Here is his reply to my question. Seems like a nice enough guy.

TamanduaGirl, that's exactly what I was getting ready to say ... probably no chlorine in the water there. And, actually, my friend has multiple 55 gallon tanks, and she has never de-chlorinated the water. Seriously. I freaked out one time when I was at her house and she was cleaning tanks. I'm screaming, "Karen! NO! Wait! You didn't dechlor yet!" She said she never does. Her fish are HUGE and very healthy.

I can certainly see goldfish being able to stand the cold water. I just can't see tropical making it. But who knows.


hello and good day
first of all i wan to calm you, i have the same 3 fish in the Taquarium and they are feeling great! (there was a forth fish that unfortunatly die a couple of weeks ago). when i designed the tanquarium my first concern was to the fish, the first mechanism was realy not suitable for fish, i dont know if you know it, but one can see how fish feel, when a fish is not feeling well it is acting wird... not swiming much, swim on the side, i dont realy know how to describe it but you can realy see when fish is not well. any way, when i tried the first Tanquarium i could see that it had bad effect on the fish after few minnets the fish were in it, when i saw it i took them out and put them in a regular aquarium, after tring it with many kinds of fish and discovring that it wasnt suitable for none of them, i transfered to plastic fish, by that time i had 6 big aquariums at home and some jars (big ones) with doesens of fish in them. Only after develoing the new Tanquarium mechanism i tried it again on living fish, this time it had no effect on the fish, not at all
the mechanism is build to reduce the presure when flushing, so the level of water goes down but the fish always have enoghe water to swim in and the are not vacumed to the drain hole. it been tested with many kinds of fish and the Tanquarium been found suitble for all the regular fish (zebra, siam, gold, koi, gupi ext.) but it never been tested on the more special kinds (like discuse for exp.) and i'm not sure they'll fit. my fish live in the Tanquarium for more than two year!!! that's mean it works, every one i asked who know something about growing fish told me it would never work... but no one told it to the fish yet, so they dont know it's not sepose to work
you can also add air pamp to the Tanquarium (not needed because of the flushing ,it's mostly for beauty,) and termostat but as i said, i dont think it's needed...
everyone are welcome to come and see it works
