SPS is dieing

When I do my water change which is every two weeks I add this nutrients

What salt are you using Red Sea Coral Pro? That's the only salt that I've ever use with that high of dKH.

Yes red sea coral pro salt

IMO the alk is dangerously high, coral killing high. Combined with the unnaturally high ca, I suspect high salinity. I'd slowly adjust alkalinity and salinity to natural levels (7 and 1.026) before anything else.

Yes red sea coral pro salt

That's what I figured. Not suggesting changing salt at this point, but if you want to keep your dKH lower than 11, you'll either have to change salts or use acid to decrease the fresh mix every time you want to do a water change. But that's not something you have to decide at this moment, just food for thought.

I was using Red Sea Coral Pro and stopped using it because I didn't want my dKH so high. Wanted to stay closer to the 8dKH range.

At the point of where the SPS look, like said before they look to be almost completely goners. Hopefully you do not have a lot of SPS in the system and can recover once you get nutrients lower. You have the chart I posted from LiveAquaria, so you can use that to determine what works best for your style of reefing.

He will need to change from Red Sea Coral Pro salt if he decides to decrease his dKH below 9. If not, every time he does a water change he will have big dKH swings, which isn't going to end up well either. Sticky situation.

I


It’s depend on the sps some have die quick some are dieing slow

I rearranged my aqua scape can it be that

Yes if you stirred your sandbed and you haven't always kept it clean, you could have released a time bomb in your system. If that is all you have done and the lighting change didn't cause issues, I'd say that is the cause. Sand beds are good until they are not good. Going undisturbed for a long period of time, then getting mixed around will cause these types of issues.

One of the reasons, more and more hobbyists are going bare bottom.

I use to use different salt

That or add some HCl to the new seawater. I can't find affordable salts with natural levels so I use io and adjust to 7 while mixing. I wish there were more salts available at natural levels

Fritz Pro is a good salt. Any particular reason you decided to make the change? I see you still have a box of Fritz Pro. Did you recently make that change as well? If so, a combination of going from around 8-8.5dKH to 11dKH, lighting change, and disturbing your sandbed just was too much for your SPS.

Another reason I just stopped doing water changes altogether honestly. I'll keep a box around if needed, but just will add the needed trace elements going forward.

Sometimes manufacturers of salt start to lack quality control and if you aren't testing your fresh salt mix (likely 90+ percent of hobbyists do not) something as a simple water change can be catastrophic.

Are you running a Calc reactor? I ask because your Apex says, "PhC" and is reading values typical of reactors. If so, take that thing off line, it's not helping your calc. or alk levels.

Yes I set a calcium reactor I haven’t been running because I am having high calcium and alk

I use the fritz for my qt tank

It was on same the RedSea salt fritz is a good salt I been using it since I setup my tank

Alk and CA is high
Others things that would cause this:
High salinity
High PH
too much water flow
Excessive white lights or poor lighting
Flatworms .

That’s exactly what happened, I try to do the aqua scaping mp60 air wasn’t blowing for the back so I made sure I have space from the back

Can it be I have 2 mp60 running

 

[vetteguy53081]

Can it be I have 2 mp60 running

Yes depending on percentage VS Tank volume

 

[hyeclass]

O

Yes depending on percentage VS Tank volume

It’s running 50% then 20% nights time left right 20%

140 gal RedSea reefer

2 MP60 in that sized tank it total overkill. You could get by with 2 MP40 running in ReefCrest mode at like 50%. Running 2 MP60 you'll need to likely run them at the lowest speed to not beat the living crap out of your corals.

I'd still point toward disturbing the sand though. If everything was fine prior to that event, that's more than likely the root cause and now you are getting advice on optimizing the system in general.
