This weekend I scraped the idea of staying on the lighter side of the amount of live rock kept in the tank. I have been battling GHA a little so I went back to my roots of what I have had success with in the past. I added about 35 pounds of more live rock to the DT and plan on adding more to the sump area or looking at the idea of the ceramic biological blocks in the sump area. I also started dosing vinegar on Saturday. After adding the live rock and dosing vinegar the GHA is pretty much gone. Diatoms are still covering parts of the sand bed, but most of the diatoms on the rock are gone because of the cuc. Waiting for the sand sifting cucumber to start getting busy. I have not seen it since it was added. I know it can take awhile for them to come out. The Royal Gama was also moved over from the QT tank. It is eating and comes out for short periods of time, but finds comfort in the rock work for now. Will try to add photos this week.
