    Raissing Calcium 120ppm

    My calcium is low cause i was out of town for a couple weeks and no calcium was added so i wanna know if theres a safe way of raissing it and how fast can i raise it without damaging anything. Its now at 300ppm and i wanna bring it to at least 420ppm. I use Tropic Marin bio-cal

    I don't use Tropic Marin Biocal calcium so I can't help there but, I'd keep an eye on your dkh too. An easy way to get things back on track is to do a big water change. If you're staying on the Ca route than I never raise the Ca lvls by more than 40(ish)ppm/day and even that's pushing it for me. If things are really messed, ca ph and alk, I'd do the big water change and fine tune it from there.

    Here is a cute little program from Seachem specifically to raise/adjust water parrameters.I dont use the Bio Cal but if the amounts to be added are simular to Seachem it may be good.
