Holly crap! I don't feel like I'm helping this little one as much as I should be. Did a 50% water change a few days ago. I've had a mess of problems with a few other tanks that I've been focused on more. But, I did a ammonia test today. Came out to be a little over .50 and under 1. So about .75 not good! I freaked out. Did 6-50% water changes. Cleaned out in intake tube and dunked the cartridge. Wiped the tank down, vacuumed, wiped heater. Goodness! Dosed with stress coat only on last water change. With a few extra drops. I noticed not eating much lately. Now I see why. Gonna throw some dried blood worms, maybe we can get back on track. Still looks good thought.
