I had a 10 gallon tank for a while and i upgraded to a 30 gallon tank. So im aware of all the fish care. How ever this tank was pretty clear for first week i say then got really cloudy and just seems to keep going. Ive tried water changes like im suppost to, and ive even went as far as to add some clear water in hopes to try to clear some to all of it up. Its starting to have an odor and i can smell it when i walk into the room. Yes i know it takes about 3 weeks for it to get over the new tank stuff. But can this be a lack of filtering power? or should i drain the water way more then 20-25% in hopes to try and balance out the problem?
