I have a smallish wildlife pond that has a big algae problem (not sure its blanket algae - seems too ‘foamy’/slimy) would cloverleaf blanket answer and sludge answer work? I take it it won’t harm the tadpoles/spawn?

I use Cloverleaf Blanket Answer and Sludge Answer and both work well in my pond and does not harm the wildlife.
I would also skim of as much of the algae as you can manually as well.
With the Blanket answer the water will go a chalky white for a few days but soon clears.

You can also chuck in some watercress - just a bag from a supermarket if you can get it.
It feeds on algae etc, and helps clear water.
It's a place where beautiful isn't enough of a word....
