Kalk ?

[sparky0028]

I was speaking with the lfs about the use of a K-reactor and advise me not to use one, that I sould be using a dual chamber C-reactor. He point out that there would be extra calcium hydroxide and would start to melt the corals, that I should be using CO2 with the Kalk. I have read a lot of threads on this board about the use of Kalk, I am confused can someone clear things up for me.
The only reason I would actually think this could be true is that I have notice a patch of xenia that has totaly receded and also a area of my GSp has not open it the past few days.:help:
The K-reacrtor has been running from 5/12 topping of about 2.5 liters per day.

Thanks Kip
Thats what I though, but what I don't understand is why am I seeing problems with the xenia and gsp. I also noticed last night the my gorgonian's are not opening up either.

I had to move the drip tube into the main tank just over the returns becasue I did not have enough flow in its original spot and was getting a film on top ofthe water. Maybe the return was forcing the the kalk mixing over the effective corals?

The reactor is 30" high with the fresh water entering in at 9" about the kalk sediment and exits at the top. I have a pump that stirs the kalk up every 6 hours for five minutes. The Liter Meter pump was set for 2.5L per day which is about 16.6ml every 9.6 minutes.
I have not change the kalk out since I started on 5/12, and added 3tbs three time since startup. Why do you have to empty the reactor?:notsure:

last time I check the kalk stirred up to where the water enters about 9-10 from the bottom.I will look tonight.
I placed my water entrance up from the bottom because I though it might get cloggged from the kalk paste. Should I move it to the bottm?
