2005 Macro NW Skimmer

[acidjazz]

pardon my ignorance...

(1) how to modify the marco (details please?)

.

(2) what are sanders? - air stone har?

.

(3) Which 3500l/hr pump (brand / model) you refer to, available in the local LFS?

- can this model fit the current macro pump's needle wheel?

- or the 3500l/hr is already a needle wheel pump by itself?

CHEERS!

bro, its difficult to explain in theory how to mod the macro, need to hands on. .

sorry for not stating specifically, yes its sanders air stones. I believe it will help increase the bubble count and hence increse the efficiency.

Only seen the new macro once, can't quite remember how's the design. Hence can't tell ya which pump to use. May the other macro users step forward and share ur ideas.

Thanks. if you meant modifying the marco to accomodate 2 air stone, then i think i know what to do... but does increase the bubble density by using air stone improve the efficiency of the skimmer?

[rshut]

how to accomodate 2 air stone in the skimmer?

Not sure about your new model, but if i were to modify mine..

(1) i can drill a hole at the collector cup where by the air tube can go thru' and all the way down to the bottom of the skimmer with an air stone attached at the end of the rubber tube.

< or >

.

(2) don't bother about modifying the skimmer, buy a large-enough L joint (those use for piping), capped one end of the L joint over the in-take of my current NW pump, while the other end of the L joint is facing the bottom of the sump tank. next place the 1 or 2 air stone(s) just below this end of the L joint, the bubble from the air stone will then be suck up into the NW pump into the skimmer...

hope these ideas work...

THis way , the collection waste will be reduced as there is a tube

bro rocks. your second idea sounds good... =)

hehe..

hehe..

thanks...

its not proven, but i hope to give it a try... so ... first must go borrow a air pump and buy some air stone ...

or anyone one out there has a Macro skimmer, air pump, and air stone to give it a try ?

CHEERS !

bro, will fix my macro tmr and show u the pix if possible.

that's great ! ...

thanks a million !

p/s: for experimentation, actually no need to buy the L joint (if you do not have one) just adjust the NW pump where by the in-take is facing the bottom of the sump then the air-stone right under the in-take of the pump, as such most of the air-stone bubble will be sucked into the pump..

I tried it out last nite...hmmm...i'll post a pic 2nite...

so was there any obvious improvement on the density of bubble in the chamber?

CHEERS!

[rshut]

there was a bit difference in the density of the bubbles...but my air pump not strong enough...old pump i must say....i think changing to a higher capacity water pump should be better...what do you think?

So the diff not much har? may i know whether you are using 1 or 2 air stone, what is the air pump size you are using ?

Changing to a higher flow rate pump, i think should be much better.. but I don't think you can find needle wheel pump (abv 2000 l/hr) sold in local LFS seperately.

CHEERS!

[rshut]

i'm just using one airtone...ur rite...me too not sure if there is a NW pump wif 2000l/hr around...

[giantbicycle]

get a higger capcity NW pump , that will solved everything

[rshut]

the problem is...whr to get a higher capacity NEEDLEWHEEL pump?2000l/hr and above?

[giantbicycle]

aquabee. get from online.

[dainese]

the problem is...whr to get a higher capacity NEEDLEWHEEL pump?2000l/hr and above?

DIY lah bro...get a cheap external pump and try see how 1st.

if need help can call me.

I am no expert on this skimmer, but have used a Turboflotor 1000 for many years which is a similar type.

Your first problem is it looks like you are using a hang on skimmer in a sump, i think the sump model would be better.

The hang on skimmers work best when the pump is placed as close as possible to the inlet and as close as possible to the water surface. Firstly this reduces the head pressure on the pump and secondly the water pressure which allows more air to be sucked in.

[somebody]

where's the pics? where's the pics??! =)

hmmm... but wouldn't there be a chance that the inlet is so filled with bubbles, that not enough water run through it?? creating a complete air space in the pump? and causing a need to restart?

I tried it out last nite...hmmm...i'll post a pic 2nite...

any pics ?

[acidjazz]

bro, ytd just fix up the macro. tonight will take pix. .

[rshut]

HAving a bit of a problem....my air pump stop working...

[somebody]

what a downer... =(

hope you can get it working soon!! =)

wanna see how it goes...

[acidjazz]

the macro in action. powered by a sicce extrema. my apologies tt i cant take the design of the entire macro unless i dismantle from the sump.

*note tt i haven't add in the air pump yet*
