Gal kas galėtų pasidalinti idomiu straipsniu apie akvariumų su nedideliu apšvietimu, kai naudojama paprasta savadarbė CO2 įranga (low light, co2 injected tanks) priežiūrą?

Radau nuotrupų:

Gražus vaizdelis už prieinamą kainą, paprastesnė priežiūra nei stiprus apšvietimas+CO2:
"2. If You have a tight budget, but would like to create a nice looking aquascape. Choose the Low-light High-tech method, meaning less light, less nutrients, inexpensive DIY/Yeast CO2 solutions, etc...
For this method I dose Tropica Plant Nutrient N & P + traces 1-2 times a week followed by a weekly 50% water change."

Augalai stiebiasi link paviršiaus ne dėl šviesos, o dėl CO2 trūkumo:
"For example it is believed that Hemianthus calitrichoides Cuba (HC) needs high lights to be able to grow into a foreground carpet. This isn’t true! This plant will do just fine under lower light conditions as soon as the CO2 is not a limiting nutrient. In CO2 limited systems HC like many other plants will grow upwards trying to reach over the water surface where the atmospheric CO2 is available. Many believe that plants grow towards the surface to get closer to the light source which isn’t true.
The most common reason behind plants growing like this or simply melting away is due to the limiting CO2 factor. Of course under low lights plants will grow slower but with good CO2 levels they will eventually grow into the desired aqua-scape."

Ričijos auginimo eksperimento rezultatai:

At low light:
Low CO2 = 1.1% growth
Med CO2 = 3.8% growth
High CO2 = 4.1% growth (a 272% increase over low CO2)

At medium light:
Low CO2 = 3.3% growth
Med CO2 = 9.2% growth
High CO2 = 10.3% growth (a 212% increase over low CO2)

At high light:
Low CO2 = 6.5% growth
Med CO2 = 10.5% growth
High CO2 = 14.8% growth (a 127% increase over low CO2)
