seeding cement rock

[griffithimage]

I was aquascaping my 120g tank with DIY thorite rocks and liked the look so much that I ended up doing almost all of the tank with it. Could I put live rock in the sump and still have adaquite filtration? How long would it take for the live rock to seed the cement rock?

Thanks

I'd guess 4-6 weeks would be enough to get the cement rock going, as far as bacteria. I might also spring for some copepod, mysid, and amphipod cultures, in this case. I'd just feed very lightly with some phytoplankton or tiny bits of fish food for a while.

get a cup of sand from a running tank and put it into your main tank to seed the diy live rock. it will take like 6-8 weeks to seed diy. trust me i know.
