No, unless you are cycling with fish, is that your intention?

There will be next to no beneficial bacteria in the water so the tank will need to cycle just like any brand new tank.

Right, you didn't say that but that helps!

Your call then, some people say cycling with fish is cruel others swear by it, all down to personal choice at the end of the day.

Im guessing that as the other tank is quite small as well you won't be able to pinch some media from the cycled tanks filter as there wont be much of it? That would help speed up the process and cut down the amount of time the danios will be living in unsuitable water

Yeah that won't work then, another one to add to the 'reasons not to use UG' lol

Cycling with fish works, no-one disputes that, its the conditions that the fish have to live in while its cycling thats the issue. As i previously stated its a personal choice though, good luck with it. :)

What about using some of the gravel from your cycled tank to help it along? That's what I do to start a new tank, works like a charm since that and the filter is where the good bacteria are.

For the record, I also cycled with danios and golden white clouds. I kept up the water changes. I also swear by BioSpira, which has mixed reviews but has worked for me-never had any ammonia problem during cycling. I am happy to report I didn't have one fatality or disease during cycling. Still have the 4 originals in my community tank.

Use some gravel from the existing tank for the new one and add some Amquel or Prime to the water, and cycle with the Danios. Gravel will seed the tank better than BioSpira or any other other bacterial seeding product. You will have bacteria that have adapted to and thrive in your exact water parameters, plus they will be actively growing when you seed them, they won't have to wake up out of their suspended animation. Any lag they may have will be taken care of by the ammonia detoxifier.

I still say use a combo of gravel and add BioSpira. Each tank I've cycled using the gravel/BioSpira combo has literally been ammonia free overnight, and the nitrites started to rise the following day. I know BioSpira has it's lovers and haters though. The one thing I like about it is that it doesn't add chemicals" to the water like water conditioners that remove ammonia (I use a standard dechlorinator, but nothing else). When I was doing my first tank I used a similar ammonia remover. It lowered the ammonia reading, but took forever to get the cycle going properly and I kept having to add chemicals (in lioness501's case if gravel is added there shouldn't be a cycling delay). I decided to start over with that first tank using BioSpira, and the tank literally cycled from start to finish in a week's time. So anyway that is my experience and why I use a combo method of gravel (established bacteria) and BioSpira (neutralizes ammonia and starts nitrites immediately with no chemicals). I think the most important thing though if you are going to use BioSpira is to make sure you are buying it from a quality store, so you know it has been handled properly.

Let us know what you did and how it turned out!
