I was able to buy a JBJ 12g nanocube for $30 for my QT tank. (I know I sound like a broken record, but gotta love the local reef club!) When I added more LR to my main display, I took what I'd guess is 10-12 lbs of LR and added it the nanocube with 50% water from the display and 50% newly made RO/DI SW. Since I put cured rock in, I'm assuming there won't be much of cycle, but will keeping this running be sufficient? here is the summary of the tank right now:
12g JBJ nano (stock PC lighting, stock pump)
10-12 lbs LR
100 micron filter sheet (inserted when needed)
bare bottom
I plan on doing frequent water changes when it has fish, so I don't have to buy a skimmer.
Anything else I need to make it a good QT? I have a seio 820 I could throw in but I'm worried this would be too much flow for this size.
Also, I'm wondering when I should start using it. Right now I have one fish in my display - a
royal gramma that has proven over the years to be indestructible (previous owner thought he was lost when upgrading tanks, turns out he lived for a few weeks in a trash can of saltwater in their garage, and he was the only fish to survive my heater malfunction leading to 93 degree temp). Is there any reason really to QT the next fish I add? I'm thinking they will go straight to the display, then I'll do QT with subsequent fish.
