ah i love the fx5 coz its self priming, fill it up with 8l of dechlorinated water or tank water, push the valves back on, and switch it on. if its not been cleaned out just switched off and left while the water change was done, just plug it back in and off it goes, runs for 2 mins, turns off, purges itself of any air and starts up again 
bet you cant wait to get those big beautiful fish into a pond hey, can understand why they may be going a wee bit nuts in a 200l
bless em, at least they are well cared for and its not permanent 
we were at the pet shop last night, and there was a woman there stocking her 25l tank. she chose 2 common goldfish and a comet goldfish and would have kept chosing had the assistant said 3 was enough...for another 2 weeks
i was having a mini-rant at hubby and the manager came up to us to ask us if we were ok, i said yes im just a bit annoyed at people who dont know any better. he said whats wrong, so we told him what they were doing, and he agreed it was wrong, but said its company policy that no matter what size the tank is, that they can sell to any filtered tank 

he even said he hates doing it and started talking about how big their tank was, it was 18 inches long, and even though they heard us talking about goldfish growing to 18 inches, they carried on regardless! naughty as i am, i came away with a stunning 4 inch common white and red goldfish, it was just too pretty to leave there to a possibly awful slow death on someones tiny so called tank
splashing out on goldfish at £2.99
good job im massively over filtered hey
