Hi guys ,

just soource for the design for the design of a Beckett 1408 injector PS ... would like those who have done one to comment on it ... pple like rrrobt , alvy , phang ...... anyone who can offer some opinion ...

thanks

[newdamsel]

Just wondering, how you guys manage to DIY the rounded tubes and shapes for the desired design?

Just wondering, how you guys manage to DIY the rounded tubes and shapes for the desired design?

u can either get the pvc/acrylic tube from local plastic co. they'll also drill or glue them for u. Otherwise, u can get them to cut/drill according to ur measurements and u glue them together yrself save money

hi guys ,

like to know the performance of H&S PS selling at Sealife ..... good/ average/ so-so .... ?

anyone using them pls feel free to response ... think AT , and a few guys using it ....

thanks

The air hose and green air valve is not sufficient for the amount of air a beckett will take. It will make a lot of whistling noise. You will need a larger hose, something like a eheim 16/21 or so with a valve.

[robe]

THe air intake will depend on the pump driving the skimmer the more powerful the pump is the more air it will draw. Actually you need to balance the pump flow rate with the skimmer riser tube. 6" body and 4 " foam riser will require a more powerful pump in the same league as the Oceanfree 9000 (it seems to me that Qian Hu OEM it from the same manufacturer as what they sell in the States as Sen 900).

If you reduce the pump flow rate to 3000 li/hr the air intake requirement is not as much and a green air valve can be used ( I am using it myself as it enable you to fine tune the foam in the skimmer).

For a 3000 li/hr you may need to reduce the foam riser to a 3" diameter pipe as there may not be enough flow rate to push the foam up the tube. If you put too much air to compensate for this, the bubble formed will be larger and not as fine as restricting the air. It also may lead to too much turbulence resulting in an unstable foam formation.

There is another issue of concern...

Was wondering the flange area between the 6 inch body and 3 inch riser... Wouldn't it be a trap for the bubbles formed and result in them forming together into larger pockets of air????

Figured that a 6 inch body to a 4 inch riser would hav less area for this foam trapping...

Unless the skimmer body is 4 inch...

Is a 4 inch body suitable in the first place??

It will depend a lot on the pump you use to drive the skimmer. Bigger pumps require bigger diameter pipes to contain the volume of foam produced whereas smaller pumps will require a smaller diameter pipe.

decided to get the H&S skimmer in Sealife ....

that is the most inovative skimmer I ever seen, but if you look at the skimmate, it is very light brown in color and very much water, which means, it is not very efficient at all. I am impress by the thought though.

[Tanzy]

I don't see bubbles in the skimmer chamber at all. I think the chamber is too big.

[Achilles Tang]

Looks totally inefficient to me.

I don't see how such a short and weird neck could function as a foam riser section in a normal PS.

The foam needs enough space to 'cook' and be pushed out.

Tanzy's rite... there izzn't enough bubbles in the body. It should be almost white with bubbly foam.... to maximise interaction with organic molecues in the water for them to 'stick' to the air bubbles that goes up and out.

I don't see that in this DIY skimmer.

[spade]

i'm not making this one, that's for sure

[Phang]

It will depend a lot on the pump you use to drive the skimmer. Bigger pumps require bigger diameter pipes to contain the volume of foam produced whereas smaller pumps will require a smaller diameter pipe.

Robe,

Kind enough to rate the l/hr required to run a Beckett SKimmer with a 6 inch reaction chamber and a 4 inch riser???

was thinking of a 3 inch foam riser but was concerned with the foam being trapped between the 6 to 3 inch flange.....

That's what happen with my last design.....
