Kent tech cb .....confused...help!

[miserkris]

Hi
I have 75dt....with 85g sw volume....a mixed reef
I've been dosing kent tech cb part a&b for a month now...
Like 15-20ml daily.

Today I tested with api....dkh is 7, ca is 460.

Which of the kent marine tech cb should I reduce ?....since ca is fine, but alk can reach 8dkh....

I think I should reduce or stop the tech cb partb ....right?

Or do both parts a&b, always go together...in equal portions?...since ionically balanced.?

Btw, I just started adding kalk to top off ro water too.
Pls advice! Thanks

I would stop the calcium part, and keep adding the alkalinity part. That's a fairly common sort of tuning to have to do. It's worth making sure the test kits are working properly, if you see any signs of problems with animals, though.

+1 on what Bertoni said.

Reduce the Part A (calcium) and keep adding Part B (alk). If you are adding Kalkwasser, then that is doing some of the work that Pt. A does. Just take it slow and easy and keep adding Pt. B. I am in the same situation as you. My numbers are just about the same. Don't forget to test your Mag too.

Thx both!
Can I add part b slowly over 15mins ....with lights on?
Partb is the white milky liquid....so if thats alk I will dose part b. The confusion is the bottles don't clearly say which is ca, or alk.

So, I mixed kalk 1 tsp per gal.....for all night long.
Then pumped into ro reservoir from the middle section of my brute 32g can....still the mixed water is bit cloudy.

Is kalk water always cloudy?

In my experience, my kalkwasser is always a little cloudy. I mix 1 tsp into 1 gal RO water and stir for about 30 seconds, then let it settle for about 30 min. Then I carefully drain off the water without disturbing the stuff settled out. I add this to my ATO reservoir which adds as needed. My calcium is about 475 to 500 ppm. As far as the Part B, I usually mix 20mL into 400 mL RO water and add this drop-wise over about 30 min. If you add it in its concentrated form, it will be cloudy where it hits the tank water. That's probably not a problem, but I don't want to start precipitating the Mg or Ca. Hope this helps.

Here is a response to a pertinent question from the Kent website. I wrote "alk" on the Part B bottle and "Ca" on the Part B bottle with a sharpie so it is clear which is which.

"Do I have to always use the same amount of KENT Marine Tech CB Parts A and B or can I dose more of one than the other?

No. Although Parts A and B are ionically balanced to compliment each other when used together equally, there are times when the aquarium water chemistry does not require as much of the A as it does the B and vice versa so they can be added at differing ratios. An example would be if the calcium level was at 450 ppm but the alkalinity was only at 8 dKH. Then it would be beneficial to add the Part B without the Part A."

Thx, u mean you wrote ca on part A?(typo right lol)

Based on the rest of your post, I think you meant Ca on part A. I haven't used this product, so I'm not sure which is which.

Sorry,

Part A is Calcium and
Part B is Alk

Sorry,

Part B is Alk

Thx, ever had kalk ro water clog up pump or tubes?
