Coraline disappearing (1 Viewer)

The biggest change I made in my 65 gallon is that I turn the white lights almost all the way off and I have noticed that all the Coraline on the back is bleaching out and disappearing. Is that from the lack of white light?

They actually prefer dim lighting so that really should have helped grow more. I would check your Mg levels, assuming Ca and alk are at good levels already.

Coraline algae loves Mg!

Are you bubbling?

I'm loosing the coraline on my glass but not on the rocks. I read it was due to bubbling.

I agree with the other poster about growing without white light. All the books I read on this say to just use actinic until coralline algae takes off, then you introduce white light slowly.

Interesting. I have the fluval reef led 2.0 and was running both channels at same intensity for a while. Then I ramped down white a bunch to calm algea

Would first to make sure MG is OK!!! Then check for too high or low CA. I noticed whitening when CA is above 470-480, or if too low.
Check your testkits with fresh saltwater, you might find a bad kit.

Also swirl gently ALWAYS all reagents prior use, not SHAKING !!!!!! Results are bad readings ;-)
