View Full Version : making cement rock live

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?

yes and i started seeing coraline in 2-3 months and complete coverage after 6. just scrape coraline off the glass of an established tank and sprinkle it on your rocks in the tank then keep your glass clean and it looks alive soon enough. make sure its cured of its high ph and then just go for it

is there a minimum amount of live rock needed to filter 120 gallons?
