No CO2 Large Tank?
Someone else ask the question, what is "Large". Considering most average home aquariums, I suspect 100+ gallons as large ?
If so, the answer is yes. You don't need compressed co2 to have a good looking growing tank. I owned and maintained a 125g for a number of years without CO2. It's about balance. The right amout of light and livestock and plants.
6 Years later, I downsized to smaller tanks and use a combination of compressed CO2, "electronic CO2 -carbo Plus, and DIY co2. I have been around doing aquariums for 30 years.
Compressed CO2 and proper lighting offer superior results, but takes more effort. My compressed CO2 system is controlled by both PH and timer. So it works when needed and the lights are on. Plant growth is speedy and hence more work. You make a mistake in the high tech approach, things go bad fast.
The no co2 appraoch works and is like "slow motion" and lower maintenance and slower growth - but works fine.
Most people want instant gratification, with compressed co2 you have a head start but must watch a number or parameters.
My recommendation, invest in a compressed CO2 system and good versatile lighting, start slow on the CO2. Once you learn lighting and co2 control "You can dial in the "speed".
From my experience, most overstock fish in a early rush to sucess, leading to algae problems. Try plants first with a slow introduction of fish.
