What do you use to dose ALK, CA (& MG)

[L/B Block]

So after a thread from @TwinsReef about dosing-I am curious to what people are using for their tanks for CA/ALK/MG

I think I got the mainstream mechanisms but if I am omitting something I’ll append accordingly.

 

[IOnceWasLegend]

Calcium reactor for my 200g display, two-part for my coral QT tank.

 

[Patio]

Kalk for alk/cal

weekly water change for mag. Test mag maybe once or twice a year ish.

 

[richiev]

Main tank is 2-part, but will add Kalk soon. Frag tank is Kalk + AFR.

Also dose AB+ and phyto, but that's not what you're asking about.

 

[tankguy]

I use Aquavitro 8.4 for alk

 

[divewsharks]

I dose KALK + AFR on 150G display.
Just AFR on 40G

 

[Turkeysammich]

1.5 gal water change a day, Kalk stir( Mississippi pickling lime )to evap water. alk ( baking soda), cal (Brs), on dos. To make up any difference. Mag (Randy’s recipe products from Amazon) by hand if needed.

I use 2 part in my DT. Then my coral QT gets AWC from DT in hopes of keeping the chemistry the same & making maintenance less of a hassle

 

[grizfyrfyter]

I use kalkwasser/alk/MG

I would absolutely use a calcium reactor and kalk. That was without a doubt, the best coral growth I have ever had. I just can't afford it.

@divewsharks & @richiev -for your tanks with AFR & kalk-
Assume AFR day and kalk night-curious to know your ph range (high/low/average). Thanks

Depends, but around 8.1-8.3 currently. When I suck at keeping the Kalk consistent it moves. Without Kalk that tank drops at night below 7.9

Thanks for sharing. Useful info.

While I do dose more KALK at night (KALK Stirrer), KALk does dose through out the day with AFR supplementing.
Very slow drip at diff times a day using a Ecotech Versa.
With the stirrer, I need to add couple tablespoons of KALK powder each week to keep max potency.
My ALK peaks around 8.3ish, when the peak doesn’t reach there, I know I need more KALK powder stirrer.

Thanks for the info as well. Very helpful.

I dose 2 part that I make myself using “Randy’s Recipe.” It’s super easy and cheap.
