My first tank ever was about 3 years ago. A 29 with 4 baby O's. Things have changed quite a bit since then. Still have the original tank & gravel though.
Ive had an AC operating for 12 years... Only thing I had to do was change the Oring for the Motor...Lou8337;2468227; said:I was 12 it was my first big purchase when I got my paper route. I'm 35 now. It was a 29 with what was called then a ac300 now called ac70. I got 2 O's one killed the other after a week and they were about 2-3". I still have the tank operating with the same hob. It has ran the whole time except for 2 of the yrs. I was in the Army. Never had to seal the tank yet either (knock on wood). Anyone else have an AC filter last that long? 21 operating yrs.
