hi,

i can't remember the site, but there is one that shows how to construct Tom's internal venturi reactor using the viewtainer, with pictures. the first step was to discard the bottom (the non-slitted one). can anyone direct me to this site? i've searched the forum here and on plantedtank and aquaticplantcentral, but cannot find it. i also checked back in my history, but could not find it either. thanks.

It's here actually.

And more here:

Note small 3/16" burp hole on opposite side of the venturi.
The viewtainer is 4"x2", cost 1.99$ at OSH, Home Depot etc

Rigid airline tubing is 69 cents for 3 feet.
Rio powerheads about 8.99 or so on line etc

I use the lighter to melt the holes into the sides.
The suction cups holes as well.

The top is cut with a X shape and tightly wegded the Rio 180 elbow in there and then snap on the powerhead.

The rest is self evident, look at the pictures and do that.

Tom,

thanks for the quick reply. i saw the pictures you just posted. i was referring to a 'how to' , with pictures.

btw, what you refer to as the top is in fact the base, is it not? the top has the slit, the base has the 4 'feet'.

Does it look 4 feet long?
There's no ' apostrophe behind the 4, it's just a typo.

It's as simple as looking and doing, there's no need for detailed step by step instructions, if you messed up, then the veiwtainer cost you 1.99$ to make another one

Everything is there and laid out.
Every orientation is shown.

I have attached a word doc with a detailed drawing as well.
If you are into DIYing things, you should be able to figure it out, it's a simple device.

DIY internal Reactor, great for Yeast CO2 users!

Still looking for what Greg did with that Word Doc I drew.
Op, found it

let me be more clear: it appears you are using the end cap that has 4 foot-looking things molded into it. i think you should edit step 1 of your word doc from "The bottom removal part of the viewtainer is discarded." to "the bottom end cap (the one with 4 foot-like things molded into the cap) should be retained and used in the following steps. discard the end cap with the slit."

it became obvious to me that the bottom should be used and the top discarded. my reason for asking about that pictorial how-to site was that it also said to discard the base.

this may be misleading to those who may not be too diy savvy.

thanks.

ps. they cost $2.79 now

Haha, I ain't that clear sometimes either
Dang, i knew I should not have said nothing, they went and raised the darn price to 2.79!! Them ratscallions!

Yes, I went back and changed the ' in the last post.

Thanks for the comments.

Now go make one and see.
Them go bug other folks and show them how.

possible project for this evening. i might also try to make one with co2 input to powerhead's venturi (similar to rio) and attach the reactor's venturi line to input of the powerhead.

i'll see how it compares to my japanese-made reactor that has the co2 input at the top, water coming in tangentially from the top, bioballs in the body of the tube, and tangential output at the bottom. it's made out of clear green plastic. it does not seem to be terribly efficient, but most likely a function of diy co2.
