Live rock colour variations within a reef tank

[Skimmerking]

alot of times that the 6500K and 10k can actually bleach out your rock and the coraline too . I ran into the same problem but doing water changes isnt actually going to bring your coraline back to life.. well may be the cal and alk will keep up but itws the PH that is being stable is causing your coraline to grow.
if you notice that flouresant bulbs are the best for growing coraline algae. like VHO's or Normal flouresants.

but be careful what you wish for kido. Once the coraline starts growing its going to start consuming yuour CAL and ALK. trust me my stank can easy suck up the CAL and ALk in my SPS tank if I ckeep the coraline off the sides it slows it down so much that my Kalk reactor can handle it /

I was suggesting water changes to help keep the calcium and alkalinity at a decent level which should help the coralline growth.

Mindy i wasnt saying that you were wrong im just stating that proper PH levels will keep the coraline at a normal rate.
but yes cal and alk has a huge part in there too. may be i just worded it wrong sorry about that .

I was clarifying what I meant for the OP, I wasn't sure I was clear when you made that comment after. You're right though, a low pH does tend to limit coralline.
