Mass Coral Death

If I read your post correctly, you test after a water change
I prefer, and recommend, you test your paramaters before a WC

Personally, I like to know what's been used and other stuff before a WC so I know what is going on and what I may need to do to keep the Big 3 stable
Earlier in my venture, I also tested a day after a WC to see what was up

Testing after a WC doesn't give you enough info as it's just what you've changed now, not what's been going on in between the changes

Maybe others have different opinions, but, when I'm adding New Salt Water with readings of 10-11 Alk, 450 Ca and 1400-1450 Mag to my system, it makes a difference to me how much and how often I do WCs

Changing 15% bi-weekly is very different for me than when I do 10% weekly
This is because of my NSW content

Hope this makes sense, I'm tired and off to bed

So, my approach now will be:

• a good ro/di
• digital pH meter
• copper test kit
• ammonia binder

Anything else pressing?

I'll test again tonight when I get home. I have water prepped and will be 24 hour old by then so will do another smaller water change. Probably 20% at most.

Thank you again for your help! Everyone looks alive this morning so it's already a better day than yesterday.

Does your test show zero nitrite and ammonia? How are your fish?

No they aren't but I have filter mediums in for both and dosing with binders now too. I have Nitrate Destroyer and just picked up Prime yesterday.

Trigger died Thursday morning. The rest are all doing fine, so it appears. Trigger looked fine the night before was up trying to get algae out of my hand, was eating, etc. I have the QT out and ready to go, water made up, etc. just in case.

I didn't test today but will again tomorrow. Everything appears to be perking up. Clam still looks fine internally and none of the snails are hanging out near it and the wrasses are leaving it alone.

I might be on the upward slope again. Hoping...Thanks again!

Get some Stability too. Test every 4 hours and if tests show ammonia and nitrite is going up add more
