check with tropic isle maybe they can or know somone who does.
the aquarium gallery in nh had somone come and look at there big tank but it was big BIG bucks to fix that one.
Ian Caperton can probably do it. But how to get a hold of him! You might try posting on the Boston Aquarium forum. He came to the last meeting where I spoke.
I bet "Aquarium Nut" (Steve F) over in the Skiptons forum knows how to contact Ian. You should PM Aquarium Nut and request Ian's phone number. From what I remember, Ian doesn't do email.
Alberto why not fix it yourself. get a good few beefy guys around and cut off the panel which is leaking and reseal If you need some help drop me a pm. Thanks
