    Please help - I'm confused.

    6 month tank and recently added a Frogspawn, a Finger Leather and a colt.

    I have been adding Calcion as my Calcium levels started to drop down to 350. PH is 8.2, everything else is good. Ca went up to 450 and has now dropped back to 420. My plan is to add Calcion every third day and keep Ca 420.

    Alk has dropped to 6. I am confused as to what to add to increase it. I have Slaked Lime & Bicarb Soda. I dont have a Kalkwasser.

    When does one add lime and when does one add Bicarb? Or what else works?

    kalkwaser is another term for sloked lime.
    You add lime to maintain KH (also helps with calcium) and bicarb or a KH buffer to raise alkalinity. Best is to use the buffer to obtain the desired KH and then add lime to your top up. Check the KH daily and undjust the amount of lime so that KH stay stable.

    Thanks everyone. I think i've got it now. I'll add Bicarb Soda SLOWLY as per the table. Then maintain with lime.

    Spot on. But do not add your bicarb and calcium supplements at the same time, do one in the morning and the other one in the evening, or an alternate days.
