clearing and mounting after in situ hybridization

Dear Fellow Daniologists,

I have two questions about the best way(s) to prepare wholemounts of
zebrafish larvae for photography after in situ hybridization:

1.  How do you RELIABLY inactivate the alkaline phosphatase once the color
reaction has gone far enough?  Even after washing in TE or PBS with
Tween-20, we observe subsequently a diffuse staining everywhere, including
the yolk, that obscures the actual signal.

2.  When do you choose glycerol, benzylbenzoate/benzylalcohol, or
methylcellulose to mount for photography?

Thank you for any suggestions,
