That's crazy. When was the last time you tested before you noticed the drop? Could this have been a trend over a week or two or was this a sudden overnight kind of thing? You said you had been behind on water changes so I think I already know the answer.
Chasing numbers can make you crazy!
That's why I stopped.
If you trust your salt mix and you do regular and substantial water changes, you should be good.
The remedy for most problems is a nice water change
I agree and I do not prefer to chase numbers, but I also don't prefer doing big ass water changes regularly
Plan is to do water changes to bring my alkalinity and calcium up to proper numbers, figure out my dosing requirements and dose. I'll do smaller water changes.

After the 36% water change salifert alkalinity test kit says my alkalinity increased to 7.3 dkH.
I allowed 48 hours for the new water to fully mix with my old water before testing.
Depends on who you ask. If you kept alk at 7.3 always I bet you'd do just fine with most stuff. "Ideal" can mean lots of different things. Some people go all the way to like 14...
It is true, there's no hard and fast rule of what value it should be kept at. Michael, what do you shoot for as being an ideal alkalinity level for your tank?
Uh oh enderturtle got a hold of some primo nice shelf rocks. About to start improving not re-doing but IMPROVING the aqua scape! Redoing aqua scapes = bad! I can never rebuild things the way I want it. And I promised myself I wouldnt re-do the aqua scape entirely.
This rock came from a system thats super old. Lots of sponges, feather dusters, bugs have lived and died in this rock.
Since Im not interested in a nitrate phosphate bloom, im going to cure it in rodi water with a heater and powerhead. This will allow the nutrients to break up and leach into the water and not my tank.
Let it cure for 2-3 days will test the ammonia levels. (No bacteria = only ammonia). If nothing shows up then Ill start adding some to my tank.
I would do that if I saw a lot of organics on this rock, but it's mostly white rock.
If the ammonia levels skyrocket and don't stop, then I'll use bleach but I'm predicting it will not be that bad
The original rock that I started my tank with was covered with pest algaes, gorilla crabs, etc. it took well over 2 weeks to cure that rock.

Ammonia levels in 5 gallon bucket with dead rock and RO water.
Calling it around 2.0ppm which is not that much considering I've been curing this in 85 degree water with a power head for the past 2 weeks.
Going to do a water change for my tank and change out the freshwater with old tank saltwater to allow for:
More ammonia and phosphates to leach out.
Begin cycling this rock to allow for beneficial bacteria growth. (My tank water has bacteria)
Some people like to add a piece of cycled rock and I'm sure t has more bacteria than just water but I'm not in a hurry to get this cycled. Mainly concerned about nutrient export.
A mixed reef is hard to keep everyone happy. I believe a 40b is too short to have different enough light levels for softies n sps. That's why I have a softie tank where my zoas n mushrooms mostly are.
