Thanks! I will keep up with the Excel for a few weeks and see how it goes. I'll post some new pics in a week or 2. This may be my last attempt with ridding the Parva of algae before I get rid of some of it and try another foreground plant. I've like Staurogyne a lot, but not sure about the size of it for a small tank.
I am not sure what the correct 'dose' is for peroxide/gallon.. But I just turn the filter off, put some peroxide in a syringe, and shoot it at the areas with algae. I let is sit for about 30 minutes, do a small w/c and turn the filter back on.
Don't give up on parva there is reall no comparison to a nice healthy parva foreground.
