Low alk, low PH, high calcium

[Randy Holmes-Farley]

It takes a healthy level of mag and dKh to keep the ph right & steady. That’s what I’ve always done to maintain my tanks.

Magnesium has nothing to do with pH in seawater, and cannot ever explain an imbalance where calcium is high and alk is normal.

What it does do is reduce the rate of precipitation of calcium carbonate. That cannot cause high calcium.

I see. Thanks. Another reminder why I got a C in chemistry.

7 dKH is fine and is higher than the ocean, but if you want to raise it, it is easy to dose a little alk.

Don’t waste money and time on a bogus product like Sealab 28. It cannot possibly too what it claims.

I would not assume there is a calcium issue.

if you get to the end of the first syringe of Salifert calcium titrant and have not reached the endpoint. Start a second syringe, then when you get to the end point, add the two values together.

Thanks for the help. Noted on the sea lab. With the calcium test, I did try to add the values and if I went by the instructions would have about 650. I’ve always been very careful with salinity, I measure out properly and use a probe and compare with a refractometer. But, concerned about all my tests now
