acrylic baffles thickness in acrylic sump?

[Wall Street Reef]

Hi all! Going to get some acrylic cut today and was wondering if 1/8 would be ok for the baffles. sump would be 21x14 and would hold roughly 5 gallons with live rock and everything in there. the reason im wondering if 1/8 in would be ok is because they only have red in 1/8 and I wanted to use red for one the walls. any thoughts on this would be greatly appreciated, thanks!

Sorry if this is late, but 1/8" should work on that volume of water. If you can, caulk both sides for a good seal.

well I ended up go with 1/4 all around and found out after that 3/16 would have been half the price which was a bummer because had already placed the order. IN the long run though I think itll be safer to have the quarter in thick for the entire sump. thanks for the reply tho.
