I ran a CPR 102 on my 65 gal hex without an issue. If the power went out return pump stopped. When power came back on return pump and airlifter kick in and kept on working. I live in the country so power flicker often.
Best way to test for tempered glass is polarized glasses and a laptop. Laptop needs to be at a 45 degree angle to the glass. If all you see is a TOTALLY BLACK screen, not tempered. If there are white streaks in the black it's tempered.
