I think its more than 1.1 ton, as 100gallon is 1 metric ton, and at over 200gallons your looking at a lot more wait than that.
The tank just blags my head, watching the vid my head is saying nice marine tank, and then another part of the brain is going "What the hell! thats a clown loach! wait they're not marine fish in there! cichlids?! eels, Polypterus Senegalus!!!"
it is impressive and it makes me want to upgrade to a 10' soon, too many people with 4-6'tanks now I need to go bigger hehehe!!
lol I know what you mean, even when I look at the video, it appears like a marine tank then you see something familar like a clown loach lol.
Also the weight could be a lot more, a friend said 1.1tonn but I cannot recall what he calculated or even if he was correct.
In regard a 10ft tank, good luck with that, damn , I thought this one was hard enough lol, I am guess at that size you could be looking
at having that built in situ if you are serious about it.
