Eep! 88 to 76 is a huge swing! Try keeping your base temp a bit higher like 78 or 80 degrees, and then use fans to keep it down. You can also time your lighting so it's on during a cooler part of the day. Luckily I have central air, and the tank doesnt' go above 80 even with the halides and T5HOs running.
