I found these mysterious white salt particles covering everything in my sump... They are on the aquarium sump doors too, but I think thats because when I clean the aquarium a few drops roll down it that I didnt notice. Inside the sump is a mystery however. I read about salt creep, could that be it? The aquariums almost a year old. The weird thing is that it appeared all of a sudden... One day it was fine (I checked the sump to add water to my ATO) then the next it was covered in salt particles, and to add to that my heater was opened up and the wires were all over the place. I dont know what could have happened, any idea about the salt particles?
