Tank size decision

[DTz]

Hey guys. I’m currently running a 6x2.5x2.5 feet sps dominated tank. Few days ago my wife decided it was a good idea to help clean my light covers with soap and the soap fell in to the tank and killed all my fishes + half my sps corals.

Rather than restock, I’ve decided to take the opportunity to upgrade to a bigger tank.

I’m deciding between upgrading to a 8x3x2.5 and 9x2.5x2.5. The 3 feet width will have a higher water volume. But was told 9 feet will require less thick glass. 12 mm glass for 9 feet and 15 mm glass for 8 feet.

Question is, which one will visually looks better? Need some help on deciding and pls offer as much reason behind. Thx

@Joe Glass Cages can give some insight on the glass and difference in viewing. My only thought would be to make sure that extra half foot of reach isn't going to be too much of a pain for you.

9 foot for me…you are unlikely to see the benefit of having a wider width but will notice the extra length, plus the thinner glass.

Nice problem to have!
