Green Water and Undergravel Filter, what is the cure?

The friendliest place on the web for anyone with an interest in aquariums or fish keeping!

Well I am certainly not a Plant Biologist ;-) I just like fish. For what its worth, i have a book, "Aquarium Plants Manual" published by Barrons, and written by Ines Scheurman (bought at PetClub). This book is translated from German.

On page 14 is a diagram of a plant biological cycle, the caption says: "interchange of oxygen and carbon dioxide between fish and plant. By Day: The fish and the plant inhale oxygen (O2) and exhale carbon dioxide (CO2). During photosynthesis the plant takes in CO2 and produces O2." on page 15 another similar diagram and this caption "By Night: The fish and the plant consume oxygen (O2) and produce carbon dioxide (Co2) photosynthesis is not possible in the dark"

I looked about on the internet for some similar information, but did not find it. I myself am not in a position to say whether that information is accurate per se. I place it here so all can interpret it for themselves ;-)

Of course, the real point here, Is that I too have one of these nasty Green Water Blooms. I am pretty sure I kicked it off when i pulled out my UGF last week. I am using a product called ALGONE to try and help get thing balanced again. Does anyone have any experience using this?

As for clearing the Algae. Since I don't want to use chemicals, and can't afford a diatom filter or a UV sterilizer atm. It seems the advice here is to get my parameters back in balance (which algone should help with) and wait it out... which should take a week to a month?
 
A week, a month, two months, who knows :? Hopefully about 3 weeks, but that will seem like an eternity! Keep the faith! :D
 
UV, UV, UV. Its so easy, and they don't cost that much. Look at Jebo models if price is a big concern, but I am VERY happy with my Coral Life Turbo Twist. I think they should be a basic part in a lot more aquariums.

Remember what we are often taught early in school is not always exactly true. We are taught general concepts and ideas. However respiration in plants should typically be covered in highschool biology and I would seriously question a "college" or "university" if general botany or biology for that mater fails to point this out.

What exactly are you guys even debating? For fish keeping all you have to know is sunlight and CO2 need to go in, and O2 comes out. I could get you the actual equation if you want, but its not going to matter in terms of fish care, so why bother?
 
Also, plants and algae don't consume oxygen, they consume CO2 and release oxygen into the water... therefore the plants actually help to better oxygenate the water.
That's true only with light!!! Plants need light to consume CO2 and produce oxigen. Without light, they will decrease oxigen level in your tank water.
