I have what I think is beard algae on some of plants, the treatment seems to remove them and place them in a solution of 10% bleech for 10 minutes, does that sound right?
You can do that but I really wouldn't, it could make things worse for a few reasons:
Removing the plant from the aquarium disrupts the root system putting the plant under further stress and hinder future growth, this can encourage more algae.
The bleach its self will stress the plant, a stressed plant will likely encourage more algae
It doesn't address the route cause of the algae and thus it is highly likely to return, often with vengeance due to the above
You can spot treat effected areas with a glutaraldehyde based product such as Seachem Excel or Easy carbo. These are marketed as liquid CO2 and increase the available carbon in the tank but they have a side effect of killing algae if you spot dose with a syringe/pipette. The downside is that these products are toxic to livestock and plants if you put too much in and it still doesn't really address the root cause, I wouldn't bother unless its getting really bad.
You are better off removing the effected leaves and addressing the route cause.
Algae grows on plants because there is something that is stopping the plant thriving which means there is an imbalance somewhere in your tank its either:
Too little nutrients
Too much organic waste
Low or fluctuating levels of CO2 in the water
Lights on too long for available nutrients or CO2
Lights are too intense for the available nutrients or CO2
It really is trial and error getting the balance right, unless you have a CO2 system then CO2 is fixed which means the only things you can control are lights, nutrients and waste. Frequent large (50%) water changes are the best thing you can do to combat an algae outbreak while dialing in your lights and nutrients.
