I use fluorescent tracers for leaking test in concrete and steel tank. Some of the tracer are NSF-61 and biodegradable witihin few days, no visible color. I do the test during evening and check with a UV lamp for leaking points.

The tracers come in powder, liquid form ready to use or concentrate depending what kind of product is in the storage tank.

Give me more details maybe I can help you out.
