now that i have you tech guys here, do external recirc skimmers ever overflow and what do you do when they do?. i have used severa in sump skimmers and set them to run wet just to come home to a sump full of skimmage and a collection cup full of water. if they are external they could empty whole sump onto floor. couldn't they? the reason i ask is because i fear buying my new skimmer ive bought 3 and none good. now my short list is Er 135 rs, Das ex1 This is hwere the fear comes in and ati bm160. oh 90 gal barebottom heavily stocked a few corals but wont by more untill new skimmer.
