What is going on with my tank!?

[ReefJunkie]

I have been going through a cyano outbreak for the last few weeks.
About a week ago, after a couple good water changes, it seemed to be going away. Then one morning it was back in full force After that, I noticed there was no hermits around and untill now I've only seen one hermit and he was chowing on a dead hermit. But I also have 10 snails that are all still alive. At this point I gave in to the cyano and got some red slime control and dosed it yesterday. This morning I got up to find my cleaner shrimp dead and my water pink. My params---> PH-7.8 (been using marine buffer to get ph up) Salt-1.025 NO2-0 NO3-0 NH3-.3 KH-130.
I am currenty doing another 5 gal water change (29 gal tank) and just added new carbon.
Any help is much appreciated
