Aquaforest probiotic method

[intarsiabox]

Since I started using the Bio Pro S and NP Pro two weeks ago I have been getting a fluffy type of hair algae all over my tank. Nothing else is being added to the tank except Fozdown and weekly 15% water changes. Should I just stop using these products altogether or continue dosing to see if things get better over time? It's been pretty frustrating going from an algae free tank to having to brush off the rocks every two days.
