Meshwheel friggin rocks on Gen-X 4100!!!!!

[Josh125]

Ok - I modded my Sedra 3500 and went from 3M to P4 mesh. The results, ehhh so so. I'll give it a few days to break in but I can't honestly see much of a change in skimmate.

I was only able to fit 2 layers on and the pump had a bit of a time getting going so I think 3 is out of the question.

Mavgi thank you.

I got 6 lpm increase in air flow after mod the sd9000 with 3 layers of PF4 mesh. Not bad at all. Here are the pics.

Nice!
I need one of those meters... but it seems like my skimmer is better than before, so no need at the moment.

 

[kentrob11]

Was that in a bucket or on the skimmer itself? How many feet of head if on the skimmer?

 

[wayne_sreef]

I test both while in the bucket and on the skimmer. The reading are the same. The skimmer is ASM G4X so it is about 30" tall.

Hey, guys
Has anyone tryed to pump air to a mesh wheel? My favorite skimmer is 7' tall (Actual head pressure of 60" )and i want to see if i can get 40- 60 scfh of small bubbles to it.
Before i buy a $140 air pump just want to no if anyone has had any sucsess or failure?

is anyone getting dark skimate with the mesh? since doing the mod all im getting is lemonade

you skim wet

you need to reduce more the water level and you will get this :

mavgi -

Without shafts, what do you do if the power goes out and you are not there to spin the impellers by hand when it comes back on?

it will not skim till i come , but sometime not need to spin the pump . you can pick up the pump of water and it will spin.

on the sicci pum it will not spin just with finger .


Malifluous:

look on the picture :

it's look nice but i get the same result on the sedra 5000 when i increase the air intake hole . i believe you can come near 20LPM if you will do it on the sedra 9000 . it's a stronger pump and the air intake can't pull more because the hole size.
if you happy with what yo got you can leave it as is, you run 2 pump on your skimmer and mod both if you will increase the hole on the 2 pump you going to get total of 37-38 LPM or 80SCHF .
the true is i don't know if the skimmer body will handle it

Meshy and good.

it's take little time to get use it but aftter a while it's rock .

you can see on kent post : "Just measured the air on all three pumps and I'm getting 16 LPM, 17 LPM and 18 LPM. I'm not sure what the difference between them"

if you find the correct way to do it you get the max air . more then that after the pump work more day or 2 the 18LPM will be 20LPM.

this is the MESH

Mavgi- Is that pic you posted of the meshwheel off the bubblemaster pump? It didn't look like there were any zip ties on it....could you take some better pics of how the mesh is mounted to the disc?

yes , but if you want to mount like that you need to work more

Is that a little thicker than the stuff I got from you or is there just more layers of it on that impeller? If so, How many layers of it do you thinkthere are on that one? What is the diameter of the mesh wheel?

to much question:lol: :lol: :lol:

first there is good and bad on that mesh i try it

it's more thicker , it will not match to all the pump , and to expensive (1 like this build can cost more then $50) and it's going to make the mod not so lovely, ppl that cant put more then 2 layer will not be able to use it and if you ask me 3 layer are better.

if you can put wider you will be able to pull more air but not all the pump have space to put wider diameter .

the performance with this type wasn't so good and because of that the pump changed.....

i forgot the good : was easy to mounted:lol:

With a denser pile it would clog easier as well. I'm actually going to cut down a 400 GPH pump and mount a much larger volute housing on it with 1" in and 3/4" out and install a large (3") meshwheel on it....

can you show exactly or draw whay you want to do ?

3" mesh on what pump you want to put

My turn

My turn

I'm still too scared to destroy a $100 impeller for my Euro-Reef 12-2 quite yet. Even for registered owners, that's $75 each, and I have TWO! So I grabbed my back up ASM G-3 since it uses a Sedra 5000 pump as well. It's been acting up, and I wanted to know what the problem was. After opening it up, I found the ceramic shaft was broken and the magnet has a huge bulge on one side. That can't be good.

So I dipped into my backup bin of goodies and pulled out another Euro-Reef impeller and ceramic shaft, and got to work. Here's the impeller and the mesh.

I cut out a few squares of the material for the layers.

I cut off the pins with a utility knife, leaving two nubs at 12 and 6 o'oclock. It may not make a difference, but I thought it might help keep the mesh in place when it starts up (against the torque). Next I trimmed off the edges, leaving some excess but had to trim it again so it wouldn't drag against the inside of the impeller housing.

Then I tested it. I grabbed a bucket, 2g of warm tap water, 2 cups of salt, and a modded pump.

There was a faint Niagra Falls like mist emitting from the from the bucket.

Good enough for me. I put it in my LR-cooking barrel, which has had the same 20g of water for the past month. It has a single pump, salinity at 1.025sg and about 55g of LR that is shedding any remaining detritus / algae.

One minute:

 

[melev]

Again at 3 minutes.

And at 15 minutes.

I'm now waiting to see what occurs...

I didn't test for wattage before, but my other Sedra 5000 uses 40w of power. I don't have a air meter yet.
