Can you please help with some advice. I have been cycling my 125ltr tank for 5 weeks now and everything was going well until a couple of days ago. I have been completing 10% water changed every two days and testing nitrates and the levels were always reasonable. Now however the levels are now really high and I think I may have lost a fish (I was cycling with 6 danios). All the other fish look very healthy and are feeding & swimming well. Tonight I have changed 25% of my water.
At the same time the nitrates rose there is a brown algae forming on my gravel and ornaments. I have my tank light on for 8 hours a day but there is natural light during the day.
Any advice would be much appreciated.
