This is huge. A huge drop in salinity could cause this for sure good questionI don’t think it can just go down without using up over 10dkh in alkalinity. You checked salinity?

I got the answer I was looking for. I'm back in the 400s. Feel free to delete the thread. It's no longer usefulIt is on topic to very strongly drive home the potential for it to be test error, because you will create a problem that didn't exist.
If you do not know how it got there, it is likely a test problem. Calcium does not just drop 200 ppm overnight.
It would take a massive amount of alk dosing without any calcium. Like about 30 dKH worth.
But, if it really is that low, I'd raise it higher than the normal rate because it is very stressful. Maybe 50 ppm per day.

So you went today from 200 back to 400 just like that with 1 huge dose and yet still don’t know how it got that low to start with ?I got the answer I was looking for. I'm back in the 400s. Feel free to delete the thread. It's no longer useful

It didn't drop 200 overnight. Over three or four days. My corals consume 30 ppm per day. Go see what Gbroadbridge wrote. He was probably correct. I dosed 100 ppm per day so two daysIt is on topic to very strongly drive home the potential for it to be test error, because you will create a problem that didn't exist.

I wish folks would admit an error, it helps others in the long run. Anyhow, glad you’ve cleared it up. Happy ReefinI

With wishes like that all your doing is preventing people from posting. I certainly won't again. On advise from another post in another forum it was suggested that I do a 50 percent water change to drop my nitrates. Just didn't take into account the new salt.

This is exactly what I was thinkingNo, a water change with Red Sea coral pro is not the explanation for your observation. That cannot possibly be the explanation for a 200 ppm drop over 3 days unless alk dropped 30 dKH (how could it???; was it ever that high?) neither is a salinity change unless it dropped from SG 1.026 to 1.013.
I am more than happy to keep trying to explain and get at the real reasons for this observation, but it does not appear that you are interested in further discussion.
FWIW, the likely explanations are alk overdose, or test error.
Hi, this thread has been extremely helpful. This happened to me two days ago. Accidentally overdosed alkalinity two part (human error not apex) which dumped 1.5L of the solution overnight in a 45g. PH shot up over night, killed all inverts and 2 fish (incredibly 4 survived) - leaving a dust storm of Calcium Carbonate all over the tank. Felt very bad for myself, then got into action to clean up. Two large water changes (40% first and 15% after) over 36hrs, seems to have stabilized PH but everything else is a bit crazy. Calcium dropped to 220ppm (from 450), Alkalinity is 14 (Don’t know what it was before wc) and Mg at 1250. Need some advice if you can on two things:No, a water change with Red Sea coral pro is not the explanation for your observation.

1. how fast can I build up calcium ?
2. will the left over calcium carbonate dust be harmful in anyway ? Cleaned up a lot with filter socks, but still have it on rocks, sand, parts of sump.
Ouch what was the error? Dosing quantity programmed in liters instead of milliliters?
General consensus is to rise CA no more than 50ppm a day.
The dust, not a clue
No. It was programmed well but a very basic program to dispense in auto mode. I noticed that alk was reaching 9.8 and turned off dosing for a day. And then when I turned it on, instead of putting it in “Auto” which goes back to table dosing, I accidentally made it to “On” and went to bed. Woke up to alarms of high PH and drained DOS. Stupid me.Ouch what was the error? Dosing quantity programmed in liters instead of milliliters?

Thanks. This is helpful. ALK is still high at 13. Can I drop to 7 without dropping PH ? If so, other than water changes what would help in dropping ALK ?The problem is that you have massive amounts of seed crystals of calcium carboante in the water just waiting for mroe calcium and carbonate to come along and precipitation onto it.
I'd raise calcium pretty fast (2 days), but you may need to allow alk to drop fairly low (6-7 dKH) for a while to break the cycle.
The particulates are not a concern aside the ongoign precipitation issues.
