Calcium Drop??

[MizTanks]

Tested my water yesterday cal=440. Mixed up new batch=460. Just now checked tank several hours after WC and my cal=400. I tested it 3 times using API.

Where's my calcium? Kh=7. Ph=8.2

Not till I figure this one out......I am stumped so far. Hope to see someone with an explination.

Have you been dosing the tank w/ anything?

I saw you took out too much water and topped off with 1g fresh bringing you to 1.023 when you were at 1.025. The salinity decrease could be the cause and explain the kH being a little lower.

I had a problem in the past with my calcium.
I couldn't figure it out, until I started growing mass amounts of Halimeda. My gravel/crushed coral substrate was mostly the cause for that.

Now lately my calcium intake is such I only add it twice a week! I think my squamosa clam must have stopped growing.

Do you have any clams in the tank? I've heard that the gigas are enough that even a calcium reactor can't keep up at times.

Geeez sometimes I wonder if I even have 1 oar in the water-would a lower sg possible have something to do with a lower cal reading-sg=1.023 and cal=400?
