Qn abt equipment

[jansonx]

Can anyone pls kindly advise me the difference between these equipments.
1) Bubble counter
2) Diffuser
3) Reactor
4) Atomiser

A shop near my house is selling a CO2 set at the price of $128,
1) CO2 tanks (2L)
2) Manual regulator
3) Air tube (1.5m)
4) Atomiser
5) Liquid Fert
6) Fert. (Stick type)

Is it worth it?

bubble counter - provides an indication of co2 bubbling rate
diffuser - devices such as glass spiral diffuser and flipper, co2 diffuses into water by contact time
reactor - 3 ball reactor, co2 is introduced against water flow and uses turbulance to break up a big co2 bubble into smaller bubbles
atomiser - co2 is forced through a ceramic plate to produce tiny co2 bubbles

try visiting a few lfs to compare prices for a co2 set.
