Wow! That's a really stunning tank. I wish they had bigger tanks like this. I also wish they had more low iron options.
The low iron 60P sized tank that I got is very high quality (the 720LI), and it was only $122 shipped. An ADA 60P is $197 shipped to me. Thus, a 60P is 61% more expensive than the nearly identical Mr Aqua delivered to my door.
I think if Mr Aqua offered more tank sizes with high clarity glass (and bigger tanks), and could continue to offer that big of a price gap, they would really dig deeper into ADA's market in the US.
