Working on colouration and growth - update.
The downsize to the 40 gallon has been a good move for the most part, but I have faced a couple challenges in the process. I kept all of my fish from the 75 gallon (not a mistake in itself) but as I dont test for nitrates they were slowly rising, they read 12ppm when I check a few weeks ago. So I pulled the 3 fish out of the tank and gave them a better home in a 65 gallon. Unfortunately, I had an alk swing in january and bleached/burnt a couple of my acros. As they were recovering I started noticing the underside of a few of my acros looked like it was being eaten away. After some research I found that Ostreobium (green coral boring algae) loves high nitrates and was likely the cause. It's done some damage to the underside of my acros, but they continue to grow and colour up. Im hoping the reduction in nitrates and some super glue over the affected areas will stop it.
My chalices took the worst hit in the alk swing, but are coming back nicely. The mummy eye chalice below is on my frag rack now and is deeper and bright in colour than ever. Im slowly dialling the radions up, trying to improve growth, and seeing some great improvements in colouration on my acros too. Growth has improved but I think this is more because of my alk stability and low P04. I've noticed that slow increases in my white LED's has the best effect on colouration in both my LPS and SPS.
Just added this milli yesterday.
A red plant from Albert, encrusting like a beast.
I love the little flower polyps on this acro.
Reeftech Starburst (also from Albert) has gone red in my system.
Meteor shower cyphastrea growing nicely.
Mummy eye chalice recovering from alk swing and heavy fragging. Thought id lost it.
My fav purple hammer. Got it as a sad little frag, now it's grown into 2 beautiful colonies.
