hi viktor. Ive put a fair bit aside for the tank, i just want to make sure i get the right one. I was wondering, as you clearly have a lot of experience with ADA tanks ( just looked at your showroom... jawdropping!) is there a huge difference between ADA glass clarity and silicone quality compared to low iron alternatives? I kno ada do a 180-p, but i dont think you can get hold of it in europe 🙁.
There was a thread before on ADA glasses a few month ago. Did not find it. Anyway to give you an answer it will be a little longer
🙂
Short story is. Yes ADA tanks are great, better than any custom built i've ever seen.
Long story......
OptiWhite as it was said before is a glass brand of Pilkington. This was the first glass which used in Europe for low-e tanks mainly by ADA.
Since ADA manufactured all of their aquariums in Germany in the past. And Pilkington's Opti was manufactured in G as well as i know.
There were clear glass on other side of the world like Starphire in the US etc. So this is the EU market only.
Since this was the first clear glass in europe what used for aquarium build, people started to learn the brand and for today all aquariums are optiwhite which is lowe. But that is not true.
There are at least 3-4 other glasses in the EU from the largest glass manufacturer who produce lowe glasses. The clarity is similar, but the overall appearance could be better with other glass.
OptiWhite glass has greenish hue on the edges. Others has light blue and now the latest what i've seen was kind of a light grey. When you see these glasses next to each other you prefer the light edge ones. Colorless.
So Clearglass from Guardian is a nicer one in appearance.
Than there's the gluing. I would say this part is improved a lot in the past years, but sure there's a difference in a premium tank and a custom one. The nicest tanks has a perfect almost non visible and everywhere even gluing. It is up to you how much it worth for you.
ADA moved the manufacturing from Germany to China 2-3 years ago to cut cost on logistic. By moving the production they also found a partner who produce higher quality tanks than the earlier provider.
They added in extra thickness for safety, changed the glass to a clearer one and nicer edge one, and improved the gluing. So you can see in their ADs that the new glass is nicer etc etc, that means compare to the old one which produced in Europe this is a much nicer aquarium and this is true. ADA has one of the best QC in place and they are selling a lot of stuff. TMC glasses and NA tanks (NA seems to be in a premium league so higher level than TMC) are good ones, but sometimes when you're on a higher level, you have more possibilities to use more machinery, money etc to give better result.
So without sounding an ADA rep here these tanks are superb, but only for logistic reason ordering a giant tank like this from Japan is not so efficient.
it is up to you to go the custom build way or select a brand who you feels ok with like NA or others. If you go on the custom way make sure the builder has a lot of reference in transparent rimless gluing on larger tanks too.
