Yeah constant levels of calcium are very important with healthy coraline growth, as well as intensity of light, not the photo period.
I would get some better lights on there. I have a 7g Fluval Edge Nano with a 150W Metal Halide and LED suppliments... and I have pure purple rocks, with coraline growing over coraline. I also dose calcium into my ATO resevoir. Do you have any corals in there yet? And have you done a water change since the setup?

I have always wondered how can people run metal halides over pico/small nanos. Do you use chiller to keep the water from boiling? Just curiosity

No chiller, and I have never had a heat issue or swing. Things that may contribute to this:
I have A/C in my house It has a 15g sump underneath Fluval Edge has almost a totally enclosed top The light is 6" above the tank All of those things put together make for a stable temp.

Still 150w sounds like a lot for like 20 gallon of water :| I use 62w T5HO lighting over my 20 gallon long and I feel like like it is responsible for the rapid evaporation.
BTW sorry for hijacking the thread :P Quote:

light over tank
 And you can see how purple the rock is...  Sorry to hijack the thread too! haha. But I have definitly found that keeping calcium up with strong light is the key to coraline growth.
