I found this on some test kits.

So far I have not added anything for alkilinity.
To date my Ca is around 340 ppm and my alkilinity is still around 250ppm. As I gained 140 ppm on my calcium I did loose 60 ppm on my Alk.
I have read in pultiple places that this offsetting can be expected. However no one realy puts anything out that I have seen as far as a relationship between these offsets.
When the alk is down I'll probably start adding it in the form of baking soda untoill I get a Kalk reactor going. Then hopefully the Kalk reactor should take care of keeping the Calcium as well as the Alkilinity up. I do expect to have to do a little additional dosing of Calcium Cloride even with the Kalk reactor.

Dennis, I am going through a somewhat similiar problem. I have been dosing Turbo Calcium for a couple of weeks and I can't get CA past 330. I have a 72 gallon tank and I have poured in 8 tsp which is what the handy dandy calculator came up with and I am still at 330-340. I started a post in the Chemistry forum. The wierd thing is, my alkalinity has shot up to a high of 7.5 meq/L!! I have a very simple tank and the calcium is not being used up that quickly. I did my tests with a NEW Salifert Calcium test kit and a NEW Seachem PH/Alkalinity test kit. I have not added any buffers during the Turbo CA additions.
Long story short I have new test kits coming from different companies and I am checking my Magnesium levels.
Good luck! I hope we both find solutions to our chemistry issues.

Well with the Salifert test kit I was holding good number or only a little high on Alk. Ca was 420 and Alk was 200 to 240. Then I did not test for 3 weeks and started testing with an AP test kits. Numbers changes to 200 on Ca and 320 on Alk.
Since I moved up to using 15 tsp per day of Turbo Calk it sems like I'm gaining 10 ppm of Ca per day and loosing about 10 ppm of Alk every 3 days.
things are moving in the right direction only I need to get some Calcium Chloride ice melt as it is much less expensive than the Turbo Calk at the rate I'm using it.
Note 15 tsp per day = 100+ per week or over 500 grams or over a pound per week. Sure I won't always be using this much but still it is cheaper.

Why are you so resistant to tell us if you test magnesium or not? I think you've been asked 3 or 4 times now...:lol: Anyhow, if you need some Peladow let me know, you can come get some from me while I'm spreading it all over my sidewalk tomorrow

No I do not have a magnesium test kit.
Spent most of last night hitting store after store localy looking for Calcium Cloride. Only found to simular products.
Fire and Ice on the label it is a blend of Calcium Chloride, Magnesium Chloride, and Potatsium Chloride. I do not want to add Potaatsium.
Then there was Prestone Ice Melt. It did not list any ingredients but gave a warning about Calcium Chloride being caustic.
Has any one used the Prestone Product? And if you use Peladow where do you purchase it?

Read randy'2 two part Thats what I use.Prestone is fine just a little more high on the calcuim i think

Totally agree almost everytime I see a thread like this where turbo calcium does not work it is low magnesium levels. A few time alk is to high.
At the rate he is dumping calcium in he is going to have calcium build up in everything.
Salifert test kits are not what they used to be. I do not know if they have quality control issues but I keep hearing of bad batches. I have tested new kits against old kits and way different readings...
I had used them for years and no issues but I am done with thier Calcium and alk kits...
Dennis test your magnesium before doing anything else.

Well I spend the weekend hitting numerious pat stores picking up test kits. Did not find anyone stocking a magneesium test kit but there are few shops I still need hit.
An interesting thing though on results.
Alkilinity
Aquarium Pharm kit = 240 ppm
Red Sea Kit = 100 ppm
pH
Aquarium Pharm kit = 7.9
Red Sea Kit = 8.2
Calcium
Aquarium Pharm kit = 320
Salifert kit = 440
Red Sea kit = 410
I'm starting to think the Aquarium Pharm kits are the least accurate at this point. Through the past I had not been dosing enough and with the catchup probably did get the calcium in proper range but my lost on the alkilinity and magnesium.
I'm moving to the three part dosing solutions mentioned in the article that someone thankfully refferenced. I put added columns in my spread sheet that give the proper amount I need to add of each solution to get a balance based on four equal dosages to limit sudden changes and keep things moving in the right direction.
As a little side note I had noticed that different individuals or companies reccommend different levels on the chemicals. For example I found recomendations for Calcium at 200 ppm. anything over over 300ppm, and 400 to 420 ppm. Then for Alkilinity recomendations of 100 to 150ppm, 200 ppm, and minimium of 240ppm.
The goals I'm going to be striving to hold are:
Alk 200ppm, Calcium 420ppm, Magnesium 1,200 ppm.

I second that!!! Now I just need to add some of that granular Mg to mine (KZ and fauna make it) to boost my Mg. My alk is steady at 8.2 dKH, and my Ca at 420ppm, which is good, esp considering my Mg is at 1050!
The other odd thing I found was when I did my iodine test... my iodide levels were right on... .03-.05, yet my iodate levels were nil! 0! Usually, its the other way around. I found this very very odd. I almost wonder if its just a Salifert thing. Wonder if it wouldnt have anything to do with some of my zoas looking rather 'meek' recently.

Could be those little starfish as well... I suppose they do munch on corals.

Well I do have a dosing pump and Kalk reactor on my Xmass list. Now if only one of my Santa Clauses are good to me.
My thoughts are the Kalk rector will add both the Calcium and Alkilinity I need with just a minimal amount of additional dosing required.
As far as my zoo go there looks are mixed. Some of them look fantastic while others are just not opening.
Red Fringe brown centers looks good but spreading very slow.
Green Fringe brown centers looks good but spreading slow
Blue fringe blue/gray centers growing like nuts
Blue fringe red centers just barely opening.
Now if Alk should be at 10dKh then the 200 ppm goal I thinking of holding is probably way to low. I have not heard any shortcomming from having to high of an Alkilinity so perhaps I will push it a little higher.

I love my calcium reactor. It makes life sooo much easier.

Dont go above 12 dKH, at that point, stony corals cant absorb calcium.
