Coralline Algae

[sao72358]

I have approx 40 lbs of rock in my tank. My problem is that it became so inundated with bad algae that the only way to get rid of it was to remove the rock and let it sit out in the sun for about a week. Is it true that my rock can now be considered "dead"? Is it possible to grow Coralline Algae on this rock or do I need to discard it and start from scratch?

what are you calling bad algae?? is it the green hair type? if so an algae blenny will clear that up for you in no time.. if its slime algae then the problems in your water
good luck.. fix your problem dont start over

I use RO water from a good quality salt water fish store. What water quality issues would cause slime algae?

I would say your live rock is dead rock now, but just get some more live roci to seed your dead rock. You don't have to get rid of your dead rock all together

Concur with Vibez on the live rock. It needs to be reseeded with bacteria. There are hermit crabs would have taken care of the hair algae. Slime most likely from nitrates (excess nutrients in the water).

Just remember that your "dead rock" will have a huge die off and if put into your tank will start anotehr cycle. Not sure how big your aquarium is, but your "dead rock" will actually make a great base rock when you purchase new. You dont need alot of new live rock to seed your other rock either, I would imagine that 10lbs - maybe even less, would get things going for you again. Just make sure that other rock has re-- cycled!
Edit: Also, check your phosphates..this is one bog reason for red slime algae, cynobacteria

I used dead live rock that sat in a storage unit dry for nearly two years as my base rock, and then seeded it with a few nice pieces of live rock from the lfs. My tank has stabilized, and it appears that a few spots of coralline are appearing on the old rock.
