I guess I have

I had 8 fans in that hood. Pat used to Joke and ask me if I needed flight clearance for it. On that tank I had 2-250 and 2-400's and it was 120 gallons. On my 270 I have 2-400's and 2-250's lying in wait until I can get them over it.

I think I have tried just about every form of lighting available (maybe next tank I will use some solar tubes as well) and keep ending up with MH as my light of choice.

The 270 is actually turning out to be an amphopod factory which will be nice when I add a pair of mandarins way down the road.
