CO2 contraptions- Red Sea

[fusQuanto]

is anyone familiar with the red sea co2 injector? is it worth buying?
it has a powered head that delivers the co2 into the aquarium, sounds
like it would suck in lots of co2 too fast, thus making you buy new
product to refill it for $$$. of course, id use the DIY yeast method
thereafter.

also at petsmart they have this other co2 contraption that is very
similar to red sea's, except the delivery method is similar to one of
those gumball machines delivery thing where the gumball goes round and
round and round before dispensing. the idea is to let the co2 bubble get
absorbed by the water as long as possible. however, the red sea one
does not account for this. is this marketing hoopla or is there some
biological basis for it?

I am using red sea co2 now. Of course, i am using DIY yeast after I ran out
of first refill. In my opinion, if i could do that again, i would have spent
more to get a pressured co2. It is much easy to control and doesn't need
refill every 1 or 2 weeks. Also it is not as easy as DIY co2 to cause algae
problems. Hope it helps.
