actually the 3 in 1 diffuser combines with diffuser+bubble counter+check valve.

Needle valve is used for fine controlling of the supply of co2. This is must for co2 system, running without difficulty. This is for safety of the fishes.
The miniature but reliable variety of needle valve is made by Festo having six month warrantee, price around rs725. The bigger and heavy variety starting from around rs 350.

with ISTA 3 in 1 diffuser I am able to tune CO2 @0.5 bps....

though I am not a fan of using 3 in 1 diffuser.better use all those bubble counter,needle valve and other gadgets separately.

how to make a DIY bubble counter?

Its pretty simple you need a small airtight container, Air pipe (length= according to your requirement).
step1. Drill 2holes in the cap of the size of the pipe
2. Insert those pipes into the holes
3. makeit airtight by filling the gaps u can use silicone or any non reactive glue i hd silicone so i used that only. a smallsilicone tube will cost aroung 30rs

ISTA 3 in 1 diffuser is not at all a reliable for counting the bubble. Achintya is very right .....the best thing is to use check valve , diffuser and bubble counter ....seperate .If ahobbyist has got some money problem then he can make a simple DIY bubble counter like we make one in the DIY CO2 as it give a much better bubble count. ISTA shows 5 bubbles (which are actually much smaller than normal bubble we count) where as the normal bubble counter shows 1 :) So if you count the ISTA one then its actually faster n confusing until you have good experience.

Thanks for the write-up Tirtha. Its immensely helpful for my research before buying a Co2 setup. The pics helped in understanding too. The warning and caution about safety were most thoughtful. Thanks again.

In a standard cylinder the pressure output is 1200psi n in summer increases to 1400psi. Check ur regulator gauge There are two types of single gauge regulators one of 1200psi and other 1500psi. If the gauge is of 1200 then its a problem bcoz A fully filled cylinder has higher pressure ie. beyond 1200.
its taking few Weeks to come under control.
During this time pressure drops below 1200psi and u are able to regulate it. Pls Send a pic of ur gauge to further help u.
