My 29g reef is in a glass tank that is over 5 years old, and has a ton of scratches. I bought a new one with black silicone seams and waited until I had time to transfer everything into it. Here's the old tank:
While studying the 55g closely, I found new growth of the blue Milleopora on the LR it had been touching until recently. I think the sand shifted and caused the rockwork to move somewhat, and the colony no longer is in contact with that spot, but it looks like I may get a separate colony one day. As of now, it is about the size of a dime or less, but the color and the hair-like polyps are unmistakeable.
Word to the wise: Be very careful with kalkwasser in your main tank. I mixed up a paste of pickling lime to kill one large aiptasia. I drew this mixture up into a syringe, pulled the rock out of the tank and proceeded to inject the vile beast until it resembled black tar. Then I rinsed the spot with another syringe of water.
Chemi Clean works! I've always avoided using chemicals to remove problems, but the cyano bacteria simply would not go away entirely. I'd lost a couple of frags to this algae, and done all the normal things to avoid fueling it any more. I cleaned the skimmer regularly, used a turkey baster to blow off the stuff anywhere I saw it, and even siphoned out what I could see on the DSB and rockwork.
A very sad occurance.... I had a beautiful baby gold Maxima clam shipped to me from a friend in another state, which I carefully acclimated to my tank for a couple of hours. I placed this 1.5" clam on an empty shell in the center of the rockwork in my 55g under MH lighting.
