I use my potting shed for brewing which contains a fair bit of glass, after mashing i racked the wort off into a bin and fermented the contents [5 gallon ] the only mistake i think i made was while it was fermenting i put the lid on the bins

After it had finished fermenting i racked it off into a king keg added a bit more sugar and finnings so it would pressurise the king keg, my problem is i cant get neither of them to clear i was advised by my loclal brew shop to rack both of them off again which i have done , it did a make a small differance but not much.
They both taste ok, but dont look very presentable, i wondering if it could be with me using the potting shed to brew in, when the sun rises in the morning until about 12pm it shines through the potting shed onto the king kegs i stand the king kegs on some benches.
Anybody got any ideas i would br grateful if you have. cheers
