Grey Coraline?

[swervo513]

Hey,

Ive been dosing Kalk+2 for the past week and trying to grow some coralline. There seems to be some gray blotches of coralline growing on the back glass, but no purple or teal colors... What can I do to get better colors?

Grey is dead coraline.. Just give the tank time, and it will come if pars are in order..

Dosing Kalk? or Calc?

You should be dosing Calcium. Kalk is more to maintain PH and parameters during night when PH drops. I assume if your dosing KALK and not Calc then theres your problem. What are you Calc/Alk/Magnesium parameters?

alk, mag, calcium in that order to avoid precipitation.

Low alk precipitates Mag
Low Mag precipitates Calc
Low Calcium precipitates Alk.
This is IIRC. don't qoute me on this.

Which parameters in particular?

Which parameters in particular?

Randys Website goes into discussion about things relative to precipitation. Take a look, and good luck. Personally. I find when i'm not keeping Calcium and alk levels up to par I get the white/greyed coralline.

...Uh, what? Kalk is a traditional, cheap balanced supplement for Ca and Carbonate in low-to-medium-demand systems. Its use as pH maintenance is secondary.

Hi ... I was going to say that its a brand that supplements Calcium Magnesium and Alkalinity so why would I have to dose more calcium. I Measured my Calcium at 450-500 and I know I'm a bad reefer but I haven't gotten the other test kits yet. This is all so expensive I've been buying a little at a time. Even for a 12 Gallon tank!
