Fx6 Surprise

[fatmrak315]

well basically i have just finish work, and my partner pick me up. saying he's hurt his back and there a box in the back of the car need carrying in from his mum.
 
to my surprise lifted of the t-shirt covering it, and its a fx6. it a cheer me up present, ready for when my new 6 x 2 x 2 fish tank arrives it about 6 weeks.
 
i thought i was going to have to wait till Christmas to get one. and sit straying at a empty tank for ages. but now as soon as i get the tank, 3d background, i can move fish across. so on Wednesday my day off i am going to get this bad boy started on my current tank to start getting bacteria on it.
 
just had to share with people that would understand my excitement.

How big is your current tank? Those things are whirlpool makers in small tanks.

 

[fatmrak315]

4ft x 18in x 18in

 

[DrRob]

Nearly 14 times turnover, it'll be intense in there.

Yeah, I'd wait and just add some of your old media when you get it up and running.

Lucky you, btw! Wish someone would buy me an FX6!

are they really that good? Im looking for a filter for a 4x2x2 Malawi cichlid set up, depending on your comments I might buy one....

think you might be right to leave it till i get the new tank. well at least my birthday is less than six weeks away so i can ask for the 3d background and get the tank running after fitting it.

Running the FX6 on your ~243l 120x45x45cm will be absolutely fine, unless it contains ultra sensitive fish as regards current...
 
DrRob has made the mistake of thinking it will be ~14x turnover, because he has used the 3500lph marketing figure (without media), in the real world you will get upto ~2300lph which is ~10x turnover.
 
Further more, the intensity of that ~2300lph can be varied massively, just like on the FX5...
Using the standard double nossle output, you get the biggest potential flow when there is 90 degrees between the two outputs, anything else reduces the openings inside the nossle and will reduce flow.
You can reduce the input/output taps on the top of the cannister by a similar amount to reduce flow if your fish look stressed.
If you wanted to intensify the flow, remove the double nossle output and replace it with a standard (in UK at least) 22mm plumbing elbow.
Alternatively, use some plumping pipe (drilled to suit your needs) and a "speedfit" stopper with an elbow piece to create a custom spraybar.

Fair point.

thank you for your reply nobody of the goat, that great news i will play about with it then on Wednesday. the spray bar idea sounds great may have to get my partner to rig that up for me if i can not get the flow down enough.
