How Good Is The Nutrafin Co2 Kit?

[Nano Jake]

Before I splash out on a JBL pressurized Co2 kit I wondered if the Nutrafin kit would do the job for a fraction of the price.

My setup is a 60cm [60l] planted with loads of light. I realize high light tanks need lots of consistent Co2 but wondered if the Nutrafin kit would be up to the job?

Providing you can run two cannisters (and ditch the sachets to use normal yeast/sugar as per the pinned thread) and swap the mix in each alternately every 3-4 days to keep a stable output they are fine. I had this on a 60cm tank but got sick of still unstable CO2 rates and no easy method of controlling CO2 ppm and in the end splashed on a D-D pressurised setup, £100 delivered and much nicer long term.

That would mean having two ladders in the tank? cant see how you keep pressure in the system when changing...

Is the D-D better than the JBL easy set 1? does it come with a solenoid?

D-D has solenoid aswell plus needle valve, bubble counter etc though mine came with a powered pump and not a normal diffuser so for my 15-gallon I used a Dymax Ceramic Atomiser which works well (for about £3 via www.aquaessentials.co.uk).

When I say two cannisters I mean two cannisters linked to one ladder via tubing and a T-piece. You change the mix straight after lights off (or as far from lights on as possible) which gives it time to build pressure up again, though with a ladder there is little to no pressure build up required anyhow. As one mix is slowing down the other is speeding up so the CO2 output stays more stable than a single mix which starts slow, gets faster, then slows down so CO2 output is not as stable throughout the lifespan of the mix (about a week usually).

Sounds like it will work but loads of hassle, I take it having two gives you a more consistent flow? The kit is rated up to 70l but I guess thats for a low tech tank.

Having two makes the CO2 delivered more STABLE. Run them together but out of sync change wise.

You have to keep your CO2 (levels in the water) STABLE.

PS, did I mention the word STABLE?

Ok STABLE it is then!!

Sorry to be dim but exactly why do you have to keep the co2 levels in the water stable?

because other wise you get algae. almost all algae blooms of almost any kind are the result of co2 deficiencies be it a lack of co2 or a unstable supply
