Answer 1

You have probably fed to much and your tank hasn't the ability to deal with the excess food. Change 25% of the water today and starve your fish for three days to avoid sickness from polluted water.
The stuff that lives on your rocks is essential in keeping your tank healthy. Beneficial bacteria digests fish waste (ammonia) and converts it into nitrites. Other bacteria converts nitrites into less harmful nitrates. This cycle tanks time to develop and until it does cloudy water, bad smells and sick fish can occur. Be a bit patient and it will develop. Feed a lot less food, and change 25% of the water weekly (use a gravel vacuum) and make sure the temp of the new water is the same as the tank. You don't want to destroy too many of the beneficial bacteria when you do a water change and changing too much water or having it at the wrong temp stresses them. Also, your filter media has a lot of the bacteria growing on it. Don't change it too often (and never at the same time as a water change). When it start becoming clogged, rinse it out in cool tap water. Only change it when rinsing no longer is effective.
I would also suggest adding some freshwater aquarium salt (one tablespoon for every 5 gallons). It will help avoid sickness in your tank.

Fish Tank Smells

Answer 3

I have a 135 gallon fish tank with all sorts of goldfish in it. The problem with koi and goldfish is that they produce a lot more waste than other fish which causes the water to "turn" on you. When you fill a tank with "new" water you need to condition it with a solution at the pet store. Aquarium salt works good too, even for freshwater fish. The solution and the salt will produce good bacteria that will help get rid of the waste that the fish are producing. A good rule of thumb once you've got your water right, is to do a 25% water change once a week. It will take out some of the dirty water but still leave enough of the good bacteria in. I usually do my water change when I vacuum the gravel. Good Luck! I hope this helps.

Answer 4

I have a 75 gallon with 9" fancy goldfish. I would suggest stepping up the water changes. Not big ones just 15-25 gallons at a time. Try doing a small one every 4-6 days. It sounds like you had a bacterial bloom(white cloud) then an algae bloom (Green cloud)- chances are that bacteria and algae sucked up a lot of the oxygen in the water and now it is dieing. This will cause your water parameters to freak out, your ammonia to spike and a relatively stinky tank.

Is this a relatively new set-up?

The water changes should balance things out eventually. I normally change 25% of my water weekly. Look into getting a Python for your tank- it makes those weekly water changes a breeze.

Algae eaters don't normally do well with Koi. They will suck the slime coat off your fish. This will leave them susceptible to disease and parasites.

Answer 5

Your kidding, right?
It isn't unusual for fish tanks to smell. All fish have oily, stinky skin which will stink up the water. Even with cleaner fish, your tank will smell. Its natural, and if you have a good tight hood, the stink shouldnt be a problem.
Also, keeping a fish tank clean is fairly easy. Get a long plastic tube (Look in the fish section at the pet store) If you need to clean up a bit of forgotten food, place the tube a bit over the mess, andcovering the other end with your thumb to no water gets in. When you are over the mess, release your thumb for a second. When the mess is cleaned, replace your thumb. dispose of the mess in a sink.
Koi fish like open ponds. Why not take a bit of money ane get a big pnd thing at zamzows?

Answer 6

Heating a tank consistently is important for the health of your fish.

Steps
Be prepared for your heater to fail. One common problem is that the on/off switch gets stuck, leaving the heater on or off permanently. As a result, the water can get very hot or very cold, making the tank an intolerable environment for your fish.
Place two small heaters parallel to one another in the tank. That way if one fails, the consequences from heater failure won't be as disastrous, especially in the winter.
Choose between a traditional heater that hangs on the side or a submersible one. The submersible is the better choice since it can be put at the bottom of the tank, allowing the heat to rise and therefore be distributed more evenly.
Choose a heater of about 2-½ watts per gallon if the temperature in the room where the tank will be won't fluctuate more than 10 degrees either way. If it will fluctuate more than that, go with 5 watts per gallon.
Get a thermometer for your tank. The regular bulb thermometer either floats in the tank or hangs from the side and is sometimes hard to read. The other type is an LCD strip that adheres to the outside of the tank. Both types are somewhat unreliable and your best bet is to use both together.
Tips & Warnings
Minimize potential problems by avoiding heaters larger than the optimal size of your tank.
Unplug your heater whenever you work on your aquarium. If you run the heater out of the water, the glass will most likely shatter.

Answer 7

First you need a "hang on" power filter system......You can buy them at pet stores and Walmart. Get one for the size of your tank. Next you need a syphon to clean the gravel. You dont have to take out all the water, take out half. Scrub the glass with a plain clean scrubber pad. When you add the water back in, add start right or something similar to the water to take out chlorine etc........
Don't feed the fish according to the directions............Fish will eat all day long............Feed like once a day.........they can only eat so much in 20 mins. or so. The rest falls to the bottom and that is why the tank gets dirty so fast.

Answer 8

How big are the koi?
Koi don't really belong in a tank, they get HUGE.
You also need filters that move 75 gallons per hour at least.
What filter do you have on the tank?
How deep is the gravel and do you vacuum it?
How often do you do partial water changes?
What you feed them, how much, & how often?

Answer 9

Change the water. Don't just use tap water, you have to purify the water first with some sort of liquid. That liquid should be in most pet stores, go to the pet store and ask them about it.

You need to CHANGE the water. Pour the water currently in your tank out and add in new purifed water.

Answer 10

i don't have a fish tank but it seems like you should clean it out. Take out all your fish and clean the tank and everything with water (no soap, at least that's what i'm told). Even though you have fish that clean the glass the tank can still get dirty.
