While the advice you have received is sound, the small changes of a couple gallons of water each day for a few days achieves another goal. Even after rincing, the initial water in your aquarium has chemical residue from the objects you have chosen to decorate. I would even guess if you open the lid you can smell chemicals. As one of your responders suggested, it can do no harm to change a little water each day until the water clears. Your water will clear, as predicted, either way. Now for your next suggestion: Read the links you have received and you will see the words "do not overfeed". These words have been posted for as long as there have been forums. Be careful!! The most commom interpretation is to conclude: "OK, I'll just feed once or twice a day." This conclusion will start you down the path of failure because you will instinctively choose an amount (a pinch) that you believe will last the fish all day. When you receive your first fish, do not feed for a couple of days and then choose an amount that seems to just tease the fish but feed often!! 4 or 5 fish should be fed no more than 1 average sized flake (broken up). However, you can feed many times per day!! Even 10 times. Maybe a few times before work or school and then again many times when you get home. Never a pinch at a time!! The most common answer (on this forum) to problems with your aquarium will sound like, "Don't overfeed your fish." or "You are overfeeding your fish.". The truth is you are not overfeeding. You are polluting your aquarium. So, go back to my original recommendation. Feed too little, too often! You don't have fish yet so there is no problem, but be careful interpreting "Don't over feed". Good Luck!! Bob
