I had my new tanks made by Tony Perez at Sunrise Marine Tanks in Sarasota, 941-926-8265,
www.sunrisemarinetanks.com
I would highly recommend him. He was not the cheapest nor the most expensive. He was very infomative. I also think he is a third generation tank builder to.
I know others here have used him and been happy to.
Call me if you would like to.
He also built my custom water tank. Tony is the go to guy for tanks, in my opinion.
