So quick update...

Just after I built my 300 gallon aquarium out of plywood (still haven't fiber-glassed it yet or order glass), I was offered a 300 gallon acrylic tank with an established setup (skimmer, pumps, reverse osmosis, chiller, lighting, etc.) and an assortment of 10 year old, beautiful coral for $1,500. Everything is in good condition. Tank is 8 years old, but no leaks or noticeable scratches.

I think it's a great deal, but I'm worried about transporting the tank (It's about 1.5 hours away) and not killing all the coral in the process. While I was able to successfully keep fish alive when I had a 75 gallon tank in college, it's been a few years.

Any tips for moving or ideas for the coral? Definitely need some advice. Maybe it's not worth it? Any horror stories taking over someone's existing system?

And just for sake of conversation, I was about to purchase all my fiberglass/epoxy last week. Below is my breakdown. If I still decided to do the plywood tank, do you think this would cut it...

1 Gallon Black Sweetwater Epoxy Paint for final coat: $78.00 (http://www.aquaticeco.com/subcategor...Paint-1-Gallon) — planned to apply 2 coats after after fiberglass & 3 coats of epoxy
2 Gallons 635 Thin Epoxy & 3:1 Hardener (EPOX-635315): $128.00 (http://www.uscomposites.com/epoxy.html#epoxhard) — should be enough for 3 coats
1 Pint of Black Pigment (AC-BL032): $12.25 (http://www.uscomposites.com/pigments.html)
4" 50 yard roll for corners of 8.7oz Fiberglass Cloth Tape (FG-C04R): $27.60 (http://www.uscomposites.com/cloth.html) — for corners
15 yards of 7.5 oz Fiberglass (FG-C0750): $94.40 (http://www.uscomposites.com/cloth.html) — for rest of the tank

THANKS everyone for your responses so far!!! Definitely helped!
