I had 2 almost 3 sps corals die from a ph swing. Now my cal is 500 how do I lower it. I've done a 25 percent water change.

The calcium level at 500 is ok. Don't worry about that. The water changes will bring it down a bit, but it will not kill your corals. What you need to be concerned with is your alkalinity and your magnesium. What are those levels and your current ph?

ph swing. Now my cal is 500

those should be unrelated. Whats your alk? No3?po4?

 

[ironman20725]

One min! I'll get those numbers

 

[ironman20725]

Alk is 9.9 ph is 8 mag is 1380

 

[ironman20725]

The only thing that dying is my acro's

 

[saltyfilmfolks]

how do you know it was a ph swing?
What are you dosing?

 

[ironman20725]

Like the ****** I am I put an co2 scrubber on to help my acro's

 

[ironman20725]

And I dose brs 2 part by hand

got it. Awww Poop. Pull the scrubber and hit the surface with a powerhead the PH will equalize.

Did pull the scrubber

Did pull the scrubber

Not 100% sure there's anything else you can do.

Lets tag the rest of the #reefsquad

Just leave it alone the cal will drop on its own and the alk. Watch the Mg and dose when you need. I would skip this week's water change too help the parameters fall back in line if you are use a salt with high alk and Ca. If you need to do a water change grab a small amount of at different brand with lower alk, Ca to help bring down the Ca, Alk while keeping the water fresh.

As far as PH 8, is fine. Is your house closed up all the time? If so you might want to looking to running a airline from the outside to your skimmer or add a PH scrubber link another trick I also use in so have a lot of surface agitation and run a fan

What type of salt are you using? if the salt has a high alk and Ca this will also drive you parameter up and if you need to do a water change grab a small amount of at different brand with lower alk, ca to help bring down the Ca, Alk while keeping the water fresh.

I bought a ph scrubber that's what kicked this all off. It jumped it to 8.5 in a day. I just use ocean crystals

 

[mtraylor]

Yes you need to just let it stabilize now. Hopefully everything will be ok. If some of the sps dies off, it may make a comeback. Fingers crossed for you.

You use reef crystals? that is were your high alk and Ca are coming room. IORC is produced to run high for faster growth. You could use IO sea salt which has lower parameters in the mix to help lower the Alk and Ca

What Was your calc at before it reached 500? Size tank? And what do you mean by ph swing, how large was it compared to your normal daily swing
