Help Me With My Chemistry

[truthdesigns]

My tank Is a 60 gallon cube mixed reef
mostly SPS. I have a 20 gallon Fuge with macro
a ASM G1x Skimmer and I recently added a ATO
I am dosing kalkwasser threw my ATO and I am adding
no other supplements. Here are my Params please help me!

Ca: 420ppm
Alk: 6 DkH
PH: 8.0
Mg: 1200
Temp: 81.3
SG: 1.026
PHOS: ?

with low dkh and ph increase the kalswasser dosing--both should rise.
aim for alk at 10dkH and pH 8..2-8.4

I would use this calculator to figure out what/how much to dose to increase mg by about 100 and alk by 3-4dKH.

How are you making and delivering the limewater?

 

[truthdesigns]

I mix the kalkwasser In a 2 gallon Jug. I add the ROM/ADI
To the jug then I add the kalkwasser. I then mix it with a wood spoon and leave overnight. I then add the jug to my top off container which is a 3 gallon jug. I try to not let the 3 gallon go
completely empty. I am going to find a bigger container for my top off maybe a 15 gallon, Is this OK?
Thanks For the response!

Saturation for lime is about 2 tsp per gallon. How much is being added?

For the moment, I'd dose the alkalinity up to at least 7-8 dKH with some baking soda dissolved in RO/DI water.

 

[truthdesigns]

hmmmm I am dosing 1 tsp per gallon.
How much should I dose baking soda?
Baked Baking soda or just baking soda?

 

[Randy Holmes-Farley]

I personally would just up the lime in the limewater to 2 tsp per gallon of fresh water and see what that does over a few days, and not yet get into dosing anything else. But if you want to immediately boost the alkalinity to 7 or 8 dKH (or more) with baking soda, that too is fine, then see if the increased limewater can keep it there.

Sweet Thanks Randy Holmes-Farley
I was told you can solve my problems here!
Also thanks to everyone else who helped out!!!!
I will see what happens in the next few days.

Plain baking soda is fine, and the calculator will help with a dose:

You'll need to guess as to the actual water volume of the system.
