I have a 20 long vert tank and am sick of misting it 4 times a day with a home depot squirt bottle. I want to buy the starter mist king system. Is it worth to buy the bigger pump? I want 3-4 nozzles in the tank. One in the center top, far left and right corners, and maybe one near the back aiming a bit forward/down. Is this too much for the pump to run? I've heard the pump the starter comes with is kinda weak, and it might be a good idea to get the stronger pump. Also, how do I drill the glass? In a 20 long, the glass is about 1/4 inch thick. I don't want to break the glass at all. Should I buy a diamond bit and lubricate the glass with cold water? I've never drilled glass before and if it breaks i'm f#*%ing screwed if it breaks. How big should the hole be? I've heard 5/16. Thanks!
