That's why I don't use anything, so I can see the eggs. Further I find it easier to control - size of spawn, success or fail, scoop out eggs for artificial hatching etc. And since I've been doing this for quite a while, I know how they would act if and when they're done.
Sometimes (for more sensitive males) I cover half of the tub/container. The male will nest under that dark area. Though I can't clearly see, but the eggs will be visible. I try not to disturb with flash lights etc.
