90 Liter tank filled it put all the extras in ready and has a filter 24hrs later it has become a pale shade of green . theres not even any fish in it please help. !
 
Too much light. you need to do lots of water changes and cut back on the light. Or since you have no fish or plants just black out the tank for a week or so. cover it so no light gets in. That will kill the green algae. Then do a big 80% water change and add lots of plants. Fast growing plants like watersprite That way the plant uses up all the plant food before the algae can.

Rinse the filter in some clean aquarium water too.
 
It will probably clear up because anything that was stuck to anything you put in is now floating around so give it a day or two to clear up.
