 |
|
Hi Folks
Just wanted to share, Myself, Anand & Arvind Shetty were at Chor Baazar to pickup some liquid cylinders which we could use as CO2 cylinders for our tanks. Attaching s few pics of the cylinder what I picked up and is same as to the one taken by Anand.
The cylinders were bought for xxxx each. (I think it should be okay to share the price, if not mods please delete)
I got the cylinder checked by a person who refills Co2 (medical grade) and to what I have been told that its been a very cheap deal for us, he think the cylinders are good and also the cylinder valve is looking good. I am expecting the filled cylinder on Monday evening.
Few pics of the cylinder what I picked upïŠ

I know I have to buy a regulator, is there anything else that you would to pick up for to start using the CO2 set.
Thanks

Fixed up the URLs for you.
Apart from the regulator,
You would need a Needle valve for finer control of Co2 release.
A PU tube to carry the Co2
Connectors to connect the regulator to tub/tube to needle valveve/Needle valve to tube again.
The number of connectors may vary as per your connection.
Check out yellow pages and look up for Welding Suppliers for the regulator and look up for Pneumatic Suppliers for the Tube/Needle Valve and connectors.
Over above, you may or may not need a solenoid valve.

The CO2 cylinders you have got are Fire Extinguisher cylinders. These have an internal tube from the valve that leads right to the bottom of the cylinder.
This tube must be removed before you use them for aquariums. It might have been removed by someone previously, but you need to double check.
Getting Liquid CO2 into your regulator is bad business and dangerous.
Take this small precaution and everything else will simply fall into place.
Enjoy! |

I guess, we get liquid CO2 only when we refill the CO2 tank.
Could you please explain why liquid CO2 is bad! |

You get liquid CO2 when you fill the cylinder that is always the case.
But what passes through the valve into your regulator is the gas from the top of the liquid.
Water expands to 1700 times it's volume when it becomes steam at atmospheric pressure.
Do you want to guess how much liquid CO2 compressed to 58 times atmospheric pressure will expand when it comes out of the regulator at 1-2 bar?
If you don't want to guess, do a google and do the calculations.
Lastly and more importantly Gas Pressure Regulators are designed to reduce the pressure of the gas, operate with gas and never with liquid. |

Thank you Sir!!!
As advised, have called up the vendor and have asked him to remove the tube.
I am apying around Rs 120/- per KG for medical grade CO2. I feel i am being overcharged.. what should be the right price..
The address of the place where the CO2 cylinders were picked up wil be posted by Anand (please do the honours) for other fellow aquarists :-)
And to summarise all, special thanks to Arvind Shetty for letting us know about the place which saved use quite some amount of money!!! 
Cheers!!!
Harpreet. |

120 rs a kg is 6 times what I paid when I refilled my tank last in Pune.
I don't know whats the current rate.I am told that there is a shortage for the gas and moreover the refilling facility has shifted out of pune city so the price might have increased.
But 120 is quite steep.
why dont try for industrial grade Co2. That will be cheaper I guess.
Is the Co2 refilling guy the same as from whom you bought the cylinder? |

is there any safety issues concerned with these cylinders?
i also looking for refilling but all are quoting rs 250-300 for refilling a 2 kgs cylinder.
also hardly any1 knows how to remove the tube.
any mumbai guys knows a place for refilling co2 cylinders ?
no welder knows what is carbon di oxide.they just know oxygen

Thanks Rohan!!!
Its think its my first time, am happy to pay that. I presume it will last atleast 3-4 months during which I'll search for a cheaper place...
Few more questions:
1) What about regulators, the guy has medical regulators which were priced around Rs 1600+ and on my request he will be geting a few cheaper ones which should be around Rs 800/-.
2) Is bubble counter necessary I can always DIY it right usinga small transperant bottle, correct?
3) Please suggest moe some good reactors (for a 26G tank). I intend to use my current Boyu 200ltr/hr power head for some time, do you think is it sufficient or reactors would always be a better choice... Are ceremic diffisuers good enough...
Thank you
Harpreet. |

Well CO2 Fire Extinguishers are designed differently depending on where it is made.
In some cylinders the tube is integral with the Top Valve in which case you have to replace the entire Top Valve assembly to one without a tube.
The second is the easy route, simply remove the tube after removing the valve, fit the same valve back. |

I'm guessing that you are getting your CO2 filled from Metro gas at Saki Naka. He sells regulators for appx. 1500/- (Bright brand). I dont know how much you got your cylinders for but you can get reliable ones from the Metro chap. My cousin just bought one a couple of weeks back since he didn;t want to wait for the shipment from Delhi.
If price is an issue, you can get the Eagle regulators shipped from the manufacturer in Delhi. It cost Rs.900 with shipping about 2 years ago. The address and contact number are in one of my posts (search for eagle on IAH).
Other pneumatic stuff you should be able to get at any Pneumatic/hydraulic stores. There are a couple on the road leading from Mahakali junction going up to MIDC.
Filling my 4.5 kilo cylinder costs me about 300 bucks with him (medical grade CO2) but I find it safer than handing it over to a welding shop for filling plus I find the convenience of an instant swap better than handing over and waiting for a refill. But thats just my opinion...
Bubble counter is not necessary and a well designed DIY powerhead reactor works very well...
Regards,
Venkat |

Food grade CO2 refill charge is Rs. 27/- per liter in Calcutta.
And even there are few people who charge Rs. 100-200 also! |

Hi
The guy I am going to is on the back side of InOrbit mall, Malad (w).
He is actually more of a medical supply guy (not a welding guy), so i have no option but to go for a medical grade gas.. although I have asked him to use cheaper gas for me incase he can get a little lower grade... But he seems to be little worried about the fishes and advised me to go with medical grade...
Venkat: Thanks for your input on the regulators. I'll post what I can find with him...
Thank you
Harpreet. |

Harpreet,
Welding Grade CO2 - about 99% pure
Food Grade CO2 - 99.9 % pure
Medical Grade CO2 - 99.9% pure with extra care in storage and filling.
My chap either fills up my cylinder with Food Grade or Medical Grade CO2. Cost Rs. 600 per cylinder weather it is my 22 kg cylinder he is filling up or my 9 kgs cylinder he is filling. Nowadays he brings his truck with a huge storage cylinder home, and fills my cylinders at the gate.
Depending on what grade he is carrying on the particular day I get Food or medical grade.
During Summers price of CO2 escalates as demand for soft drinks and beer shoots. It goes up to 100 + per kg in Bangalore. I don't know how Rocky measures CO2 in liters. 
More than the cost of CO2, it's the labour charges that are high along with transportation. |

Without freezing?
Bangalore people are lucky in every terms.
Here in Kolkata, they take 7-10 days to refill the full cylinder and for delivery within 24 hrs, you get only 75-80% refill cylinder! |
