hagen co2 system

[fishyfeet]

I recently brought this system for my fluval duo 800, I was just wondering if anyone uses co2 in their tanks and what system they use, heres some interesting info i put together for a review.

About this system, it has been designed to supply a aquarium with a safe, economical and efficient method of providing the plants with a carbon source for plants. In uses the natural fermentation process for co2 and eliminated the need for inconvenient pressurized cylinders.
The system allows quick easy and economical refills of ingredients of provide continuous co2 for a 3 - 4 week period. The special fermentation canister has been developed to support consistent carbon dioxide output.

Carbon Dioxide is the most easily assimilated carbon source for plants. Approximately 40 to 50% of dry weight composition of a plant is carbon.
Through the invigorated growth of aquatic plants, the aquarium owner can expect a higher degree of water quality. Many undesirable elements such as nitrates and phosphates are consumed by plants, providing a strategy that effectively starves algae, preventing and or controlling its growth.

CO2 benefits fish due to improved water quality, and also provides a safe and gradual method of reducing ph values. Many aquatic plants thrive in mildly acidic ph ranges, and suitable species of fish for planted aquariums often prefer these conditions.

I have to say there is marginal improvement in the growth of the plants, but think its more suited to a smaller tank, i dont use the packets of mixture you can buy, what a ripoff, and mix my own receipe using brewers yeast.

Right i think thats it, any questions, di

i personally don't use CO2, but sounds great...

I think its definately of benefit for a nice planted tank, you need to get a more industrial unit though for larger tanks, this is only suitable for less than 20 gal,
but its better than nothing, the other thing is, it doesnt have a regulator, and really should be switched off at night, with this unit there is no way to turn it off or adjust it in any way. di

i have to cut back plants often as it is lol if i had CO2, my tank would be a jungle!

I have one of those!!! They are brilliant for smaller tanks, around 10-25 gallons. Anything bigger you would probably have to either get 2 or go for pressurised CO2. Anyway, My plants are so much healthier in my tank since I added it

Personally I wouldn't buy one. Depends on the price. If you need CO2, I would recommend a DIY CO2 input, especially in smaller tank (under 20gallons). If you decide not to buy it, then the best alternative to CO2 is fertilizer. However, it also fertilizes algae.
