does kalk boost Ph

[chip]

Been dosing kalk for over 3 months. Coraline growth is blooming however my ph is 8.1 and even my alk is very low 8.6. I kalk dose 247 and make a new batch every six days. The ph out of the kalk is 12.0 however my tank seems to be very low. Any input would help.

Yes, limewater will raise pH. How much lime are you adding to how much water, and how much of that are you adding to your tank?

Most tanks using limewater run above pH = 8.2, and many run above 8.4.

Also, if you add buffer to get the tank at 3.5-4.0 meq/L then your pH should stabilize at around 8.4, and the kalkwasser will maintain the alkalinity for the most part.

What kind of lighting do you have? What is the photoperiod? How much circulation? Do you have a skimmer? If so, what kind? Do you have a refugium? If so, what is the photoperiod of your refugium and what kind of lighting do you use on it?

My actincs are on for ten hours then my 250 watt halide comes on for five hours. Now thinking of increasing photo period, however will that Ph very much? Been adding about five big teaspoons to five galloons of di water every six days. My tank is sixty galloons and am using a tunze 210 skimmer. The skimmer works well and pulls alot out so that is stops skimming at times. This without putting hands in tank. No refugim.

Increasing the photoperiod on your MHs will probably increase pH. Mine hovers between 8.4 and 8.6.
