Adding a couple fish is a good idea. Dinoflagellates are only toxic to snails, correct?

I'm sure instability started this. It's a relatively new tank and I am new to reefing. Figuring out what instability caused this seems to be tricky though.

a new system lacks chemical and biological stability right out of the gate because of all the varying stages your rock and substrate (if you have any) are at in terms of maturing.
a lot of progress can be made with just rock solid consistent feeding and resisting the temptation to change things.
dinos described are toxic to "inverts" and I can confirm snails are on the list but I'm not entirely sure if it affects crabs or otherwise.
there is no catch all solution for beating dinos which is why I recommend scoping them. from there you can at least make decisions based on others success instead of spending, causing instability and getting frustrated.
