Thanks for your reply creighton. How do you recommend I dose excel? I've read that some spot-dose it using a syringe. Do I do that, or do I dose the entire tank based on label indications?

Yes, I'll defiintely try to up the circulation in my tank and see if this helps.

But there's one thing I don't understand. Excel's a carbon supplement. I've injected enough CO2 for almost all plants in the tank to pearl. So how will excel help rid of the algae?
