You might be able to add (or paint on) something which absorbs UV strongly, but doesn't fluoresce.

Does it have to stay water clear?

What about adding dibenzylideneacetone? It is used in sunscreen. Slightly yellow but it is non fluorescent.

Yes..it is better if it remains.
I thought uv absorber could be helpful..but don't have uv absorber.

Can you buy sunscreen and see if it helps?

Potassium iodide is a fairly good quencher for Fluorescein in solution that i have used in the lab before. It would probably work for you
