Something in my tank just isn't quite right...

[Jfish]

No expert here but it does sound like your moving too fast. Did you get fully cured live rock that you moved over from an existing mature tank? How much live rock do you transfer over and was it kept in water the whole time/not exposed to winter?

Being not exactly sure on the maturity of the previous tank if sounds like you have a lot of fish already. I would also cut back or stop with marine snow since it can pollute tanks very easily. That stuff can cloud up the water right after introduced but it could easily be something else.
