Supplements for live rock?

[haywood2]

Is there a good recommended live rock supplement that I can buy online? I've heard that the rock may need supplementation so I figured I would ask here to see what you all would recommend. Thanks.

Not that i've heard of.

Ive heard of purple up, it just helps coraline growth. Dont know if it actually works or not though. Most "suppliments" are garbage.

I would say time is the best way to go. Patience.

I would not use any supplements, just give the rock some light and things should start to grow nicely.

I agree, beyond keeping your Ca between 380-450, and your alk between 7-11 dKH and enough light, nothing should be required for coralline algae growth. Purple-up is basically just powdered sand and does not have any special connection to growing coralline algae or making rocks purple. It is just a way to add calcium and carbonate at the same time. Kalkwasser or a 2-part supplement is a much better way to grow coralline algae IMO.

How do you keep the calcium levels up, water changes?

Yes, the water changes will keep the calcium levels up.
