Carbon dosing alk question

[LIreefguy]

I am new to carbon dosing (ps been working well ) and saw online that you should run lower alk if carbon dosing

Is this correct and why

Higher alk in a low nutrient environment may cause faster skeletal than tissue growth. Sometimes this manifests in paler corals or parts of the new growth that are effectively bleached.

Carbon dosing is good at lowering nitrates, if your corals dont have another source of nitrogen it could potentially cause issues. I’m not sure that this is always true though. I wouldn’t think that keeping alk at 9.5 vs. 8 in a low nutrient tank would cause such big issues...I could be wrong but this area is based on observations more than settled science.

In general when carbon dosing you should be careful to register some nitrates using a test kit.

Yes thank you. Heard people running higher alk with higher nutrients

So far my nitrates are still 8-12. So I am ok for now. Funny thing is Phosphates are now zero but I was running a little Gfo in my carbon and changing it out 1 ever 6 weeks Don’t know how much the Gfo worked since it’s only 1 cup in 550 gallons of water
