I had been fighting a cryno algee problem in my tank about 6 months ago. I had let my cleanning crew dwindle down, this may have caused the problem, don't know what really causes this problem in a tank. Anyway, I increased my clean up crew, I added a MP40 to the tank to increase flow, between water changes
I put a filter sock on the tank, put a pump into the tank with a hose on it and shot water over and around all the LR trying to remove the detrius out of the tank, made sure I kept the detrius out of the sump. After all of this, I started winning the cryno battle, I have a feeling though, that if I let up at all the problem will be back, I don't see any in the tank at this time though. My point to all of this: I have about 130 pounds of live rock in the tank and another 25 pounds or so in my shed that I have taken out of the tank over time. I was planning on buying new dry rock for the new tank and seed the rock with some clean live rock. If I could some how make sure there isn't any cryno on the live rock that I have in the tank, I could use that in the new tank and save myself around $300 to $400 What do ya'll think?

To be honest, I don't think there's any way to completely remove the possibility of cyano, whether you use new rock or older rock. Possible culprits for an outbreak are high phosphates, high nitrates or lack of flow.

I've used Red Slime Remover successfully, but you should only use it on a mature tank that's more than a year old. In younger tanks, it can cause major problems. If you want to use the rock in a new tank, it's probably better to treat the rock now.

I don't see any problem in using the dry rock you have, as long as it hasn't been in contact with chemicals in the shed.
