Hi guys
I am need some advice on a new build.
I am planing to build a 180 gallon tank and i am not sure if i sould use acrylic
or glass.
Can you please give some advise.
Thanks.

My preference is definitely glass. But the choice is yours. Here's an unbiased comparison Glass vs. Acrylic - The First Tank Guide - The Differences Between and the Debate About Glass Aquariums and Acrylic Aquariums

Glass. You have to be to careful with Acrylic. And even being careful, you'll have to buff it out eventually. Its optically clear, and light, thats the only bonus. If your making your own, get a piece of Starfire Glass for your front piece, thats a much clearer glass than typical glass.

Thanks.
This is my first build and want to do it right.

I must preface this by saying I do freshwater, not marine:

After 6 years of having one glass tank and one acrylic tank holding the same basic kinds of fish, substrate and decor, glass has stood the test of time, and my acrylic tank looks like an ugly piece of crap that I haven't the space, equipment or knowledge to buff out. And I'm convinced algae roots better on its walls than the glass. I also blame my old pleco. I used to love that tank.

Acrylic is way easier to buff out than glass. But, thats the general idea as to why I prefer glass
But for your help.

Thanks Reefing. That's cool, but it would cost me more to buy the equipment and rent a garage than to just buy a new 29 gallon tank. You HAVE, however, prompted me to post my old tank on craigslist and let someone else deal with it.
