Brad it realy work I do it for a long time europeen people either and it work

most europeen tank have those kalk reactore they are a way more popular then in north america and they know them well I do either as I have it for long time and use it alone do dose my calcium and buffer it is not blind dosing when you know how it work and realy do it the right way

Stephane, perhaps it works with the reactor, but Mason doesn't have a reactor. He is mixing kalk and putting it in his sump, and I'm not sure he knows why he's doing it. Maybe 'cause it's the popular thing to do.
I dosed kalk for the first year of my tank and if I didn't test regularly, I ended up with problems. I had to always balance the levels with Kent A + B .

Steve IMO you got this problem cause you didn't monitor well you ph and add to much kalk at each time kalk need to be drip and alway monitor with PH

the magnesium pricipitate when the ph is to hight if you add one liter in the sump the ph will climb up to 9 and then go down there you will have precipitation

Kalk is good but if you mess you will crash calcium reactor will crash a tank either but there more documentaion to know how to not mess with it than kalk

I read on farming and there a lot of coral farmer use only kalk for many reason

Stephane, can you point us to that reading? I'd be interested in it. Reading a lot of Eric's stuff, he maintains that sleletal density is affected by using only kalk (incomplete calcification?). I haven't read enough though, so if you have some links, that would be great!

I have not include the link I was talking on the calcim balance on the previous tread sorry here it is read it before to do any dosage http://www.advancedaquarist.com/issues/nov2002/chem.htm

yes brad you are right that why I give this link and tell to study this well before to do it and tell him to not test only when he know wath he do

it dosnt realy matter if you have a kalk reactore or not as long as you use fresh kalk and dont cross the PH warning maybe you have and that why I said you NEED a ph meter to do it

if people dont do it the same way I said you will have problem
before to use any methode you need to read the instruction if one dont and have problem it's not the fault of the product :D

who is the coral farmer in US? Antony Carlfo simply ask him he said in is book a lot of coral farm do it and he does but he dont use reactor only drop milky stuff in is tank but dont do it at home until you realy know wath you doing!
BC and Son before to kalk addition as people have warn you you should realy know wath you do before to add it in you tank

Hmm, I read that book and didn't see that part. I'll re-read it today. :?

page 181 to 186

Wouldn't adding all these additives also depend on what kind of corals (and other co-habitants) one would want to keep? :?

Not to pick nits, but I beleive "he" was actually a "she", who said it first here ... :P
