True. I do 50% water changes every couple of days for at 
least two weeks after putting the new background in the 
tank. The pH is usually off of the scale for at least a 
week. I calms down with constant flushing, although it will 
always buffer the water (as it continues to cure - maybe 
forever?) I _do_ use "acrylic fortifier" for the first (to 
bond to the Styrofoam) and last (color) coats.

This may not be the best for small planted tanks, as you 
will have a constant battle trying to keep the pH at 7 or 
below. I use it mainly for Rift Lake cichlid tanks (planted 
with Anubias and Vals, to keep this post on topic ;)

But, come to think of it, how many large public aquariums 
have I seen made of glass or acrylic? Hmmm...
