Setting up a new tank from an old one

[apastuszak]

The obvious answer to me seems yes, but I figure I would ask anyway.

I have a 55 gallon tank with a Fluval 304 on it right now.

I have a 44 pentagon I need to set up and I have an aquaclear 300 on it. If I hang the Aquaclear on the 55 gallon for a month, and then fill half the 44 with water from the 55 (and obviously top off both tanks), I shouldn't need to cycle the tank, should I?

Do I need to wait a month, or will the Aquaclear seed with enough bacteria sooner than that?

A couple weeks would probably do the trick.

You can skip the old water if you want. There isnt much beneficial bacteria in the water column

Sweet! I'll have the second tank up by Christmas!

I just swapped my 75g to a 90g with a 40g sump.

All I used were a few sponge filters which were in the parent tank for about a month.

New substrate, new filters (sump) everything new.

Transition went well. I acclimated the fish, no deaths, no bacterial bloom, no signs of stress.

The 90g only ran about an hour to get the temp stable before I made the switch

You'll definitely be OK. Take your time and acclimate the fish correctly.

Sponge filters are also fantastic for this. I have 3 running that are all ready to be easily moved; no hassle whatsoever

Anyone else notice the aquaclear seems to take longer to seed then other filters? Mine seem to at least and the quickest I have seen was a whisper30 cheapo lol

If you can get a bottle of instant biological bacteria = instant setup for any tanks!

True, but I personally feel more comfortable with the traditional methods when given the choice

Setup many tanks using only some seeded filter media and/or substrate from a seasoned tank.

No problems so far, just keep an eye on the levels and don't stock too heavy or add new stock to the existing right away.
