Miracles makes some of the best tanks around. they are made here in the greater toronto area. some of mine were almost 20 years old before I sold them. never leaked, never been resealed.
you pay more for them, but you pay for the quality.
and as an added bonus, all thier tanks come with black silicone unless otherwise ordered.
which is a bonus. my last tank was an Aqueon tank (only because Miracles did not carry a stock 72x18x29 tank) and I had to pay extra for black silicone..with miracles, its made that way, so no extra charge, which is great.
