pc rainbow poof to white stick

[TheCamaroShow]

so I have a biocube 29 thats heavily modded and is a spa/lps tank. its a 4 year old tank thats very stable. i have 2016 apex, radion r15 g4, mp10, apex dos, tunze ato. I have a lot of acros and when Cherry corals did the last sale I picked up a pc rainbow and its been looking good for the past 2 weeks or so and I had a red planet on the rack and somehow my flow got turned down and I started to have some stn on the red planet so I came home and moved onto the rocks to get more flow. so a week later it was a goner so I was pulling it off the rocks and couldn't get it off so I pulled it out of water and got it off and my berry blast acro went flying to the floor about a 5 foot drop. so that started to stn and that was next to my pc rainbow and then today i find a white stick when it was full of color and pe yesterday.

You might need to go pest hunting. whats your alk at also and how often are you testing for it. I would suspect either alk or pests.

+1 always good to quarantine acros
