My nearly complete skimmer

[typrobin]

hi all....with a lot of help from my neighbour cmswong, i finally did someting right....

this is the spray injector

[typrobin]

in my sump...

[typrobin]

GOT FOAM???

this is after 12hrs of testing....

still trying to adjust the water level accurately, now using ball valve, so its quite difficult....

the best thing is the foam is building even though i have only 2 fishes....1 small bi colour blenny and a cleaner wrasse.....

[typrobin]

thinkin of making this

with 2 X spray injector and larger and taller reaction chamber.....any volunteers??

[jesperlam]

Wah so late dun sleep meddling with skimmer!...

Anyway nice work dude!

[typrobin]

look very pro rite?? hahahaha

but actually v ugly coz i use silicon to seal up the joints....not suppose to as it will leak....that's y i put it inside the sump....

[rockfish]

hey bro!! .. can show wat u use for spray injector .. and where u get it,how much .. ??

[typrobin]

this is the spray injector loh....

u might wanna take a look a this http://www.geocities.com/jeffsreef/DIYpages.html

like an aquac skimmer.......looking good

if u need help to diy, or kaki.....i can help we are neighbours anyway too

looking for volunteer to be my guinea pig....for next project....dual spray injector....

[Golden Tooth]

I can or not?

[typrobin]

I can or not?

u've got PM

[typrobin]

DR Evil, i believe i should probably need your expertise...

[ryz]

AHH... how much it cost u?! how's the skimmate like??? I wanna try leh. can help? haha

[typrobin]

AHH... how much it cost u?! how's the skimmate like??? I wanna try leh. can help? haha

the lousy one tat i am using cost about $150 of material....excluding pump....

the next project should be around $300-400...not too sure...haven't calculate

so far no skimmate...i think becoz i only have 1 fish left...

[typrobin]

currently Reddevil and golden tooth volunteered....

pls note tat i am not selling the skimmer....juz testing out, and volunteers are paying ONLY for the material...and some transportation fees to me....purely a non-profit experiment...

[typrobin]

just tuned the water level even lower....will let it run for at least 1 week without touching it...will see how....if got thick kopi then maybe will start new project....

[moron_clown]

good job!let me noe of the progress..perhaps i will invest in a super-sized spray injector skimmer instead of the beckett..

alrite....will update...

[Golden Tooth]

Yeah. Me looking forward for updatez too.

[hermit]

me too.............

[typrobin]

just discommisioned my skimmer....after a week of testing, only produced a little tea....very sad....

but i will be back for more!!!

Red Devil, Golden Tooth and Moron Clown pls be patient....will show u guys solid proof before making u invest in it....dun think u guys need the skimmer so soon right?? will keep u all posted....

gimme another 1 week....will show u result, if not, then i will not carry on with project...

[Golden Tooth]

Alrite bro.. Thx.

You might wan to try letting the injector spray directly on the water surface instead of routing a elbow into the reaction chamber. This will help creates more bubbles.......unlike the beckett or any venturi injectors, the air and water is already mixed upon exiting the beckett/venturi injector, thus you can route an elbow to the reaction chamber to form a swirl. For spray injector, the bubbles are form only when the sprayed water hits the surface of the water, therefore the use of a baffle plate to guide the bubbles up to the reaction chamber & also to prevent air bubbles from escaping to the outlet flow valve.

IMO, for thickness of the skimmate, the key lies on the water level in the reaction chamber.

Too low - the skimmate will get stuck on the surfaces of the reaction chamber or the bubbles will burst even before reaching the top of the collection cup therefore collecting not much skimmate.

Too high - definitely watery and tea light skimmate.

By using a more powerful pump together with a bigger outlet flow valve to control the water in the chamber at the right level, you will attain nice thick kopi 'O'. Of cos if you want dry skimmate, then you have to figure a way to get the smallest bubbles.

Above is just some personal experiences while playing around with my tupper skimmer & lots of read up...........don't give up, your skimmer is definitely of high potential, just need some fine tuning..........

ERIC!!

that was exactly wat i discovered as well...that's y i took it off and planning a new project....thanks for the advise...wil keep everything in mind....thanks again...
