not seen the vista diffuser you are talking about.
have you seen it action?
however, 100% diffusion rate would mean no co2 bubbles will rise to water surface.
algae seems to grow anywhere it likes, even on smooth glass walls.

Anybody here have comments/experiences on the Vista Stainless steel CO2 inline diffuser? It claims to have 100% diffusion rate and is also impervious to algae growth. I wanted to know if anyone have checked out the truth of those claims.
Warm regards,

Have not seen it in action, but the claims sound really good. Especially the No algae partIt's a Taiwan made plastic thing that can be used inline or in tank.

most, if not all, products claims some sort of 'special' capability/ies.
else how do they differentiate their products from their competitors.
you'll have to try one in your tank to verify the algae claim.
and if you do but one, do post your review for the diffuser. especially the algae claim.
GaspingGurami,
So is the diffuser made of stainless steel (as described in your 1st post) or plastic (2nd post)? Or is it a plastic device encasing some kind of stainless steel mesh (i'm guessing)?
The claims may actually be true - Their diffuser, at least the inside of it, may actually be resistant to algae growth if it is enclosed in come kind of casing.
Then again, sprinkle some gravel on top of a normal inverted bell ceramic diffuser and one can keep the white ceramic plate algae-free for months, if not years.

You guessed right. It is a stainless steel kind of cylinder inside, which I guess must have microscopic pores to act as the diffuser and encased by a clear el-cheapo plastic casing.
My guess is that CO2 is injected to the "dry" chamber surrounding this SS cylinder, and is diffused thru the cylinder into the flowing water connected in-line with the cannister filter's outlet hose.
The logic of this diffuser seems workable to me, -- no light = no algae -- provided there is indeed the technology available to make a gas permeable SS tube. However, the quality of the plastics holding the whole contraption together looks highly suspect.

Firstly, I dunno whether algae can still grow in the absence of light. You see, them alga specie are survivors having come so far and lasted for so long. They can even grow in the hot sulfur water of a geyser! But if they can't survive in the absence of light, then the manufacturer's claims are truthful.

True, but wouldn't that make big bubbles which defeats the purpose of a diffuser?
Actually I like the idea of an inline, as I'm trying to reduce the number of tubes etc being stuck to the walls of the tank -- I have an aversion to things stuck to the tanks walls -- this tank used to be a luohan tank with "Little mermaid" stickers plastered all over its 3 panes. Yuk.

Most algae require light for photosynthesis. There are exceptions though - Some algae can make food in the absence of light but they have other requirements instead. E.g. Micro-organisms near deep sea vents rely on Hydrogen Sulfide since sunlight can't reach them.
Most (if not all) of the algae we get in our tanks should be photosynthetic. That's why we don't find colonies of BBA or hair algae inside our canister filter though BBA love to grow on rainbars, esp at the outlets.

Not when I last tried it.
