I was having troubles reading the label on the ballast which i mounted on the back of the tank. That is until I remembered I can swivel my disco ball to hang over the back of the tank!
Turns out this is an m81 ballast (hqi) so I'm going to try out the radium 20k (which runs best on hqi) which I read is very intense with not a ton of blue but nice coloration of the tank.
