Well, my point is it is as much a human social issue as it is anything to do with planted tanks.
Folks think more light, or high tech is better, it's not.
Or that CO2 is "better", it can be or not.
It depends on expectations, assumptions and most importantly, goals.
The methods do not fail, people do.
Non CO2 works well
Low light CO2 works well
High light CO2 works well.
Here's 3 examples:
All examples of successful tanks.
Which is is best and easier?
Depends on who you ask.
Some view best as low work and longer term care. They would chose the non CO2 method.
Some would say the lower light CO2, they can grow whatever they chose and not spend much time trimming.
Others think more is better and might chose high light + CO2.
The last one is fine..........if you are experienced and good with dosing and CO2, heck there are folks with 5 years in that are still lousy with CO2 or dosing.
But telling a newbie to chose high light + CO2 because they like HC is irresponsible, not too mention wrong, because you can grow it with 2w/gal just fine.
Wanna argue about that? Then explain this tank which has 2w/gal and the lights are 12-14" high over a 24' deep tank:
It's not skill etc, it's wise choices and not falling into the assumption more is better.
This hobby will not grow and improve until we can help folks make fewer mistakes and bring new folks into it over the long term. So their success is important.
You have to be honest with them, tell them they do not require 4w/gal to grow HC. They need honesty and good advice, not the same old tired dogma and myths that float around and never improve success rates.
They do not need a pal that pads their feelings and tells them what they wanna hear, they need someone who'll tell them common sense advice.
Then you get respect and a real friendship:thumbsup:
We know there are several methods and each has trade offs.
What those are can be applied to helping folks succeed and increase the chances of success.
I've yet to find a single plant that **requires** more than 2 W/gal of lighting. That's 300+ species.
I've challenged folks to bring forth an example. Not one person has won this challenge to date. Common sense dictates: more light= more CO2 = more nutrients= faster rates of growth= more pruning, harder to maintain.
Algae seems more an issue of light(too much generally) and poor CO2 stability.
So less light, good focus on CO2 stability are the keys.
Nutrients are rather easy and straight forward. Then go from there with helping them. Might take a few back and forths with them to solve the issue. They might not take your advice either.
