ALL Sps dying help please emergency

[fragbox]

Customers tank
300 gallon sps dominated

switched from 2 part to co2 reactor

turned it up from 1bubble /sec to 2 bubbles
this morning all sps dead or dying. Complete bone white
the ones that are still alive are peeling or super stressed no color

nitrate 5
phos 0
nitrite, ammonia 0
calcium 450 alk 9

what could be going on?
how to rectify?

deff sounds like the reactor was the variable. poss that there was some contaminate in the media or reactor itself? try running GAC. but first do a big waterchange

You didn't mention PH ? To much Co2 can drop the ph.....

 

[ct_vol]

I expect there was a large swing in one of your parameters. Doubling your CO2 bubble count overnight was probably not the best idea.

 

[Peter Eichler]

Doubling the bubble rate from 1 to 2 is a huge jump... Why do that when parameters are good? Were parameters out of whack before the readings you listed?

+1

Generally if the reactor is to blame, the only two parameters it could change are alk and Ca. A jump in Ca probably wouldnt cause a quick death in the tank. A large spike in alk can cause rtn. Your tank had a crash overnight and thats hard to do in a 300 gallon system overnight with two bubbles a second. The best way to calibrate a reactor is measure the pH and or alk on the out flow. Bubble counting is guess work that doesnt always represent a corresponding result in effluent.

Measure alk and Ca in the tank asap and see where its at before you do anything else.

Thats a crappy morning

 

[groentje38]

sounds like PH to low

 

[leveldrummer]

There probably wont be much you can do to rectify this. Tank is crashed. get what you can and save it.

 

[porsche908]

turn off the reactor which I'm sure you have already and make giant water change take out the dead coral turn up the skimmer. good luck

 

[Dog boy Dave]

its your ph man. The co2 from the reactor is getting out in your tank and dropping your ph. Increase flow.

When you get it figured out, make sure that the any excess CO2 from the reactor does not get into the tank. Drip the effluent back in so that extra CO2 can just escape into the air.

If you do this, then even a PH of 6.0 won't be able to swing your tank enough to crash it.

Diagnosed:

Clam spawning
not sure about the science behind it
killed about thousand of $ of sps

 

[brett7768]

that doesnt sound right at all

Ditto, I had an 8 inch clam go off in my tank. What the fish didn't eat the skimmer and socks took care of, no issues whatsoever.

Clams spawn either because the quality is good. Or really bad, i think the later. The claim only shows the problem, but it didnt cause the problem (might have sped up)

What was the water parameters before u adjusted the reactor?

Interesting. Mine did it recently when my Alk and Calc leveled perfectly where I wanted them. It was a big squammy that spawned, but I also had a Derasa that show enormous growth in a few weeks after my levels were perfect. Maybe the good parameters started everything going? Freaky clams lol

I have had multiple clam spawns with no issues to the tank.
