i just started cycling my 46 gallon reef setup. i have a protein skimmer, should i run that while im cycling the tank? Should i run the lights? Also, i notice the water has alot of very small "fibers" for lack of a better word floating around..not sure what it is, anyway the water isnt cystal clear like i think it should be, should it be? Ive only been cycling for 4 days now.
