I just thought I would share my great experience with finding this tool box / organizer at Home Depot. It's made by Husky and has removable compartments, stands on the top part so it doesn't fall over when open, and the handle locks it so that in case you forget to latch the front and pick it up, you don't dump it. And I've forgotten to latch it several times - it's still followed by the GASP!! and SIGH...
Here it is:
A close-up of the compartments:
Here's what I have in it:
Salifert Test Kits:
Plus all the sample and titration syringes, vials, spoons, color cards, and instructions
API Test Kits:
Plus all the vials (about 9 of them) and tops, and color cards
Seachem Test Kits:
3 sample cups
Razor Blade for fragging softies
Syringe for injecting Aptasia w/lemon juice
That part of the API test kit for holding the vials (cut out of the holder)
Stickies for marking water levels (to calculate water drop for PWC
1/4 C Measuring Cup
And I'm sure there's something else in there.
There's an empty space in the lower half for a full sample cup, I can squeeze another in if I need to by re-arranging the kits, and a third in the holder that they're in. Nice since I maintain 3 tanks.
I also was putting my Hanna pH/TDS
meter in by the refractometer, but the storage solution slowly leaks out, so now I keep it vertical.
Just had to pass on the wonder kit of all test kit organizers!!
