Just noticed this article for a modular coral wall system. Was curious what other people thought of it and if it is worth it, or do people just use superglue etc? I like the idea of having GSP on the back wall on my overflow, however, I'm unsure how often I would need to trim it to prevent it from blocking the weir and nozzles.
