My paternal grandfather had multiple aquariums in every room in his house when I was growing up. He built his own tanks from galvanized angle-iron & glass that were sealed by tar. He built his own hanging filters, lighting systems, & had an attachment for his vacuum cleaner to clean gravel. I've kept tanks of my own off & on over the years, but this is the first time I'll be getting really serious about it. I'll be 58 in October and I'm disabled. Looking forward to sharing my love of fish with the community.
