Leave the glass in em
745 cfm is more than enough to cool a pr. of 1000s .
I cool 3 -1000w inline w/ only 630 cfm .
Run em as close as you can get them w/o causing heat probs, or bleaching either one . I use a laser thermometer and shoot leaf surface temps trying to keep them below 78 degrees . Cheap useful tool for $20.00 Google em .
