Fish tank water pure green?
Had 250l tank for 4 weeks, just added some fish. done numerous small water changes and the water has always been crystal.
Just recently the water has been turning rapidly green. i did a 50% water change and that has made it a million times worse, I cannot even see into the tank now. anyone know what this is and how to fix it?

You need to clean the whole tank, not just the tank itself but anything that's in it too. A full water change too.
