Dead Milli

[tidefanjam]

This guy was ok yesterday, then this morning nothing but bone...?
Everything else looks good, just tested water..
Alk 9
Cal 415
Nitrates 5
Phos 0
Sg 1.026
PH 8
I know that my phosphate is too low, would that kill it overnight? Tanks been up 20 months, only think I’ve done different is started adding Kalk in my top off water, I have a small return in my sump, which is where my ato empty’s into, also this Milli is the closest to my return pipe, could it have gotten blasted with to high of ph/ alk before it had a chance to dissipate? I added some more pics, everything else looks happy, even the acro near this one

Well, my pic posted backwards, dead one is last..

When did you put the milli into the tank?

When did you put the milli into the tank?

About 3 weeks ago, same time as the acro behind it.

I don’t think low phosphates would do it. I would suspect kalk. I’m a big fan of kalk and have used it a long time. I add it very slowly with a liter meter 3 over the course of a day. I would try to add it more slowly if possible.

Kalk is my guess

I’m pretty sold that it got blasted with Kalk, my level probes on my innovative marine top off quit working so I’ve had to manually top off in the morning and evening, I believe the larger amount of top off water caused it to get hit with to high of a PH, I have a spectrapure ato ordered and in the meantime I’ve moved my ato outlet back in my sump to the first chamber so it will mix with more water before getting pumped into my display.
