question how should I leak test my new 210 gal reef tank. Should I fill it with salt water, or RO/DI water or just tap water. how long should I let it sit. If I use Ro/Di water can I then mix my salt right in the tank or if I use salt water and it leaks then I waste all that salt. If I use tap water and there is not leak then I have to empty it all. what should I do?
