magnesium

What does everyone use to dose it? I haven't been monitering it but for the past few weeks I have had a drop in calcium and alk levels and I believe its due to a low mag level.

Can you get a test kit? My calcium & alkalinity always drop but my mag stays pretty consistent. I use salifert tests for stuff like this, it;s very important so a good kit is a must.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.

I do weekly water changes to keep mag levels up.

I tweak mine a bit now and then with a mixture I made up. I only do 2 water changes per month and have a very high coral load, so I dose Kalkwasser and a bit of magnesium solution. Works for me.

I change water every week on the dot but I haven't been measuring my mag. Why are my calcium and alk levels wanting to drop. I don't see any precipitation. Is it possible that my corals are using it up. I am gojnf to get a test kit tomorrow the store today didn't have one so we will see. My alk will go from 9.3 to 7 in a week and my calciim will go from 420 to like 380 in the same time. Have u had this problem x or carey

Yes, my sps is growing very quickly. I'm definitely using elements.

Yep, the corals will eat up the elements and your levels will drop. I have more of an issue with alkalinity which I will dose every few days with soda ash i got from BRS. My calcium doesnt drop as quickly so water changes seem to work for that and my magnesium hardly every drops between water changes so i test for it but dont dose anything for it.

I looked at my heater today and saw some precipitation for the first time. All my coral are babies I have a lot but still they are a small. I would be surprised if they uses all those up I'm wondering if the trace elements are staying to a good level with just water changes

I don't add anything manually, and everything is growing just fine. I've also kept sps dominated tanks with just water changes.
