baking soda recipes to raise dkh

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.

i am using rowalith C+ and maintaining my CR at ph 6.35 best for rowalith C+. so far it the the best i can get and stablize my ca 400 and dkh 7-8. so, since eveything is stabilize, i though it is time for me to raise my mg a little to the desire level and maintain it there using zeomag. say 1350ppm.

my salinity is maintain at 34ppt.

This is problem using Rowalith C+ and that's why I am using ARM instead which includes trace elements too.

hahaha... ARM is expensitive lah... i need <10kg to fill up my CR...

Not expensive if you know the source as the damage for 2 x 8lb bottles was less than S$90.

Hi Loster,

I had the same problem as you on KH, but look at my parameters and u will realised it is different.

CA = 600ppm
MG = 1500ppm
KH = 6dkh
PH = 8.0

CA & MG used TM to measure
KH used Sera to measure
PH used Aquaz

tried Baking soda for 2 days and still no changed in KH.

I used Coralife salt, I think that's why my CA & MG are so high, if you want to boost ur MG, Coralife salt may solved your problem.

Anyone can help me?
