my own research, and now from my experience, acclimatising them to saltwater is incredibly easy.  They handle the transition probably best of any other fish that can be acclimated from fresh to marine.  Simply place them in a bucket with the water they came with (a few cups worth), then simply take a cup of water from your tank every 15 mins or so and dump it into the container.  No "slow drips" or complicated shaman dances required.  Two to three hours later they may be let loose in your tank.  I've already done this with several fish, and it works.  I was surprised how well they adjusted so quickly.

55 gallon corner tank. Approximately 75 pounds of live rock, only one rock appears to be infested. Water parameters are good, phosphate is 0, nitrate could be better but its within acceptable levels, the blue lights are on from 11AM to 9PM, the white lights are on from 1PM to 8PM.

How old are your lights?

Do you use RO water?

What test kit are you using for PO4?
