High-Light/High-Tech vs Low-Tech comparisons:
I remember researching plant needs, and I think like a lot of us do I inevitably came across a foreign concept known as "Co2 Injection" or sometimes "Co2 supplementation". When you come to the hobby without ever having found your green thumb as I did, then find a metric ton of data, articles, best-guesses, and DIY ideas concerning light requirements & requirements of Co2 in the planted tank it often becomes a matter of trying to understand the needs of plants (with little experience) and filtering the outdated and sometimes often wrong or confusing information you can find skimming over one forum topic to another where there's rarely an exact answer - more often, the best guess is the answer we're left with and these guesses often leave a feeling of unfulfilled longing after hours of research and finding we're barely any closer to a definitive answer then when we began a cup of coffee and three Advil's ago. While I can't possibly cover enough of these misconceptions, I can go over a few.
Question: Does the addition of Co2 mean I won't be scrubbing hardscape/decorations and my glass as often?
Answer: Nope, and you won't get out of maintenance duty this way either, slacker. A mostly algae-free tank can be achieved with or without added Co2, and at the same time a completely mucked up tank you have to spend 30 minutes scraping glass just to see a fish can also be achieved with or without Co2. What determines algae is the balance of nutrients, lighting, and Co2. There are other factors such as the flow of water, placement of plants and hardscape, your cleaning habits and frequency of water changes and filter maintenance. Long story short, additional Co2 will not provide you with a crystal clear tank, lush plant growth, and zero algae without some level of care - more importantly, an understanding of cause and effect in a planted tank when it comes to algae and deficiency.
Question: Do High-Light Co2 injected tanks have less algae than other tanks considered Low-Tech?
Answer: Um... absolutely not! The exact opposite is most often true as a matter of fact, and the reasoning is actually pretty simple. The rate of growth seen in a High-Tech tank is often referred to as being 10 times faster than a Low-Tech tank. Plants and algae are photosynthesizing at a much faster rate to achieve a rate of growth that is said to be 10 times faster than other tanks. When something is happening that much faster the margin where error is allowed is narrower. If you neglect a water changes on a High-Tech tank bing E.I. Dosed for two weeks you can rest assured algae will begin to grow at a rate 10 (or more) times faster than a Low-Tech tank, often having much more algae in a shorter span of time.
Let me put it another way. If I want completely algae free glass on a low-tech tank every day of the week it's normally a matter of a quick scrubbing during a water change to prevent the algae from latching onto the glass long enough to grow and become visible. It takes as long as a water change, and doesn't normally become visible until 2 weeks. Sometimes less, sometimes more time depending.
In a High-tech tank the glass needs to be scraped weekly, or sooner, to achieve the same clear perfection. Unlike the brown algae we usually see covering the glass in a tank with less light, often much easier to clean, a tank with stronger lighting grows more resilient algae that are harder to clean from the glass. Once that glass is sparkling you can often see bits of algae trying to grow over hardscape, still keeping in mind the growth rate is 10 times faster.
Algae is a nuisance that all tanks see. It's inevitable. However, a tank with stronger lighting grows plants AND also algae much faster. While you may not have a higher load of algae when comparing the two set ups, it becomes easier to spot than the slowed growth of low-light.
Question: if Co2 is so beneficial to overall health, then most people would have a pressurized system of injection, wouldn't they?
Answer: I walked into a Petco a few weeks ago and was looking at some fish gear and saw they now has a section oriented to lighting + small Co2 injection systems using disposable Co2 cartridges. These items have been sold in this particular store for quite some time, but the Co2 systems have always been shelved with miscellaneous junk items like airstones, suction cup betta leaves, and cheesy backgrounds. I took note of this placement because it told me two things
More people are aware of the relationship between injection and strong lighting, and cheaper systems that do the same as an expensive system are being marketed toward beginners as not only a way to cash grab, but because there's enough free marketing found on all the forums that the curiosity of the consumer has been peaked, but only if the price is affordable.
Everyone doesn't use a system because in the most blunt way I can think of, it's just not needed. Not needed, that is, unless you want to grow a tank towards the marketed ideal of modern Aquascapes with lush carpets and brilliantly colored plants. I've read pressurized systems used to cost a small fortune of hundreds and hundreds of dollars, and for those of us who still have sanity in this hobby that much money isn't practical to sink into a tank. More people than we realize have pressurized systems because the cost has dropped from three to even five hundred dollars to a disposable cartridge system for less than a hundred.
When I incorporated an injection system into a tank I'm searched for the best deals. Too much time wasted and more reading than I cared for, I finally came up with an affordable system and can piece together a complete Co2 system for about $130, which is ran on a timer with solenoid, precise and accurate BPS and pressure, dependable with cheap refills. It's a set up for tanks 40 gallons or under and cost the same whether you're running a 10 gallon or 4 gallon if you exclude frequency of refills.
I think more people don't go buy a system because it's a nightmare trying to find a unit that works and is affordable. If you look into a regulator you can spend $60-$300 just like that. It's because the price of a system is either cheap or expensive that people tend to not want to sink their hard-earned cash into a system they have little knowledge about, where the market is either a very Chinese cheap side to several hundreds of dollars for just one part, and there's little way you can tell the quality and ease of function when it compares to price.
Question: Co2 injection systems have lush, beautiful growth, so do I need Co2 if I want to imitate that growth?
Answer: Yes - well... kinda?
Co2 and high light is the easiest and fastest way to achieve dense plant growth, good health, and virtually all common styles of aquascaping. It becomes a possibility if you manage the tank well that you can recreate a professional styled look with great health and few problems.
On the flip side of the coin, with a bit of research, time, understanding and maybe a few questions directed towards the right person you'll realize that if you want to recreate most modern Aquascapes and their plants you likely will need to invest in a Co2 system, but you have to think of it in a different way. Lush, densely planted aquariums have been around before a method of Co2 injection was conceived.
Don't believe me? Well... the densely planted style of tank known as a "Dutch Aquascape" is one of the oldest styles of planted tank in the hobby, finding it's roots in the Hobby some time around a century ago. Yes, I wrote that correct. I think we can all sleep easy knowing if TakashI Amano is to be credited for bringing Co2 systems to the hobby decades ago then there is no way "Dutch Aquascapers" had access to pressurized systems.
So how? The answer is simple - plant selection, understanding of growth habits and care, and time. When aquascaping in low-light and no Co2 in these three keystones that will bring your vision to reality.
As for example: Low-Tech/Low-Light, No fertilization dosing, siesta period, or liquid excel dosing of any kind. Just time... plant selection, a bit of luck, and patience. It's certainly no Dutch tank, but a low-tech nature design, which is also a concept credited to the father of Co2 injection, TakashI Amano, but lacking in all ways that very same contribution of bubbly gasses ran into a fish tank. R.I.P. Mr. Amano.
