And why?

Acrylic is lighter but can be twice as much as glass. Remember too, acrylic is very easy to scratch. But I think it would just be personal choice and what you can afford. A tank that big is not cheap.

If price is no object, acrylic all the way.

I would love to have had all my tanks acrylic...they are light weight, easy to move around and I think I remember reading somewhere that they hold in 8X the heat as glass.(don't quote me on it)... thats a huge plus with the temps we keep discus at.

Downsides, cost and scratches...scratches really not an issue in a bare tank.

Plus, acrylics don't rely on silicone for a seal.

I love acrylic for large tanks due to the weight.

I'll give you more info besides a one word post.......

Acrylic is 17 times stronger than glass, softer and more flexible than glass, making it highly impact resistant. It weighs 50% less than glass, making it much more portable and lighter. Acrylic insulates 20% better than glass, which reduces temperature fluctuations and saves on heating and chiller bills. Another advantage is that it has a transparency rating of 93%, which is as clear as optical glass. Only disadvantage I see is acrylic costs more.

you can get the used one too. I was luckly got hands on a lfs closing business but all come down to personal choice .

I prefer glass b/c of the scratching. There are times when I'm moving a tank 75G or larger that I wish I had acrylic though. It's a toss up between glass or acrylic with toddlers. Kids rub random things/toys into the tanks sometimes which won't scratch as easily but at the same time, acrylic may be more resistant to there more aggressive contact (banging---which is rare).

But yeah, cost is a huge factor for me too... especially for smaller tanks (55G or below) because I would rather have quantity for those.

If you go Acrylic - try this guy. https://www.facebook.com/AcrylicCreations Customer builder and has some good feedback.

When I talked with him about my tank he was on a 6 week backlog.

ohhh - and then, there is this CL post with both tank and sump... I would caution you on this one though as it is sitting in a warehouse. Looks great but who knows if it holds water at this point.

Hi Tankster,

I can't say for sure, but I think a lot of the Craigslist ads with personal email addresses, like the one you linked, are used for phishing.

Acrylic does scratch easy. But, can be buffed out. The weight difference is great when moving them. I've kept a look out for used ones. So far, I have some from 15 gallons all the way to 240.

I have glass and acrylic I love my acrylics I want to slowly replace all my tanks with acrylic, and they don't scratch that easy.

I would only use glass as acrylic is much harder to sterilise if you get an issue it leaches into the plastic. Glass can be treated easy.

I had experience with the 60 gallon glass tank before, it was leaking after 5 months I used it for my discus. it took me few days to clean the floor and setup a new tank from a leaking one. now I am using the 60 gallon acrylic tank for a year now, the tank is light and can be carried by myself. The glass tank is nice but you need 2 people to carry a 60 gallon glass tank. And don't forget to keep the receipt during warrantee time when you buy glass tank.
