Too Much?

I have no idea what you mean by "milli"?

Milli as in Acropora Millipora

I used a Coralife 150W MH with 2x65W actinics on it over a 20G with no sump for nearly a year without issue. As long as you slowly acclimate your livestock to that light level you should be fine. I never used a fan for cooling but it was near a window, so that probably helped.

BlazingArrow here on CanReef is now using this exact same equipment to keep basically the same you are wanting to keep. In there he has 2 candycanes, 2 hammers, a torch, a good number of SPS (which are doing well), an RBTA with two clowns, a wrasse, a goby and a shrimp... no sump. The only heat issue he ever had was when his stealth heater flipped out on him and dropped to cold then to super hot in a day. PM him for a discussion and some pics of his tank.

I have a 250 over my 20g side tank. nobody complained being in there.

The only concern I see is evaporation. My 20 was losing 2 liters a day with only a double PC light. Halides will definitely keep you topping up a lot. Adding a fan will help cool the tank but it also aids the evaporation process.


Go T5. Cooler. Less power to run them. Less evaporation.



Good luck.

I'd be looking at LED technology these days, especially for a Nano system.

Yup. Just downsizing back to a 20g. Its lit with a SWC Extreme Cree LED fixture.
Of course verdict is still out on its performance in my sps nano.

I used that exact fixture only 2" above my 10G nano, with a 14K phoenix bulb, and a modded AC110 fuge filter and everything was growing amazing. Check out by build thread http://www.canreef.com/vbulletin/showthread.php?t=71793

Aquaclear 30 HOB filter. I still use this on my 40G until I can get my sump set-up.
