Yeah--my store is only ~400 sq ft so I prefer not to stock too much as it can be a tripping hazard
. I do try to keep quite a few Mr. Aqua tanks on hand though because they're very popular and my remaining stockpile of seiryu stone. I'm always happy to find ways to get whatever you guys need.
A quick word on ADA vs Mr. Aqua pricing--it looks like there is a bit of confusion.
I work with ADG, one of the NA distributors for ADA. The ADA 120P, which is the equivalent size of the Mr. Aqua 48"x18"x18" that you're referring to, has a minimum list price of $874.99. That's the minimum of what I'm allowed to sell it at (back in 2012). So you're looking at $599.99 vs $874.99 not $599.99 vs $699.99. However, I did a quick search and I saw that Adana (another NA distributor for ADA) sells it for $699.99 so maybe prices have come down this year, but you then have to factor in about $200-$250 for freight. To be honest, it's always awkwards working with distributors that sell direct. It really doesn't make sense for a retail store to compete with its own distributor. This is probably why a quite a few planted stores that carry ADA end up not carrying ADA anymore.
I looked into the Adana website more and though they have low prices, once you factor in shipping it's quite high. For example, the ADA 60P lists at $129.99 but then they charge $70 for shipping to MA. Don't be fooled! It's like ebay auctions that have a low buy it now but then they charge a ridiculous amount for "shipping and handling". ADG tries a different approach selling the 60P for $187.95 but saying "free shipping". This is all marketing.
So this brings us to another price comparison to consider.
Mr. Aqua 17.4G Low Iron @ $129.99
ADA 60P 17.4G Low Iron @ (approx with shipping) $187.95
Same dimensions, both low iron.
I strongly believe in providing options to everyone which is why I sell both Mr Aqua and ADA but I can confidently say that Mr. Aqua does not -demand- a premium for the brand.
Ultimately, I hope that you guys understand that I started my store as a consumer frustrated with local options and that my goal is to make things fair to consumers and disrupt the silliness that results from other stores doing what they do simply because they think they can do it. If you find a better price elsewhere I am always happy to price match, and if I can't I'm happy to explain why. When I price anything, I use the distributors list pricing as a guide, and then I look online for anything lower. I pride myself on being an open communication store and having "online pricing" available locally.
As always, happy to answer questions and clarify things.
NOTE: One interesting thing to point out is that ADA low iron glass appears light blue at the edge, whereas Mr. Aqua appears more white.
