my current tank has been running for just under a month now, and recently i've been noticing that on all the rubber bits in the tank eg suction scups, rubber seal on my heater are accumulating a translucent white gunge on them. does anyone know what this is / is it harmful? how can i get rid of it other than manually removing it?
i've wiped them all off several times and it keeps coming back
