Instant cycle?
I have an established planted 55g that's been running for 2 years. It's running 2 HOB Fluva C4 filters that's rated for 70 gallons. The current stock is as follows, 6 black mollies, 9 cherry barbs, 10 bloodfin tetras and 9 albino cories.

I plan on starting another planted 55g that I want to have 15-20 serpae tetras, 8-10 peppered cories and 1 bristletoe nose pleco. Going to transfer one of the C4 filters from my established tank to the new one. Will this give me an instant cycle to where I can put my entire stock in immediately? I will plant heavy to start also to help out, also transfering a couple of the plants from older tank to help with beneficial bacteria. How should I go about this? Hopefully the filter has enough of B.B. to stock completely. I do know I would have to monitor things closely either way though.

In my opinion no it wouldn't allow you to completely stock your tank with all the fish you are wanting at once

How heavily planted are we talking about? What types of plants are you talking planting?

For the sake of discussion, lets say that the only bacteria in the tank is in the filter. So right now half the bioload is being processed by each filter. If you move one filter over, that filter will be able to process half of your current bioload, so that's the amount of fish you could add at once without initially overloading the system.

A bunch of crypts, jungle val, 2 anubias from established tank and floating wisteria.... So maybe just 10-12 serpaes then to start and then add slowly from their?

Sounds good on paper. But in reality, no. Stock lightly .

what i went with. i used half old media from my 55 in a new planted 55 close to same amount of plants as yourself. here is the thread.

Jaysee that simplifies it pretty good. Wasn't thinking of it that way.

Smit, I would think that you wouldn't have a problem adding the group of serpaes. Then watch and monitering the water. Floating plants always do best in new tanks as they are fast growers and take up ammonia faster. I would wait a couple of weeks after to add the next group of fish tho.

Cloning tanks can be a bit tricky until you get a handle on it, takes a few times doing it. As jaysee stated, the filter will instantly cycle half the current bio load. This also means you took half the nitrifying bacteria from the established tank. Here's how you can deal with both the bacterial loss in the current tank, as well as the desired stocking on the new tank.

A mature colony of nitrifying bacteria is capable of doubling every 20 hours, I use 24 hours for ease of math. With the donor tank plan on some 50% water changes every other day for about a week, and feed lightly, same goes for the newly set up tank. Triple dose both tanks with Prime to deal with any ammo or nitrite issues, and carry on after the week of water fun. I'll get in hundreds of angels on a regular basis, taking a tank from 10 to 100 without a second thought. It just requires a really mature filter, a lot of water changes and Prime. As long as the bio filtration is well established it's pretty routine, just a matter of math & water.

So even though the donor tank has 2 established filters on it I still have to worry, what about all my bacteria in sand and on plants, objects. I think my mature filter will be just fine.
