Lace Rock

[Pipes]

Looking into my options for rock, and Rick (RWH) mentioned to me that he used Lace Rock. So I googled it and it looks a lot like reef rock. Obviously its dead rock, but, with some live rock mixed in, It should "cook" okay right?
Thanks for the information Rick.
What does everybody think? and Has anyone else had good/bad luck with it?

I was told not to use it but did, in the beginning. I found for the problems I had I get t rid of it and tank got better, could just be age, could be rock??? I had excess hair algae, cyano, just general poor water conditions. Rocks leaching? Dunno.

How much rock you looking for? I still may have some I can sell

IMHO Lace rock tends to be high in phosphate and other chemicals/fertilizers depending where its collected from. I've used it for fresh water just not sure if I would chance it with a SW setup.

Thanks guys. I saw it in ciclid tanks, and SW tanks on line, so wanted some other opinions.

The lace rock I used had already been in my freshwater Cichlid tank. I bought a few pieces of live rock to seed it.
Never had any issues with water quality. Did have some cyano early on but that disappeared once the tank matured more. The coraline algae took to the lace rock quickly. No algae issues other than a bit on the glass from time to time.

Thanks Rick. Until you mentioned it, I had never heard of it.

The issue with lace rock is its less porous than what we use as "reef rock"

There was a video on BRS that detailed the various porosity of different types of rock. Apparently, Fiji has the most surface area, followed by pukani and Tonga branch.

When using Tonga branch in the tank, you MUST load your sump with live rock or other media.

Pukani is notorious for PO4 leaching. It's recommended to cook the rocks before putting them in your system to reduce PO4
