Yanbbrox;1897710; said:Cut out the light algae will die off, cover the tank for at least 48 hours and you should start to see improvements, direct sunlight is a no no if you want to avoid persistent algae blooms. If your going to add UV then make sure it is the last thing before the return as it could harm the good bacteria in your filter and you could end up with more problems.
Hope it works out for you
Thank you for all your help/
Have a great day
