Not that I'm smarter than the rest, but I appluade the people on the forum for posting mistakes along the way that I read before I made some of them. Having a buddy like Clay is a double edged sword. You love his enthusiasm to try, but watch and pitty those mistakes made in an upstairs home! I learned fast on the RO/DI thing. I did however try to RUSH things several times and made the damsel mistake, RBTA mistakes, aquascaping/frag crushing mistakes, over feeding by myself and house sitter mistakes, metal hose clamps externally and flooding floor mistakes, ATO not backed up-water level dropped below glass heater-blowing circuit breaker while gone and shutting all tanks off mistakes. i have learned to always have a fellow reefer available in case of Emergency while you are away.
