Nutrafin CO2 system

[fishmadpete]

Hello,
Has anyone used the Nutrafin CO2 system for aquariums? If so what were your results like? what size tank did you use it in. The packaging states it is for 75 ltr tanks. I have a tank that holds nearly 700 litres. I can't really have ten of these units hanging off the side!
Is there any other products on sale anywhere?

It works for smaller aquariums 20 gallons and under.

If my calculations are correct, you have over a 150 gallon tank. You really need a pressurized CO2 setup for a tank that size. DIY CO2 would be a pain.

yes but i found that the CO2 didn't last very long so heres wot u do.

get the defiser and the air line then go to ur machinemart or some place that sell bottled co2 (u wanna get the small ones for portable MIG Welder) then get a regulator for it and take the airline and plug it in u may have to get the pliers out cos the hole is too small and u need to pull a small clip that's in the fitting. Thats wot i've done and the results

Fish and polants are great. and it's cheaper

CO2 and regulator cost £15 and the CO2 is the only bit u change. I've had mine for about 5 monts and still on one bottle (i'm expecting it to last about 2 years the nutrafin system will be about £3 for 3 monts. and it's just like a presurized system but they cost about £60 but they do have a bit more stuff to it.

Many thanks for that info. What a great idea will probably give that a go. As I said above the tank is over 700 litres (150 Gall) so the nutra system is too small for it. However the local garden centre has knocked £7 off its retail price so will buy one just for the bubble counter
once again many thanks

Tropjunky, I'm unfamiliar with your currency/pricing, but I wanted to know if you're renting that bottle of CO2 and just refill it in the future?

I bought my CO2 canister and regulator (with solenoid valve, bubble counter) for about $250.00(US). How does this compare to your cost?

(I'm just curious, because you mentioned this was cheap. Mine wasn't cheap. Darn it!)

Hi,


The gas cylinder is not re-fillable. The price quoted is about $32 (US) for gas and regulator. The gas can be purchassed for approximately $16.
However it doesn't include one way valves (non-return valves), solenoids or piping.
THe bubble counter will be from the Nutrafin system which in the uk retails at around £19 ($30 US).

The gas is used in MIG welding (be sure to get only CO2 and not CO2 + argon). You should be able to get something similar in Sears or in stores selling home welding machines.

I have been looking for a suitable solenoid valve here in uk but haven't sourced one yet.
Be advised I haven't tried this method yet and will probably involve quite abit of trial and error

Regards

Ah, so it is a different setup than mine. My CO2 canister is a 5 lb aluminum, refillable cylinder. The regulator, solenoid, and bubble counter came as a package deal. I bought the CO2 cylinder at a local welding supply. On this particular setup there's a reactor in the aquarium. My yeast setups have hagen diffuser/bubble counters.

Thanks for breaking that down!

they're disposable and only cost about £10 the regulator is a v.basic one . It's just a knob that u turn no indication of the pressure but stull evvective i'm working on an adaptor for it so i can get a gauge on it.
