Help with sps!

[tang daddy]

The valonia algae can be taken care of from emerald crabs as I had the same issues as you about a few years ago, the cyano is abit of a battle, do more waterchanges and try to reduce feeding, you can also add bright wells (slowly) mb7 to help start another bacteria culture to out compete the cyano. I tried numerous approaches to rid cyano from sugar dosing which is a carbon source to manual removal. I finally caved and used medicine the cyano disappeared but the clams didn't like it and in turn lost all the clams as a result the tank turned into clam chowder and I lost 90% of my sps. $6000 in livestock down the drain.

Not trying to scare you but from experience will never use any Meds on my tank ever again. Try the filter sock and turkey baster technique to alleviate cyano or even adding mb7 which should out compete the bacteria.

Good luck!
