I Have a 1 year old male ball. He is in great health and recently I decided to upgrade my tank. So I bought this monster tank 7' 2' 2' and I have to small heat lamps that dont seem to be doing the trick I have heat mats under the tank but I need to know how many watts my heat lamp should be. I am going shopping tomorrow and would like some ideas.. I would also prefer it to be red I like the look of the tank at night with the infared, thanks in advance
