This time is UP Aqua Inline SUPER Diffuser
- You need a canister to use this
- You need a proper co2 system with 35psi for it to work, anything lower it might not work at all
- This item is not cheap, around 40-50 in shops, i manage to get lower from online shops though... if it does not work in your tank, it might be a waste of money.
- the co2 inlet is quite brittle, might break off easily, my friend's diff actually broke off 1 week ago..too bad, but can be epoxy back of course.
- there are various size available, OPEN your eyes big big and look at the top right hand side behind the packaging for pipe size
