Carbo-Calcium Powder Calcium & Alkalinity Additive - Tropic Marin

[jetskiwilly]

30 gallon tank....I've calculated my Alk consumption at 0.5 Dkh per day.

From website....https://www.bulkreefsupply.com/carbo-calcium-powder-calcium-alkalinity-additive-tropic-marin.html
Tropic Marin Carbo-Calcium Powder Contains: (per 700g)

• 40,000 mg Calcium
• 5,600 dKH

Does this mean that $21 dollar bottle will last me 11,200 days??? 5600 dkh / 0.5 dkh per day = 11,000 days. Something is extremely flawed in my calculation...what Im I doing wrong?


Following dosing directions -----Starting with a daily dose of 5 ml of Carbo-Calcium liquid solution per 100 liters (26 gallons) of total system volume. Increase the daily dose by monitoring the alkalinity. Increase the dose by 2.5 ml per 100 liters until a constant alkalinity of 7-9 dKH is achieved. Fl

Lets assume I end up using 20mL per day (I dose 480 ml in Kalkwasser per day) ---- 5000 ml / 20 ml = 250 days.



Do I want to use this method? I dose Kalkwasser and have to had ALK to maintain. more softy than SPS. If I use this Tropic Marin Carbo-Calcium I can see me being required to dose additional things to maintain....not only ALK, but trace. Which has me leaning to using EVS B Ionic

Nope.

the write up suffers some translation issues. Powders never contain any specific dKH, only solutions do.

But if the tank is 300 L volume and you add 1 L of fluid that contains 5600 dKH, the boost is 5600 dKH x 1 L /300 L = 19 dKH.

Thus, if you needed 0.5 dKH, that 1 L would last for 38 doses.
