RTN, Bilpellet Reactor or SPS Stinging ??

[LittleMaui]

My prize pink lemonade turned completely white in a matter of a couple weeks. My nitrates have been around 10, so I decided to add a biopellet reactor. Now I have a strawberry shortcake dying quickly (see picture). My nitrates haven't changed. What do you think? I also have a tri-color that looks stressed, turning white from the base. On the shortcake and lemonade the zooxanthellae died quickly and coral turned bright white.

Can other corals kill each other? The lemonade is being touched by another shortcake and the strawberry is being touched by green slimmer. Both in the area that turned white first.

Stats:

pH 7.9 recently dropped to 7.6

P04 . 06

dkH. 8-9

Ca. 450

Mg 1300

Potassium 420

Salt 33

NH3 00

N02 00

I’m afraid your tank went through a swing parameters.
Did the recession happen before your large drop in Ph?

 

[LittleMaui]

Started before.

Still I think you encountered a swing of some sort.
Can be ALK, temp, SG or Ph.

Seems logic dictates the biopellets are the root. Shut em off.

No need anyway - your levels are fine.

Just grow more coral and use up those nutrients!

I am just going to through this in.

I had a situation like this and couple a month back, it came down to dosing too much Ca, Mg, alk and one of my wetside pumps cracked and was rusting.

We are all throwing things at you to check

You definitely had a swing I had this happen a few months back after a tank cleaning vacuuming the substrate. I then started losing corals I now use my DE filter when doing this type of work on the tank.

Try to raise that n03 if possible. If it is truly 0 then that could cause some issues. I am not sure that the alk swing of .3 would be the culprit. I’m not an expert either. I have heard that with zero n03 you want lower dkh too. But again I don’t know for sure on that.
