serious green water "needs fix"

Photosynthesis in plants and algae produces oxygen. Respiration in animals and fish uses it up and produces carbon dioxide.

reading my post now, that is what I was trying to get out I guess I posted the direct opposite of what was supposed to be implied, but with that being said..

- If the algae doesn't produce enough oxygen in the water during the day it is possible for your oxygen content to deplete during the night. The dying organic matter and algae do use up oxygen at night along with fish. If I remember that correctly, its more relevent for a pond and algae blooms but I would assume there is some relevence to aquarium life. I guess that's where your Skimmer would come in to remove the dead oragnic matter.

You were half right. At night the system reverses and oxygen is used up which can lead to the die off of phytoplankton and the consumption of even more oxygen as the algae decays.

Thanks for the clarfication and correct to my post. I'm going to have to read and refresh my biology.

exactly. u beet me to it... apparently u type alot quicker than i!

So the green algae happened after a water change. What kind of water are you using? If its tap water, whats the TDS?
If RO/DI then no problems.

i go down to the 24hr water thing and plunk my coins in for the 7 stage ro uv blah bla blah.... filtered water. have no tds meter so really no idea how well the water actually is. i tell myself the water "should" be good?

Its all you can hope for, water should be good.
As another poster said, UV would get rid of the algae. But it is feeding off of nutrients in your water, so you must control those first.

which again, i cant find? i laid right off on the feedings for months now and dont have huge pile of crap laying around? all in all the tank is pretty clean. the system is almost a year old so ive had one algae after another but this is the only one i havnt been able to control. i used to go all day then turn the lights on after work (so including natural light and my lights there was light for about 15+ hrs a day. also have 1 old bulb (who knows how big a deal that is?)
