I'm out of outlets to plug it in ....... and I already have power strips going in. Because the tank is an odd size (5ft long), I have 3 t5 light strips, one 48inch towards the back, then 2 24 inch towards the front but centered on the sides (the middle doesn't get as much light). So, my lights take up 3 outlets by themselves. The 2 filters, 2 heaters, powerhead, air pump, moonlights, .......etc.... I think I have more plugged in for the fish then for my computer.
I do however take a flashlight on one side, but that's more of a beam light.
I only mentioned the "getting under there" part of cannisters, because I have hip problems and sometimes that movement of bending, crawling and wiggling something heavy at the end of my arms is just impossible and I either have to get help or wait until my hips go back insync to do it myself. But, they are really nice filters.
Grump-- You won't need anything to dampen sounds, once it's going and all the air is out (this takes awhile on first use) you can't hear it run, it's quieter then the hum of florecent lights in a workplace (fluval 405 anyway) I think you'll be happy with it (after all you're a marine, you can handle dark,tight, crawling around while dragging wet stuff)
