too much media in a FX5?

[Morledzep]

the water is visibly moving in that tank.. i don't see a problem with your flow. just the same i would stick with the fluval bio rings and get rid of the eheim stuff.

only time i've heard of FX5's being slow is when the polishing pads plug up. and they do, i like the cut to fit blue or white filter material rather than fluval's FX5 polishing pads. i also have some filter material sheets that are impregnated with carbon that i use occasionally..

i run the foem blocks polishing pads blue and white pads filter floss carbon and aome amonia rem.

i think what you're looking for is for things to blow wildly past the outlet.. you have to remember that the outlet pipe on that is 1" ID, it's much larger than the pipes on smaller canister filters. so you don't see as water movement as you're used to seeing.

the same goes for the suction side, there is plenty of water being moved, but there isn't a vortex of water sucking everything in the tank into the tube because the tube is larger and that reduces the visual effect of the water in motion.

remove the eheim gravel stuff.. it's not necessary, and 2 baskets of the fluval bio rings have more than enough surface area to hold all the bio material you'll ever need, no matter how big the tank is or how many fish you have in it.

i run my 150 gallon tank with 2 foam filters (run off an air pump) and a fluval 405 with fluval bio rings in only 2 baskets. that's less than 1/3 of the bio rings you already have.

BUT what about the flow of the outtake is that ok in the video? im going to load another video of it here in a minute

Its hard to tell in that video. The reason is, I have only notice how good the flow is while the output is above the water level so I can see how far the water is shooting out of the nozzel. I think your flow is good, but I can't be sure. Remember, the output flow is split in 2 with that output nozzle.

You can do something like this, which will give you more flow in one direction. This was the best thing I did to mine to get more circulation.

In my 55 Gallon, the flow was actually a bit to much I think, so I turned the filter down to about 60%. I recently converted to vinyl tubing and my output is a bit larger in diameter so the flow velocity is a bit less which means I can crank up the Fx5 to max without blowing my fish around.



What many do, any this would help, if you want to do this, remove the cover from the aquarium, disconnect the hose from the output nozzel and take a video of how far its shooting out from the hose. This will help better.

I think I have a video of mine, I'll see if I can dig it up.

Its not because of the size of the tubing, in some cases it is, i'll get to that later.
The Fx5 has a continuously tested 600 GPH flow rate. The output nozzle splits the flow into two so the flow velocity gets cut in half.

Now if he took a canister which has a 300 GPH flow rate. Used 1/2" tubing from the canister to the tank, and noticed the flow velocity, then switched to 1" tubing with the same flow rate, you are correct, the flow velocity would decrease and he would not notice it as much.

the same goes for the suction side, there is plenty of water being moved, but there isn't a vortex of water sucking everything in the tank into the tube because the tube is larger and that reduces the visual effect of the water in motion.

The reason the intake doesn't seem to have much "suck" to it, is due to the design of the intake strainer. Its very large with a lot of the basket open. If you plug up some of the slots, you will notice there is more suction in the open areas than before. Doesn't have much to do with the tubing.

Now if you took a canister with 300 gph flow rate that has 1/2" tubing and 1/2" intake strainer, and changed it to 1" tubing with a 1" intake strainer, you would have less suction at the same flow rate. Now its hard to say "1inch" intake strainer or "1/2inch" intake strainer because its really the design of the strainer its self and not the initial input size of the tubing.

On all my Fx5's i have removed all the Multi-directional output nozzles!Replaced the ribbed hoseing with Eheim hoseing and they are all filled with only Biomax.Every one of my Fx5's are BLASTING!! ive NEVER experienced ANYPROBLEMS with any of my Fx5's.

 

[puntoturbo]

O yea! I also made sure i cut the hoseing as SHORT AS POSSIBLE! All these little mod's HELP alot in producing maximum FLOW!

You can use standard 1" ID Vinyl tubing. Don't need to use Eheim tubing. More money for a name

I know mate! lol i just like the colour of Eheim hoseing(GREEN) blends in with my tank's BACK GROUND! All my setups backgrounds are painted Amazon Green,so the Eheim hoseing goes well within them.
