Anyone Modded a Weipro into a needlewheel?

[ervine]

Woah... skimmate looks very thick.. what pump u using bro...

also, i noticed u have the water level pretty low huh.... tot most weipro users raise the water level all the way to the neck level?

How long before ur skimmer broke in btw?

[rockfish]

i thik it only that overnite .. maybe about 12hr ... not too sure ... i just set it up .. then next day got skimate liao...

the skimate is very thick becoz of the mircobubbles ..

if put the water level all the way up to the neck .. the skimate is very dilute and have to pour very often ... waste my salt water too ..

the main point is to put ur pump near to the water surface .. in that case .. more airbubbles ..

oh yah .. i did not mod my pump at all .. and its a "no brand" pump running at 1200 L/hr .. and my outlet is fully open.

[ervine]

Hmm... okay I try to see what I can do with mine... hope to see kopi-o soon too..

hi people, just got a 2011 weipro. interested in how you make the 'needle wheel'. what do u mean stuff air tube in? into where?

is the airtube connected to airpump?

[rockfish]

i just stuff the the air tube into the lnlet of the pump .. i think by looking at my pic .. its quite obvious ... i din do anything to my pump ... just add air tube ..

[FelixSu]

cool !

could we have a picture of your pump inlet pleaseeee?

hmm... that's a veri simple concept

[ervine]

AHhhh.. I managed to solve my problem (well sort of)

I noticed that I had was either of these 2 problems that caused the skimmer to behave like it did..

1. Not enough air being sucked through the venturi

2. Too high water flow compared to too little air

So taking "inspiration" from bro rockfish, I shoved another air tubing to the inlet of the pump... that did 1 major thing, it slowed down the water flow and allowed for most of the bubbles created to reach the surface of the skimmer before getting sucked out into the output..

6hrs into the mod I already have foam forming and my first few drops of skimmate!!

Will post pics on progress soon...

[rockfish]

Yeah bro!! way to go !!

glad u solve the problem .. til then ... happy skimming ..

[ervine]

Not good enough yet leh.. the bubble size quite big still and not a lot of bubbles actually.. think I try to get a maxijet 1200 and fit it with my needle wheel will be better.... will keep updated...

*DEEP SIGH*

After several days of trying to tweak the skimmer into a pinwheel driven one I've given up... somehow the venturi is creating higher bubble density than the pinwheel... Maybe it's the way I made the venturi intake or something.. shrug..

Oh well.. never try, never know...

[Oceandeep]

think u need to reduce the inlet pile smaller. as u observe the

venturi, the air tube is at the narrow water pass thru side.

[ervine]

yeah I did that what..

[Oceandeep]

think of it... the problem lay on ur inlet.

cos u slow down the water into the needlewheel. By twisting the

inlet, is the same as close the valve of the pump.

I modifying a pump, change to needlewheel and air hose on the inlet side. Will pose a pict once I get the needlewheel done.

i have a weipro2012.. but i am using a pump which is used to pump water to the main tank from my internal filter and at the same time, pump to my skimmer... so how can i mod to see kopi'o' like yours?

try to insert a tude at the inlet but it affect the water going to the main tank since it is sharing..

on the other hand... it make the bubble in my 2012 bigger instead!!

[Oceandeep]

actually, u should chg to 2 pump, cos u may need to off 1 pump at times...

And I got the same effect as u(very big bubble).. stuffing air tube into inlet of pump.... so is not a full prove method...

so the best is still DIY needlewheel or injector....
