I have found that a good UV helps alot (although half the people on here will say it is useless).
Yeah had that argument on here already, lol. All academic study suggest it does AMAZING things for aquarium health when done right and still has benefits when not optimally setup. I have designs for a QT setup that I'll get up and running in a couple months that will be centered around UV filtration.
Thanks for laying out the treatment for me. I'm pretty scatter brained ATM, been obsessing over this ever more each day since the last fish bought the farm. I will do as you say!
