very interesting thread, I always thought flywood tank build with fiberglass until I came across this. So you mind I ask a few question for my future tank as well. How is this rubber works with algea? can we clean it just like we clean the glass? and how is seal with the bulk head? about color, is there different color for this rubber? btw I am from BC and there is no liquidrubber store here so can I order it online or you know the website I can order it from?
