I uncovered the tank today and a lot of the algae was gone. I did a big water change and added flourish, excel and nitrogen. All of the fish are fine and hopefully the rest of the algae will die off. Thanks for your help everyone.
I think excel would work, it is essentially a biocide with the added benefit of adding carbon. I would definitely start using it but I don’t recommend you over dose it. I have seen it burn my java fern.
If you are going to go the flourish route don’t forget the Iron.
Nice to see things headed in the right direction.
