Any one out there ever try adding non-live rock to an established FOWLR (fish with live rock only) tank? Is there any negative effect with adding non-live rock to an establish tank? Any suggestion? Thanks

I mean base rock (non-live). So i guess it is contaminants free.Deanos said:Just be sure to thoroughly rinse off any dust that has accumulated on the non-LR; it might contain contaminants. Otherwise, there shouldn't be any negative affects.
Damn, the kid probably had too much soda. Hope he didn't peep in FT's tank...lolzcali_reef said:I would rinse them good, soak in used tank water for a few weeks and test the water to make sure it is not leaching stuff out. I saw some kid pouring soda over dry rocks at FT few years ago, always makes me leery about putting stuff not sealed in my tank.
I think it's probably figi base rock, i'm just a little concern with the fishes in the tank.hermangareis said:The type of rock you add is also a factor. Make sure its safe.
Yea I would probably do the same thing, check for ammonia as well.Alfredo De La Fe said:Make sure that the baserock does not have any organic stuff in it that will start to decompose when put into the tank. At one point it was alive, which is reason enough to be concerned.
I would put it in saltwater for a few days with a powerhead. Do the "sniff" test and check the nitrates... If all is OK, it will not be a problem.
