Anyone have problems after switching to kalk?

Possible low DO(Dissolved Oxygen)?
What's your pH?

This is all fairly new growth, I had a misfortune with a faulty heater in January.
Wiped out 90% of my coral with a temp of 91 deg., I'm surprised my fish made it..
So I figured it would be a good time to try a more economical way of supplementing, since I'd almost be starting from scratch...

I switched back to Kalk after 10 years of using C-Balane and EcoSystem Reef Solution; Simply for economics..
I mix 3 table spoons of Kalk in one gallon of RODI and it every other day as evap.(pour off the clear solution into the sump near my skimmer intake)
On opposing days to Kalk mix, I use Strontium Chloride(2 Table spoons in one gallon), and Bright-well MagnesIon-P(2 table spoons in one gallon)

Weekly I add NF metals, Potassium, and 5ml of lugol's (This was part of my supplementing before switching back to Kalk)


120 Gallon Mixed Reef

NO3 - <10 PPM
PO4 - <.1 (Note: before using Kalk PO4 was .1-.25)
CA - 420 PPM
MG - 1470 PPM
SR - 16 PPM
DKH - 10º
SG - 1.026
pH - 8.6

Not sure about the dissolved oxygen and forgot to check PH last night. I have not had ph problems in the 7 months or so this tank has been running though.

From what I understand its hard to increase calcium and alkalinity unless you're using concentrated kalk. I accidentally dosed 3x my daily consumption on Saturday at full saturation rodi. It had no impact on calcium or alkalinity. My Ph did rise to 8.72 though which probably should have killed a bunch of stuff. So far I haven't lost anything, and the effects may not be seen for quite a while still.

Paul B. your tank requires its own entire forum because it runs differently than anyone elses on the planet.

Actually my tank runs the way all tanks used to run, then someone invented the internet and now every one's tank is the same. :dizzy:

I nearly lost all my sps when I started kalk. But it wasn't until about 3 months into dosing it. Montis were the first to show problems.
