baking soda recipes to raise dkh

let me know if i am right or wrong for this calculation

1 teaspoon (>6gram) of baking soda raise 1dkh in 50G of salt water

therefore: 4 teaspoons of baking soda raise 2dkh in 100G of salt water

why u want to use baking soda to raise alkalinity, there is product to raise your dkh. If i'm not wrong baking soda will make pH in higher scale so do be careful on the dosing.

actually no matter how much i use those product, i only can rise my dkh a little. so i read some materials from RC and studied a lot of water cheminstry. so, the only cheaper way to raise dkh is to use the baking soda...don't worry, i aware of the ph...

Bro,
How is your PH?Does it fluatuates daily?
Is your Mg ok?

Regards

i am working on my Mg. that's why i need to raise my dkh to 10 than i will have to further increase my mg to the desire level. i am using CR and i always have problem with my dkh till i measure my mg.

actually i dare not increase my bubble count for my CR (low ph) and i have been pushing my CR too hard.

I think you should raise and stablise your MG to the desire value before you do anything to your dkh.

I am maintaining around pH 6.6 inside the reactor using ARM and is getting good results in terms of stable kH & pH.

What is your pH level in the reactor?

Are you using ARM?

You may wish to note that if the salinity is less than 35ppt or a deficiency in magnesium will cause difficulties in acheiving the right calcium and alkalinity levels.

If the calcium level needs boosting, then I recommend using an additive such as calcium chloride. One gram of an anhydrous calcium chloride product (such as Turbo Calcium) will raise the calcium level by 360 ppm in 1 litre of water (95 ppm in 1 gallon of water).

If the alkalinity level needs boosting, then sodium bicarbonate can be used. One gram will raise the alkalinity by 12 mEq/L (34 dKH) in 1 litre of water (3.2 mEq/L (9 dKH) in 1 gallon of water).

In both cases, I recommend making changes slowly, rather than adding them all at once and contact Bro Sandman (Ken) as he had done a bulk order for these additives recently.

Agreed that you solve the Mg issue before taking another step as low levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper calcium levels.

Also, magnesium depletion is commonly associated with the use of kalkwasser.

Theoretically... you are correct

ya... i have been using kalkwasser since day one. now stop for time being. actually my dkh and ca have been stabilize since i managed to raise my mg from 900 to 1200 over few weeks. after some time, when everything is stable, i tried again to raise the mg to the desire level (1350) but i can't even though i used ken's mg chloride.

since i have put the zeomag (10% of my CR vol) into my CR, i will just let the CR maintain my Mg. i will see what else i can do next

actually without lime water (use as a top up), my ph drop to 7.9 when light off. may be i got to off my c02 at night
