The item you've listed is just the bubble counter (#4 in the diagram), not the whole system. It's pretty, but it's only 1 piece of the system.

If you're not wanting to spend lots of money, a bubble counter can be made out of a water bottle and a little bit of tubing much cheaper than the price they want.

ok what about this difuser is it aby good?

That looks like a nice diffuser. You have to be careful with them if you use DIY (yeast method) co2. It doesn't always generate enough pressure to work with glass diffusers....and can cause built up pressure in the bottles...not good! It does sometimes work though....won't know until you try it.

any more advice would be much appreciated

i just use an airstone...since i heard over time those glass diffusors get clogged up...
but those diffusors must be worth it since they are in the market for long and people keep buying them for DIY set ups

 

[oliver moggridge]

yes ive herd that too, but ive also herd that airstones are a waste of time! so im in two minds weather to get it or not? is there any other defuser that is good?

Another option is to put a piece of bamboo chopstick in the end of the CO2 line. Bamboo is very porous and will break the gas into a fine spray.

Just about as cheap as you can get, of course, you'll have to treat yourself to a Chiness dinner first. Oh Well!

ok cool ive found this and wondered how long it will last for and is it worth buying?

If you have more than a quart sized tank, no.

if you dont want to spend a lot of money make a diy co2. going cheap just doesnt cut it there is a reason why many people do use them. in the long run they cost a lot of money or just not worth it.

I would recommend the Dennerle diffusor: Co2-Systeme im Überblick
I don't know how much it costs in the USA. It dissolves CO2 very good.

that diffusor looks like the one in hagen nutrafin co2 system...
people have told me that type does not work very well...but maybe this one works well
i use DIY CO2 with an airstone...
are these CO2 diffusors and pressurized CO2 system worth the cost?

 

[Andrey]

I can't compare because I haven't used any other systems. Nevertheless in my opinion the effect of using this diffusor is very well, my plants are looking healthy and their growth is also good.
