Moving Fish To New Tank

[richywiseman]

I currently have a 75L tank 30x12x18 housing 2 blue gouramies 4 clown loaches and 10 guppies,This is my first ever attempt at keeping tropical fish and I love it. I was given the tank from a work colleague who was cleaning out his attic, and I have been hooked ever since.
I have had this set up for 3 months and it is fully cycled, but I realised that to continue adding fish I needed a bigger tank.
I have just ordered a new tank(Juwel 350 Trigon) and this will be a feature in my living room.

I have the following question;
I would like to move the fish I have at present into their new home, the question is how quick?

I was thinking of the following,
If I use the water from my old tank, and run my established filter(Fluval 2+) in the new tank aswell as the Juwel filter could I transfer all the fish at once?
And through time the Juwel will establish and I can remove the fluval??

I am just looking forward to the fish enjoying their new home quicker, any help would be greatly appreciated.

Regards,

the bacteria that keeps your tank healthy is sessile, meaning it does not live free swimming in teh water but clings to surfaces primarily the filter media but to a lesser extent the gravle, ornaments etc.

so there's no point moving the water, it contains nothing but fishy waste. if you transfer the old filter onto the new tank and run it alongside the new filter for at least 2 weeks then you'll be fine. as the standard juwel filters can be a bit pants I'd be inclined to just leave the fluval 2 in there permanently anyway

you can literally just fill the tank up, get the heater on and the filter plugged in and working, by the time the water has heated up you can transfer your fish

Thanks for that, Im a bit concerned about the Juwel filter though???
I thought the supplied filter would be good being Juwel??

nah they're pretty rubbish tbh. We've the same tank and have removed the internal filter and binned it, run a couple of externals now, I know a hell of a lot of people who've done the same.

All depends on your stocking of course though, we have high waste fish so need heavy duty filtration, if you're gonna really understock and only have small fish then yeah it'll be fine. But if you have any messy fish or want to get a decent number in there you're probably gonna want to upgrade the filter. And if you ever want serious plant growth you'll need to upgrade the lighting too. Sometimes these package deals aren't as great as they seem.
