Calcium supplement

[coraladdict]

Hi Randy,

What would been the best way of increasing my calcium levels without having with the ionic imbalance between alk and ca?
My tank has 330ppm Ca and I would like to increase it to 400ppm.

Thank you for your time.

Welcome to the forum, Robert:)

If the alkalinity is where you want it, then calcium chloride is a fine way to go for a one time correction of calcium levels.

If the alkalinity is low, then a two part alkalinity and calcium supplement may be in order to raise both, and keep them there. A CaCO3/CO2 reactor or maybe even limewater would also work here, depending on the tank load and evaporation rate.

I would just like to add that I am presently dosing ca(OH)2 via a Neilson reactor.My alk is at 10.4.Do you still think I can increase Ca with calcium chloride?

Thanks
Robert

Robert how often did you refil your stirer how much did you put in and do you know wath is your evaporation rate ?

Yes, with normal to high alkalinity, calcium chloride is your best choice.
