Woo-hoo Tank Upgrade!

[Harlequins]

Hi all

i have just bought a newish second hand tank,very good condition,dimensions 120cm x 40w x 45h,according to the calculator its 48 imp gals (216 l), it had 2 heaters,various foods,bottles of tank cleaner etc,2 books of fishes,timers,large magnet cleaner,no filter unfortunately,but i am waiting for an external to come,i planned to put it on my 20 gal
All for £90!!

Do you think the tetratec ex 700 canister will be adequate for this tank?

Also there is a backing inside the tank that has been stuck on with silicone,looks rough in appearance,do you think this could be removed or best leave it?

here's a pic what the tank and stand looks like,although the dimensions are not the same.

I'm just undecided whether to cycle it from scratch or put the media from the 2 filters from my 20 gal straight into the canister when it comes,but that means transferring all the fish across also!has i haven't got the room to keep the 20 gal as well,which is a shame!

If i did clone using the filter media straight into the new external,and move the fish across would i get a mini cycle?
I don't intend to add addition fish just yet.

Sorry for all the questions,but i hope you can help

Last night i partly filled the tank to make sure there was no leaks,the backing had become wet and stank to high heaven this morning,on closer inspection i noticed the backing was covered in algae.

so i decided to remove the backing and spent 2 hours scrapping the silicone off the tank,

Anyway thats done,still waiting for the filter to come.

If it was a structured background I'd have taken it off anyways. That's valuable fish space that it's filling!

Congrats on the new tank.

If it were mean and there was enough room in the new canister for the mature filter media then I would shove it all in there (with all of the fish) for at least 4 weeks to seed the new filter. Then if you want the other tanks back up n running remove the old media and pop it back into the filters it came out of.
You may experience a mini cycle, but I doubt it.
