one of my lighting systems just recently went down and coralife was nice enough to replace it eith a new system in the old lite i ran 250 watt 14000k lites when i took out the lamps i found one was cracked completley around the end so i had to go with the 10000k that the fixture came with till i get the 14000k replaced (warranty) now i seem to be getting some type of stringy webby brownish stuff, sort of like the mucus from the tube worms any ideas?
