lighting and coralinealgae

[AnotherGoldenTeapot]

You do not need MH to grow coraline.

You do need clean water with very low phosphate.

Maintaining the alkalinity at higher (twice is more than enough) than NSW levels leads to very fast coraline growth. I asumme you're happy to do this given your current calcium level

.

You say you have *some* coralline already - this will eventually seed the tank if the conditions are right. Growing coralline gets white spots on it, and / or a white rim around the edge. Once yours looks like it is growing it will take a month or so before you notice coralline growing in other places. This starts as spots almost too small to see, which grow very quickly.

A calcium reactor is the sure-fire way to get coralline to explode. These are not cheap though.

i have 58G reef tang with Hammer, Torch, Frog Spawn, Cup,Leather,etc. the tank is 2 years old, running 4x30w florescent(total of 120w). All corals look good and grown, except Leather (up and down day by day). Water testing is fine. i just raise calcium up to 600 ppm. i thought i will help to create pink coraline algae on rock. the rock in the tank just have very little pink color. i am not happy with that.
I have some questions. Please give me some advise
How to create pink coraline algae on the rock?
How is my lighting? if upfrade to MH, please give me specific watts, brands, and retailers, and how hight should MH stay (My room temp. is 78 degree). I currently have DIY canopy. Thank you and Happy Thanksgiving.

I would add metal halides or VHOs. They would support your livestock better. The leather may be too close to one of your LPS corals. It may be getting stung by sweeper tenticles. Or their is an all out war going on,chemically,between the two and you just cannot see it.

As far as MH or VHO retailers you can search any of reefs.org's sponsors. They all carry quality products at good prices.
