my kh was low, around 6-7. to me coraline will grow quickly if water if stable
I dose this and my coraline goes crazy.

I even have 5 urchins that devour the stuff, as I think so much coraline is smothering my LR. They are doing a great job, but I think I need another 5 urchins.

I wish i have this problem LOL

I was afraid of that... I'm not sure it could very well be copper.

I did get growth on my corals though, some of them are growing like crazy so could it not be copper?

If it's not copper but some other medication than is it ok?

Thx

That might have something to do with it, particularly as lockrookie said... if it was medicated with copper (I too would not use the rocks in a reef tank if this were the case). There are a multitude of factors that may be contributing to your decreased coralline growth. It is likely a combination of things. Your low dKh would likely be contributing as well.

As for Purple Up... I am under the impression that Brightwell Aquatics Elemental product is the same, so if you are not able to get one then try looking for the other. You will still need to maintain Ca, dKh, Mg lighting and flow, but using Purple Up or Elemental (will increase your Ca and dKh simultaneously but not proportionally) have been reported to promote coralline growth more than standalone Ca and dKh supplements, although you will likely still need to dose the individual components for fine tuning.

One other thing to note... although both of these products report to contain other elements (Mg, Sr etc.) they are in such low concentrations I would treat them as if they were not present.

That's my thought on it as well. If it builds up too much on the rock, it blocks all the pores we paid money for. This is where the denitrification takes place, so covering it isn't a great idea.

My dKh is good and stable, it is not low. I'm getting growth on my corals, so do you think it is not copper? if it was another medication that was used, would it be ok?

That makes sense lol, i guess there is a up-side and a down-side

I had the same thing in my tank when it was about 4-5 months old.

Purple Up won't really work unless you had a bit of Coralline to begin with.

You need to "seed" the tank with a bit of Coralline to get it going. Try getting a shaving of Coralline from another tank or even your LFS, then chop it up into as small as you can get it and drop it into a high flow area of your tank. This will spread the Coralline throughout your tank, if you have sufficient Calc, Alk, Mag it will grow.
