| Filter Flow Diffusers
First of all I swear that all the crust looking white areas are NOT on the tank or filters!!!! OMG....going to throw the camera away!!...but here is some easy help. I am using 12 inch clear plastic mailing tubes and cut for desired fit and looks.
1.) They are 2 inches in diameter.
2.) I leave both ends open with some course filter media inserted.
3.) Mailing tubes come with caps so you could have the current directional.
4.) For the HOT Magnum type filter only a hole is cut to fit the L shaped return. The diffuser is just slipped on the tube. (they are very light weight.)
5.) For the Aquaclear type filter A.) a slot must be cut. 3 sides...2 narrow and a long cut the width of the filter return. B.) the 4th side of the slot must be folded to slide up under the filter return. C.) a nick can be cut into each end of the tube and a large rubbr band will attach it to the filter. (my photo shows the prototype...using duct tape!!...been running 8 months now so why fix it)
6.) I did this so the water flow does not swish my plants around. The 2" diameter give a much broader gentle output and DOES NOT AFFECT the input flow of your filters....they can continue to run at max.
Again so sorry for the scrungy, scaley, unkept neglected look in the pics...the flash was too bright i guess.
Oh yea, and please use the filter media of some sort....fish the like currents might invade the tubes!!!

| I didn't have any of the mailing tubes, so I used a small soda pop bottle.
So far I've done it on one of my betta tanks, works great !!!
I left it open at both ends, but it diffuses the water really well. Now that he is'nt getting blown around, he seems to like hanging around the front of the tank alot more.
Later on today, I will do my other two tanks.
Many thanks for this great idea.........

| I just did my 29 gal,
With the water diffused out to the sides, I was able to use tall plants to hide all the plumbing.
So cool.............. 
Thanks again,

| If you don't have filter floss, can you just cut a chunk out of a filter cartridge? | |

Very clever idea. never considered haveing a filter diffuser. but can clearly see the benefits. such as hiding the plumbing I'm always trying to hide that stuff but filter current makes it almost in possible. Think I have a new project.

| Hello Martin,
Defusing the filter flow works well when the filter may be too strong and the fish are being blown around the tank by the filter current.

| ok that makes sence, but does litlery nothing to the filtration process, other then allow O2 in the diffuser | |

| So essentially this is attaching a tube or bottle to the end of the outlet pipe that is stuffed with filter floss/sponge, to lessen a strong current? That's great. I'm going to have to do something like this. I turned down the taps on 2 canisters, but I'd rather another option. This might well be it! | |
