I have an anubias with the same problem. Removing leaves on one of those is much more drastic than with the swordplant! So I have just been trying to keep it shaded and basically, doing nothing and wishing it would go away! I don't see it anywhere else in the tank.
I have vals in there and have heard excell kills them. The anubias would be easier to move, so my question for Zig would be do you think it would work for me to set up a small extra tank to dose the anubias with the excell? Or would it just get "reinfected" upon returning it to the main tank?
Tammyliz......Anubias just seem to be prone to algae, if it was just one plant i would use a spot treatment with the excel, basically you get a syringe and fill it with some excel, use about 5ml for a 10gallon, switch off your filter and make sure the water is still, and then you inject the excel from the syringe at the infected areas of the plant under the water, its a localised treatment rather than treating the whole tank, within a couple of days you should see the bba change colour and then you know it is working.
Follow the instructions on the label, you might not have to overdose if you do it this way, excel will definatly affect certain plants and probably kill them, vallis and egeria are the main ones that people seem to have the most trouble with but it can affect other plants as well, you can never be sure until you dose your tank, some people have no trouble at all and with others it just melts certain plants really quickly, within a few days.
The plant shouldn't get reinfected if there is not bba in the other tank, if there is, treat the whole tank.
The thing is with bba that i find, is that if you dont treat it or get rid of it, it will spread throughout the entire tank and is really stubborn and difficult to remove entirely, ODing the excel is a good effective method of dealing with it, just watch your plants and fish when you do it though, i had no problems with my fish but it did melt some of my plants, but it got rid of the bba.
