arch
 

I want to make an arch between these two pillars I have in my 92. Any idea how I can get an arch across there without it falling over ? Nice and stable?
Some kind of glue maybe ?

thanks alot

If you have a drill, drill a hole into each piece and use a piece of plastic coat hanger like dowling

I am the worst aquascaper but you can also use zipties to secure it. I would get the black ones to use but whatever colour you decide on won't really matter as it will become covered with coralline algea anyway.
