how to tune a marco 150NW skimmer?

[saf168]

hi,

I have problem trying to tune my skimmer to obtain skimate. these are the steps which I had tried - -

1) Position the skimmer/pump higher and lower

2) Insert the airstone in the inlet tube ( to make the bubble smaller )

3) Shifting the skimmer from the 1st , 3rd and now 2nd compartment (suppose to be the most stable water level ) of my internal tank filter

4) tilting the pump facing upward and downwards... because of the space constraint in my compartment..

How long have you guys been running the skimmer before the first drop of skimates flow out?

I am thinking of changing the pump to a higher capacity...

below are some pic of my setup

any advise is appreciated!!

pic of my present position of pump.... behind the skimmer!!

quite near to the surface liao.. i tried even nearer to the surfacebut bubble looks the same

pic of my bubble.. only occupy the upper chamber...

[saf168]

pic of bubble level setting... the water are overflow when i was trying to setup.. hehe not skimate

[saf168]

pic of the airstone which is insert in the inlet tube.. I tried the control valve too.. no improvement either... sian

[saf168]

pic of my outlet tube... tiny bubbles are minmised to zero!!

pic of my 2nd skimmer.. which is a surface skimmer .. but no skimate either!!!

Is my water really that CLEAN??

Hi Bro,

how many days of your skimmer ruuning since you kicks in.

brand new skimmer will takes couples of days due to some oil on parts like pump will makes it kicks it later.

I have mentioned others ways to tune the Macro skimmer in my thread recently. search for it and PM me and i can talk to you over phone.

cheers

try setting the water level to between the 2 white lines i've drawn.

if you want to see if your skimmer is skimming, blend some market prawn meat and then throw into the compartment with the skimmer, and switch off the return pump. then you will see if your skimmer is working anot.

i personally dun find it useful to put the wooden airstone at the inlet...

small bubbles r onli produced when it is used as an outlet....

by doing so, u r onli starving ur protein skimmer for its intake of air....

some findings.... i took the pump out and dismantle for wash... quite clean though... but after i put it back and on it -- smaller bubbles start forming and skimate foam was starting to form... hehe

will update if this work man.. maybe i should take out the airstone for test!!! hmmm

Hi BRo,

Finally u manage to fine tune!!1

Looking at ur pump, the inlet of water should face up instead of facing down. Hope this may help!!!

got some good tips from moxa, who call me through phone. Wow !! such a helpful reefer man... Thanks

Trying out some pointer like lowering the pump by extending the tube....

thanks again man..

any other pointer anyone like to share?

lowering the pump?

if my pump is on the bottom of the sump, my skimmer isn't skimming at all, have to put it about 3cm away from water surface. I think its crap design by Macro on this aspect because due to evaporation, the water level will fall to be very near the pump's inlet and there will be a loud ###### noise.

But i've also seen some reefers' macro and they have their pump all the way to the bottom and its still skimming well.

looks like there are a lot of lemons in their shipment.

Time to change skimmer liaoz.

hhmmm....AquaC EV-240 or the H&S F2001?

or the beckett from aquamarin?

what I notice is the bubble counts will drop after a few days of running...

The only way to restore that is to off & then on the pump .. anyone notice that ?

[manfromsg2004]

I have the same problem as u and the skimmer doesnt foam all the time. Some advice was to connect a air pump into the air inlet to aid the skimmer. have not tried it myself though...

Give up liao!!!

Think its due to my small area compartment which the pump is positioned.. Will get a sump tank instead.....

Hope it will work after placing in a sump.. If not , anyone interested?

, but has anyone tried upgrading the pump so that it becomes less dependent on height? Care to share?

you need the right size of needle wheel to match the pump .
