I am about to use my QT for the first time this weekend. I got a 10g Marineland. My tank will be gobys, dartfish and all around small creatures, so Im not too concerned with the size. More concerned with the filtration and temp, but I'm committed to a rigorous parameter testing and WC regiment.
However, if I had made it to this famous $1 per gallon Petco sale, I would have totally gone whole hog.
