Simply Koi and More Koi

Hi,

I had to do the 'brick acid' trick for the oldest of my Nexus 200 to clear the limescale build up as well. This was following advice from EA when I called them as I was suffering from the same prblems as you appear to be,

Are the bubbles produced by protein unstable when subjected to UV/sunlight as over night my prteing skimmer produces lots more froth than during the day?
