I am upgrading from a 150 high to a 6 foot 220 gallon. I have kessil 350s on my 150 and bought one more to put all 3 on the 220. I also bought the hood for the top of the tank and I am not sure how to mount the lights. Obviously I am going to have to drill or cut into the hood, but before I start I would like to see if anyone has any suggestions on the best way to do it. The couple ideas I have; 1) Buy a long bolt and drill through the top of the hood and screw the bolt into the light. 2) Drill one inch holes into the hood and use the hook that comes with the pendants to hang the light through the hole. These two ideas I dont like because I have no access to the controls on the lights. 3) Use a jig saw to cut oval holes in the hood and mount the lights flush with the underside of the hood so I have access to the lighting controls. I am not crazy about this idea either because the fan on the back of the unit will have a small hole to blow through. Looking forward to any help anyone has to offer.
