C02 For 75 Gallon Aquarium?

[b0b95]

What is a good c02 system for a 75 gallon aquarium. Looking for less than 150 dollars. Could I use 3 nutrafin c02 systems? Or are they crap. Right now i have a 110 watt light, and am planning on upping in to 220 watt t5 fixture.

For the price of 3 nutrafins your better off looking on ebay and finding a pressurised system, esp in a tank that size.

okay. any really good pressurized systems

Hagen Plant Gro CO2 Natural Plant System 8 dollars apiece. Is it a really poor system? and yes it is not pressurized i know

In your tank if its not pressurised its useless, well anything really with a decent sized refillable bottle, a 95g disposable bottle wont last 2 weeks in your tank lol.

okay, i will be on the lookout for pressurized systems. should i get one more 55 watt t5 or two more lights to combine to 110 watts.

 

[stevereade]

Well you want about 2wpg really.

could i use flourish excel instead of pressurized c02

It's a big tank, it'll cost you more in the long run to use flourish than it will to buy a decent co2 kit. You're also intending on adding more light, well you'd have to add a unfeasible amount of liquid co2 and it still wouldn't be as effective as pressurised co2.
