Spring coral losses

[GreenSpottedPuffer]

I just pulled out half my sps in the past two weeks. Most of it went yesterday.

I had low ALK for a bit but everything seemed to get through that. Then a few weeks after getting the ALK back up, I have lost a bunch. Maybe was the ALK but I don't know...doesn't seem like it.

All kind of an STN thing. They would one day start to loose polyp extension and then the next get pale and then over the next week or so start to go.

Levels in the tank are testing fine. My PH is always up above 8. Anywhere from 8.2-8.5

Alk has been steady right at 8.

Can't find any pests. Pretty sure thats not it.

Frags I have gotten from friends or other reefers are all fine. Old stuff I have had for a year or more is fine. Only stuff I have bought in the past 6 months or so has died. Might just be coincidence though.

LPS is fine of course. Although I lost a candy cane colony.

Who knows! But it really has me turned off of sps for now!
