Hi everyone,
I'm preparing a tank move, but LFS is also having a MAJOR sale coming up so I'm trying to get some QTs set up so I could buy fish and coral to stock my tank. If I could come up with a decent enough stocking list before then at least. I have 3, 10 gallon tanks. I plan to keep one as the coral/invert QT, I do plan on doing a proper QT on all corals and inverts I've read too many scary threads to consider otherwise.

The coral/invert will be a 10 gallon. I have a light from amazon I know it's not really going to lead to much growth but it should keep it alive for the 76 days. I plan on putting my inverts in this same tank until they molt/76 days (maybe less depends on how dangerous I'm feeling). Now would a HOB filter be enough flow if I were to keep corals in there? I tend to keep my water levels below the top which means the water falling out really moves things around but would something that needs more flow be alright in there like a SPS? I could also throw on a little power head, but I don't know how much flow would be too much flow especially if there's a mixed group in there or with shrimp. What would too much flow be or a good flow?

Next my fish QT. Now I've been researching QT methods and I think that I'm going to be doing the TTM with BiFuran on the appropriate days. (LFS recommended it, I also know they run a low dose of copper in their systems). My DT is going to be 75 gallons, I want to make sure my QT is going to be big enough for any fish that I might get so I'm guessing a 10 gallon isn't enough? Since I'm using TTM would I be able to use storage totes. In particular I'm going to eventually want a tang, so I feel like 10 gallons would be too small even though I'd be getting a very small one. What's the best/cheapest option once again with a HOB or powerhead.

Coral QT - I would put a small powerhead in there as well to give good flow throughout the tank. I currently use a 20g long for my coral/invert QT... replacing it with a 29g taller tank very soon. This will allow me more depth, etc... to put corals for different light requirements.

Fish QT - i think it would be difficult to do TTM with anything bigger than a 10g tank. When you get to your tang, buy it really small and the 10g should be fine. Or, get a 20g long for a little more space.

Difficult and expensive! I've considered a 20 long, but then also considered the fact that I'd need 2 if I were to do TTM I feel like going back and forth with sizes in the TTM would add more stress?
Also what would you consider a 'small' powerhead, how many GPH?
 
Just a heads up if you need at tanks right now Petco has the $1/gallon sale going on right now. I picked up 2, 20 longs

Thanks! That's one of the reasons I'm trying to plan now, LFS sale starts when $/gal ends.

I have a koralia 425gph in my 20g long and it seems sufficient.
