I didn't notice, but is the popular name for this device the "Paris Hilton" of diffusers?

cant be, I didnt get a crotch full of inverts with it.

Ooooooops.. this works better than I thought, yellow drop checker = gasping rainbows and unhappy oto's.

Did water change, increased surface movement and turned down the CO2.

How many BPS is going through this reactor ?? What are your water parameters ?? Size of aquarium ??

I had about 5 bps going through it, but the size of the bubble is about 1/2 the size of my old bubble counter, I know this cos of the position of the thumb wheel adjuster on the CO2 canister is 1/2 what it was with the other systems Ive tested. Ive turned it down to 3 BPS now, so Ill see what that produces.

So anyway, it looks like this is about 200% more efficient than that vario tower thing. Which Im very happy about. I wonder if this has to do with misting methods vs dissolving methods.

I have hard water, in a 37gallon tank.

I think BPS is a very inaccurate way of measuring input, as every bubble counter has a different sized exit appature, thus creating different sized bubbles. We almost need a proper flow meter on them to be able to compare.

So did the bubbles ever start going up the spiral?

hehe no I didnt think they would... I think the spiral is a kinda pushup bra, looks pretty, but when you take it out reality bites

I am no expert on push up bras, but I always prefer to believe that what you see is what you get. Anyway.....

Bubble counters are only useful to show you that you are maintaining a constant flow of CO2, not for telliing you what that flow is. Then, when you have to change CO2 tanks, and restart it, you have a number to shoot at.

Well I have the 105 version and it has largely filled with water, until the CO2 is turned on, then the top half an inch becomes a CO2 'vacuum'.

No, my bubbles don't go up the spiral. And I don't seem to be getting a fine mist of bubbles either - the bubbles appear to only want to exit from one point in the entire ceramic disk. I've had this for a couple of months, so it's not a 'break-in' period thing.

The clips supplied with the device are completely inadequate the clips aren't strong enough to keep the diffuser attached to the side of the tank.

I'm currently on the look out for another diffuser - thinking about the Rhinox 5000...

Totally agree with the clips thing, nightmare they are, on a stick. Sounds like ours work almost the same, except that mine diffuses ok, although I still think the bubbles are quite large.
