i just did the silicone and plexiglass panels in a 10g. i will tryo to take a picture and post it for you. i think glass would be better than the plexi. it will eventually become brittle, but i had the plexi and i will have a bigger tank before this happens 8)
i also put a chamber for the input to flood into over rock rubble and a bubble trap with two extra baffels.
as long as you mentioned it, whats the deal with mangroves? i am seeing them come up alot recently
