Using cycled Genesis Rock in soon to cycle tank

[winxp_man]

So my established 150g system has four boxes of Genesis rocks. Planning on using three in the new 300 tank.

My idea to cycle is Dr Tim’s method. 1.015 sg, 85* temp, no lights, and ammonia for bacteria food. Will the three Genesis rock boxes have any benefit in cycling the new tank faster? Or will the new salt water at 1.015 make it a useless idea until the bit tank is cycled? And turbo start 900 for bacteria.

New tank will have pre-washed sand, and new dry rock.

Eventually shutting down the 150g. But have all my fish that I’m putting in the 300g in it as of now.

Knowledge upon this subject is more than welcomed. Thank you.

Is Genesis rock a ceramic media?

Is Genesis rock a ceramic media?

Yes the Polyplab ceramic blocks.

Yes the Polyplab ceramic blocks.

Your idea to develop a population of nitrifying bacteria on the media should work. It will likely develop the capability to oxidize ammonia quickly but the capability to convert nitrite to nitrate will likely take longer. What I don’t have a sense for is whether three blocks is going to be enough.

Total blocks will be 12. Sorry I meant 3 blocks as in the cage that polyp sells for their ceramic blocks.

If you’re putting in 12 genesis blocks that have been in another system for awhile you don’t need to do an ammonia cycle. Those have tons of surface area.

Donl these things leech aluminum? Every time i have used ceramic my icps have shown off the charts aluminum

People that have used the Polyplab Genesis rocks have not. I have no issue with mine leeching anything for the past 6 months I have owned them.

My question is if the new salt water, new dry rocks about 250 lbs of it, and 300 lbs of sand will cause cycling issuing with seeded Genesis blocks.

I guess worst case scenario the tank goes into a mini cycle?

I guess I will just get them in and dump some turbo start 900 an let it go from there. Maybe some Dr Tim’s ammonia to get the bacteria that is on the blocks fed.

I don’t see how combining new salt water, sand, and dry rock would affect the population of nitrifying bacteria that you established on the media.

Don’t know what you mean by mini-cycle though. If you are referring to a temporary increase in ammonia, that could mean the established nitrifying bacteria population on the media was not large enough to handle the ammonia generated by the fish.

Yes.
