Help in Maintaining Aquariums/Fishes...

The greenish water color means suspended algae and one way to get rid of it is to first clean the gravel by syphoning the gravel during a 25 to 30% water change (this will get rid of lots of food that the algae needs to grow. Next comes complete darkness for 3 days (algae needs light to live) and higher plants can take 3 days darkness0. If you do not already have them then get plenty of true and healthy aquatic plants (they will compete with he algae for the available food and usually will out compete them. This does not mean one or two small plants but rather enough so that you cannot see the back of the tank through the front. The plants will also help to filter the water but you still need to do regular partial water changes. I recommend a 20 to 30% water change each week with water that has the chlorine and chloramine removed from it.

okay could be bacteria, and you have a good filtration system? could be temperature of the water, try this link: http://www.petlibrary.com/goldfish/fishcare.htm

I would have a hard time seeing them in a big colourful aquarium. I know it seems boring, but when I had fish, I'd just maintain them in a clear bowl, with a rock or two at the ottom. It made it easier for me to see them, when I needed to clean the bowl out.

Hi Muelitz-I don't have an aquarium but do have a pond-although it started out as a nice clean pond but my ex-hubby didn't clean it out so now I have what I call my 'nature pond where I have frogs newts and toads there and every year the frogs come back and mate there as frogs always mate where they were either born or live-I find it really relaxing and peaceful to watch-although aquariums and fish are also a therapuetic way of relaxing if you have them in your house and like you I would hate to have clean it out because of the slime etc-your friend littleowl
