hermit diy spray injec skimmer............

[RAV-65]

no injector dun works same to beckett....................

it works by spraying water onto water surface to form bubbles................

if it is place so high(longer piping) pressure will loss hence cant produce enough water pressure to spray more bubbles...............

but i will try out also.............

any way i havent glue the piping yet..............

i also think tat the riser too high liao...........

no choice leh..............

the union is tat size lor..............

wan to get a better pump to run it lor...........

thks bro Rav-65

No prob... thanxs for the info too, I tot beckett same as injector!! Good luck on your project! It's looking real good!

shift the gate valve to the side...and extend the pipe...

the baffle plate, extend it as shown to maximise contact time....

my next set will be like that too...

my 1st set, i used a baffle plate much like BARR AQUATICS' style...but not really foaming well...should have listened to my neighbour...hahahaha....

now have to waste money on laser cut again...anyway, i have spare acrylic, if u want, we can laser cut together...do a real nice professional set...u want?? then dun need the gigantic union, can just use o-ring...much neater....

when are u working?? i will be quite free after tomolo...jobless....hai....

oei! wad y drew on the mixing box!?!?!?

look like a.......

OI!!!! dun disturb hor...there are young kinds in this forum...dun corrupt them...hahahaha...

the left piece is the baffle plate and the right one is the gate valve's position!!!!

[reeflobang]

nice work bro...hhahaha

i haven;t even done my own yet....hahaha

only did one so far, with my bro-in-law right now...

I am his "guinea pig" brother-in-law testing his skimmer now.

Review so far:

1. Foaming comes and goes. Noticed that after feeding, the foaming stops and comes back after 5-6 hours later...

2. Bubbles are trapped in the bottom chamber and soon forms huge bubbles that rushes up the reaction chamber and disrupts the foaming process. Some kind of baffle may be needed to prevent this from happening.

3. Using a 2200l/hr pump now and the water level is sometimes unstable.. getting a 3000l/hr pump to see if this helps.

4. The air intake valve is not working - bubbles rate is the same whether its fully open or closed.... ?? Am wondering where the air comes from then when the valve is fully close.....

5. Gasket is leaking badly if they are tightened by hand. Need to use pliers to really tighten the screws and the leaking reduces... (still leaking!)

Pic of the foaming attached. Taken from my phone so is not that clear.

good job bro!

Hmm the skimmate looks like green tea. Maybe if possible tune to get drier skimmate.

[reeflobang]

Still tuning the skimmer to get dryer skimmate but not easy as :

1. Cannot control airflow for now

2. Pump is probably too low in capacity

See what happens when I get the 3000l/hr pump.

i didn't seal up the spray nozzle that's y there are leaks even though u closed the air intake...i'm afraid that the nozzle dun work well...since it is ok, i think we can seal up the thing...but wait for me to do it...okok?? still have another nozzle for u to test out...

the traping of the bubbles is due to the baffle plate design...will try to solve that...but need to dismantle the whole skimmer...

as for the o-ring, i've got no idea y issit leaking...no such problem for my other units, my FR, becketts, no prob at all...maybe the contractor cut the groove too deep...will get u a thicker o-ring...

lets see if rio3100 will have better effect, it is the recommended pump for AquaC EV-180...lets see if it works better...

[reeflobang]

yeah, my bro-in-law is doing a new one for me... hee hee.... happy for now till he send me the bill......

But that's when I will bring in my finance controller... his older sister! ha ha!

cannot tell jie jie hor...if not both of us die...just say, $50 will do...hahahaha

test test test still putting my skimmer on test.......................

alter the setting alot of timesee can get better off result anot................

bro wat pump are u goin to buy?????????????

saw a pump call multi 4000 cost ont 98bucks at aqua star...........

goin to return my atman pump and may use it to run my skimmer also..............

[typrobin]

he is using a normal china pump...2400ltr only...now got a new rio3100...3000ltr...still running the test in my house...

i full blast the skimmer by fully open up the air line valve and level down the water level to the reaction chamber and saw the the foam was dam thick..........

problem is onli wif the water is somehow too turbulent liao............

maybe due to the pump.............
