Yes.

The following: - Timer to turn CO2 on 2 hours before lights come on and 1 hour before lights go off. - CO2 proof tubing. - Some form of CO2 injection eg in line diffuser, reactor etc. - Ensuring your filtration rate for a 240litre tank is at least 2400litre/hour (x10 rule of thumb). -...

As pointed out you will not really be able to achieve balanced flow to two diffusers via a splitter. The CO2 will take the path of least resistance and one CO2 diffuser will dominate the flow. You need to split the flow before two needle valves so you can balance the flow to each diffuser...

This is what happens CO2 attacks and dissolves in rubber, as you can clearly see. Rubber is not ideal for CO2 sealing, but under low pressure sometimes survives...or not. You could try Viton or nitrile o rings as longer lasting alternatives. This is why you shouldn't put your CO2 diffuser on...

Be very careful about using silicone on plastic parts as in my experience it can often cause the plastic to craze and fall apart into millions of tiny peices...happened first to my bubble counter followed shorty by one way valve and obviously leaks...

I have had this and it is due to: - Long lengths of CO2 tubing between needle valve and rest of CO2 apparatus. The long length pressurises, the diffuser then "burps" out CO2, long length pressurises and it repeats every second or two. Make all tubing only as long as necessary. - Using none CO2...

If sodastream cylinders were dangerous, how would we all make our fattening soda if at each bottle change we would have to change our pants....:eek: Also you don't hear of Argos employees having issues, as the largest suppliers of replacement cylinders. There are far more dangerous things in...

Correct choice.:angelic:

I would be very very very weary about using a regulator of this type on a larger volume CO2 source. This type of regulator are prone to end of tank dump when the tank starts to loose pressure when nearing empty. This is not a problem when cylinder size is small (in your case 95gr) an end of tank...

So looks like the 1litre UP tank should be filled with 680gr of CO2. Two reasons:- 1. colder tank means less boiling CO2 (paintballers often put their tanks in the freezer first) 2. if it explodes you won't get impaled by flying shrapnel :eek:.

Probably. The fire extinguisher at work has 2.87KG CO2 stamped on it as its capacity. 2.87KG x 68% -> 1.95KG. Also got its weight of 4.87Kg which is the weight (with horn removed) when full of 2Kg CO2.

UP do state capacity in litres. http://www.up-aqua.com/00-dm-page/00dm_co2-all-big-2013.jpg However the link I sent before states liquid CO2 density of 1.03, this 1litre will weigh 1.03Kg, thus you & you filler are correct it should be filled with 0.68Kg gas and NOT 1KG. This might explain your...

I always thought a 2Kg FE was filled to 2Kg weight of CO2 but this is only 68% the amount you could get in. Relevant bit from link below here. " The weight of gas/liquid that the bottle should hold will be stamped on the bottle....NEVER exceed it. A 2 kg tank is designed to carry safely a...

The actual tank volume has enough volume to hold 1.47Kg of gas to the top, so 68% = 1Kg. So you put in 1Kg of liquid CO2 (at 55bar) and have space above the liquid acting as a "pressure buffer".

The graph below shows why you should only fill a CO2 cylinder to 68% of its volume (also 1Kg in your case). If you fill to 100% (no gas space) and cylinder warms up, in house, in car etc, you can see the pressure rises very quickly ie nearly 2000psi at 120F and much higher will rupture the...

The only reason (other than obvious safety valve tampering) for a CO2 to vent is overpressure due over filling, very common in paint balling world where they wish to have as much CO2 in their tank as possible and end up discharging their cylinders even before they get to play. As its only one...

A is cylinder pressure, which as it is pressure of the gas above liquid CO2. It will stay at about 55bar/800psi/5.5MPa despite liquid level and once all the liquid has gone the pressure will drop as there is only gas left. B is regulator output pressure 3 bar is 40psi is 0.3MPa. Yours is higher...

Excellent answer for OP.
