Help With High Kh

[chief hill]

Flame angel is going south. Everything else seems ok. FA right eye is cloudy and other one is ok. Put her in sump for now.
Tested water and found calcium around 380 and kh at 15. PH both with salifert kits. PH around 8.2 with API junk.
I ordered kalkwasser (haven't received it and won't use it now that I know my kh is so high) 30% water change was done a few couple days ago when I first noticed high kh. I dose nothing now and use IO salt. Salinity at 1.25 Any ideas?

Test your source water. Especially if your not using ro/di

I'm using RODI. It's only about 4 months old.

Won't hurt to test KH on your ro anyways. Then you know a base point

My lfs has a tang or a trigger that his eye goes cloudy whenever lvls get out of wack a bit, they say when his eye is cloudy it's time for a water change, almost like a pretest kinda like a visual test for them. Are all your other lvls in check? Ammonia, nitrates?

I'll test my saltwater Rodi storage and see where it's at as well. Good idea.

Tested the saltwater and it's off the charts. It stays blue on the salifert kit won't even change with 1ml? Wtf? I don't get it could it be bad salt? I don't run anything in the 30 gallon salt tank except for a 550 power head.

Bad salt is always an option but it's hard to tell. Hopefully you get to the bottom of this without losing anything :/

Start by eliminating stuff. Test pure tap water, test rodi water, you have tested the salt so now go until you you find where the jump is.

 

[chief hill]

Tested the RODI water and nothing happened on the salifert kit added the reagent and it did nothing. Should RODI water even show an KH on a test? is that why the color wont change?

Tested the DT and its now showing 12 / 12.5 which is much better.

No, rodi is supposed to be pure, should register 0 for everything

 

[Sewerat]

So either something going on with test/ salt, or salt mix tank. Now you know where to start changing things until you find a culprit.

OK well that's good then. My source water Rodi shows nothing for KH.
Now I'll have to figure out why my salt mix is also not showing anything for KH either.

Yea the test is OK. I checked with the solution that comes with the kit and it's right on.
Will test more when I get home. Maybe it's time for new salt.

Your Calcium is a little low and your kh is very high. The kh should fall on its own over time. Those readings do seem odd though. IO salt is certainly not my first choice for a reef aquarium as there are much better options and its not unheard of to get a bad batch now and then. I would let it run for a few days as is and then retest. If your at all concerned about your test kit then bring in a water sample and I can test it to give you a comparison.

Your newly mixed saltwater tests nothing for KH as well?

Thanks I will keep an eye on it and see how it goes naturally over the next couple of days. I'd love to bring in a water sample but the 2.5 hr drive would be rough. Lol. Thanks for the help.

I'll test when I get home and see. New Rodi saltwater at 1.024 has to show kh of some sort. Will advise this evening on my findings.

 

[chief hill]

Update. Tank is at 12.5 and Rodi saltwater storage is at 9.9

 

[Sewerat]

That's better at least

I would lower your Salinity and do some big water changes for starters.
