found this info on the web/
White algae is a fairly common form of fish tank algae. It isn’t dangerous for the fish but it can be a nuisance because it grows quickly and can envelop your fish tank. This type of algae is most often caused by having too much sunlight as well as improper nutrient levels.

See the issue is my nutrients aren't that high. And the tank has 4 80w t5s 15cm above on a timer for 12 hours a day 7 to 7 so cant be that

Also no sunlight reaches the tank it's in the middle of the room as a divider

if you have no corals try using less light during the day or nights I also use the same amount of light time on my tank for my Xenias but the algae grows like crazy . If you don't have a clean up crew may I suggest some hermit crabs and few snails . hermit crabs are so much fun to look at .
