I use the Hagen Master Test kit. Comes with every test kit that fits in a hard brief case... makes you look really smart.

People really go WOW, the hobby is hard hey, after they see all the test kits (little lab)

Also if you run outta one solution you can run out an by individuals.
Also for additives I use Kent calcium liquid, buffer milk, kent Iodine (makes xenia pulse more) and live DT phytoplankton. Then I use Selcon & Garlic Extreme for the food.
