Multi Element Test Kits are a good way to get all the aquarium tests you need in one hit. Often when starting an aquarium you have no idea what you need and how to get going. Buy getting a good allround basic kit you will have all the tests you need and the advice on what to do if a level if off. I can not highly recommend these kits and believe everyone who has an aquarium should know what is going on with their water. |
