As to the OP, my vote is for the glass. Even though I have a 100gal acrylic, I'm planning on mostly glass for my fish shed. I don't like the way the front of a large acrylic tank bulges, and scratches, and can't be scraped with a razor.
Again thank you everyone for your thoughts. Although it may seem on occasion that I had already made up my mind when asking such a question, I can assure you that your comments really help support the conviction either way. In this case you have defiantly help me feel much better about perusing glass as an dependable, durable, and recyclable standard, even if it means I will have to settle for a sized under 225 unless I site build my own.
True! Steel wool also (don't look at me all crazy - it works!)
I have both glass and acrylic. I agree with the cons outweighing the pros on acrylic - that being said if there is little chance of your tanks inside being scratched or if there is a chance your aquarium may take a bump or two (high traffic area) the insurance of having acrylic is nice. All my small tanks are glass and my only (for the moment) large tank is acrylic - If I ever I get my big tank (350ish is big to me) It will probably be built in so it will be more thank likely plywood with a glass front (throwing another option into the mix) any thing bigger that I ever own will be probably by outdoors in the form of a pond
And I get the part about 99% usage and 1% transport. My mom & pop LFS really tried to talk me out of acrylic and when I asked why they use it almost exclusively, they said for ease of cut pluming the sides of 50 tanks into one large jacuzzi pump filter and manifold. But at home they only have glass.
very cool but it raises the question - why is there not (or is there?) an acrylic tank with an anti-scratch coating (one that actually works) on the inside and outside of the tank? If this is out there I would love to know. The coating would obviously need to be transparent and tough enough not to scratch as well as stand up to frequent cleaning (be able to take at least a 3M scuff pad)
I dont know if this has been mentioned before yet, but glass is nice if the tank is setup around children and pets. I've seen nice acrylic tanks ruined by little hands with toys or finding the mag-float unattended.
I have heard the same thing from my mom & pop LFS who have almost all acrylic as store displays. That acrylic is great for multiple displays to sell fish as people could care lass and never notice the scratches. But for home display it is not good especially if you have big pets like dogs or kids with sharp toys like a good friend with a 5 year old and a fork. However if your a retailer or biologist with many tanks, glass is not an option and acrylic is the only way to go.
