Kalk in ATO

How many of you guys are adding kalk in your ATO?
I'm getting tired of adding 7 spoons of kh buffer and 5 spoons of Ca every day.

 

Through my kalk stirrer. There are easier options. I have seen some people have kalk in the reservoir with a small pump to stir up kalk every few hours. You can't add the powder directly as this will cause problems, particularly with Mg.

 

I am getting 15L of evap a day. So wont it be enough adding it through the ATO?

 

+-1500 liter
My evap has been constant for over 2 months. Well might be a couple of ml variance, but not allot different

Tank is fairly new(Around 4 months) but adding around R2k of additives a month is a bit mal if you know what I'm saying.

 

Will give the kalk a go and see what happens. Well at least a lot cheaper so dont have allot to lose.
Dont have allot of corals now, just a couple of softies and some LPS.

 

Ok here is a question. Have anyone tried "pickling lime" directly from the grocery store.
I hear it's exactly the same as the kalk you buy at the lfs, just a way lot cheaper because it's not branded.

 

If I guess five spoons of Ca to be about 25g, your "couple of LPS" must be growing like demons. Have you checked your test kits just to be sure?

 

Yes, checked test kits at the lfs. And yes the stuff is growing like deamons.

 

None. I mix the 7 spoons of kh buffer with RO water and add it to the sump immediately. It's not standing around. Same with the Ca. Well started with Kalk to the ATO last night so will see if that will help

 

Ok even with Max mix of kalk Kh and Ca is still dropping.

Would a new tank with lots of dry rock consume that much Ca and Kh? Surly cannot be the corals

 

You can see the tank here

Explain what you mean precipitating please. Maybe my idea of precipitating is not the same

 

How would that happen and how can I prevent it.
Think I can mix like 2 spoons kalk with like 200ml water and add it directly to the display where there is high flow?

 

Well there is dust lying around, but that was from adding more sand to the dsb. On the return pumps there is some white. Those pics are old though. The corals are more than double the size now. How can I stop the precipitate?

Also, my sand sticks together like it's making it's own rocks. I do break that down often
