LOL
I hope it works for you, if not we'll have to think of something else.
BTW we are talking about green water that when you take a cup full of it the water is green, not like ornaments and what not are covered in algae right?
heres from what that tropical resource website says:
QUOTE
4. Green water...algae bloom. This is the most common problem if the cloudy situation extends beyond 10-14 days. Note that "green water" is not always green in appearance! Since green water is the most common problem and the most difficult to solve the answer needs to reflect several options. The situation that causes GW (Green Water) is usually a combination of high nitrates, phosphates, and mixed in some ammonia/ammonium. Substrate disturbance is usually the culprit. Water changes alone will usually not rid a tank of GW. Nutrients can be reduced very low in GW and fairly quickly by the GW algaes, but they can scavenge other nutrients...iron and trace elements. So, it's very common for the GW to solve the situation that causes it to begin with, but that won't eliminate the GW. Five methods exist to eliminate GW. Blackout, Diatom Filtering, UV Sterilization, Live Daphnia, and Chemical algaecides/flocculents. The first four cause no harm to fish, the fifth one does.
Method No. 1: The blackout method. Turn off CO2 and add an airstone if available. Your fish and plants will be fine during this short period of time. When doing a blackout follow this procedure exactly.
Day one.
1. Feed your fish. Wait one hour, then do a 50% water change.
2. Cover the tank completely with towels, blankets, or garbage bags so that no light whatsoever gets into the tank...all sides and top must be covered.
Day two.
3. Leave the tank alone...completely alone. Do not change any water, do not feed your fish, and do not even peek to see if the green water is going away during the blackout period. The tank must have complete darkness and no feedings during the blackout period.
Day three.
3. Leave the tank alone...completely alone. Do not change any water, do not feed your fish, and do not even peek to see if the green water is going away during the blackout period. The tank must have complete darkness and no feedings during the blackout period.
Day four.
3. Leave the tank alone...completely alone. Do not change any water, do not feed your fish, and do not even peek to see if the green water is going away during the blackout period. The tank must have complete darkness and no feedings during the blackout period.
Day five.
4. At the end of the blackout period do another 50% water change and lightly feed your fish again. Also address any nutrient deficiencies you may have at this time. Remove the airstone and restart your CO2 injection if using such.
Seven days after day five.
5. Do another 50% water change one week later, then resume you normal water changing routine thereafter.
Were (you) are doing a variation on that...hopefully it does work and your green water will be gone.
