That's what the guy at the LFS said but he saw it with his own eyes. LolNo more than 50 ppm per day, but I agree, something isn't adding up. I don't even know if its possible to have a reading that low.

Everything looks fine. A freaking mystery. I raised it 100 ppm per a post on reef central. Well see how they look tomorrow. I lowered the lights significantly until this is resolved. Less light less growth less looking for calcium and carbonate, I'm hoping.Is there precipitation in the tank? How do your corals look?
I've always heard don't change alk more than .5 and calcium more than 50 per day.
I don’t think it can just go down without using up over 10dkh in alkalinity. You checked salinity?Everything looks fine. A freaking mystery. I raised it 100 ppm per a post on reef central.

1.026I don’t think it can just go down without using up over 10dkh in alkalinity. You checked salinity?
Can you check some freshly made up saltwater, for calcium?1.026
This was my original thought .No more than 50 ppm per day, but I agree, something isn't adding up. I don't even know if its possible to have a reading that low. What's your ALK at? K, just saw, your Alk is at 9.5 DKH.
@Randy Holmes-Farley
Done 1.026Doesn't add up.
Check your salinity and check the calibration of your salinity measurement device.
I wouldn't just significantly raise Ca without independant verification of both Alk and Salinity
Done. CA red sea coral pro 425. Supposed to be 450 at 78 and 1.026 according to label Did a 20 percent water change. We'll see tomorrow AM what it reads. Corals all look good so we'll see tomorrow.Can you check some freshly made up saltwater, for calcium?
Yes last Sat I started red sea coral pro salt. Did a 50 percent water change because my nitrates were at 20 ppm. Tested afterwards all parameters were fine. CA 450, dKh 9, mg 1350. I usually lose 30 ppm ca/day, Alk 1.5/day pH buffered at 8.2-8.35 swing per dayHas anything change is your aquarium setup recently? New equipment, new media, manufacturer change in media, dosing, or supplements?
Let's stay on topic. How much can I raise Ca in ppm a day?
I don't think it matters. I would just spread it out over a day to prevent precipitation where you dose it. It's not like calcium is going to be toxic or affect pH or anything.
