Excel and val. Contortionist?

[FWFishTanks]

My tank has acquired some BBA, and I plan to do less feeding to encourage my SAE to eat the algae and reduce waste. I am also having my light on in 2 hour periods of on and off, to help prevent algae development. I also plan on dosing excel, but I have some contortionist Val's and do not want to melt them. Could I dose a ten gallon dose (75 gallon tank), instead of the full dosage? Would this still melt the Val's?

I think plants need 4 hours of light at once to photosynthesize ?

BBA you can try squirting excel or peroxide directly on it. (?)

1/2 dose of Excel may be ok ?

I have Vals, but they've been habituated to excel from my friends tank. I don't dose daily.

Dosing at about 1/7 strength may or may not cure BBA but it's worth a try. I had BBA and successfully cleared all of it with normal dosage of Excel but all my Vals melted. I planted crypts, Java Fern and Moss which have flourished. I use Excel daily and inject Co2 and use Flourish. My lights are on 12 hours a day, although they are only the normal T8's and not overly bright. My red crypts are about 18" high and sending out runners. All in all I don't miss the Vals.

I'll give it a try, and I'll see what the 2 hours periods do to the plants. Thanks for helping!
