  1. Pond water quality and feeding questions

    Water quality includes many factors besides the nitrogen parameters. Just to give one example, 5 or 6 years ago I noticed that our water was cloudy. The water department said everyone had that and it was not a problem. Then I began to get fish deaths. The most impressive were in fry. I kept the fry that appeared in waste water from my ponds. The ones I thought I might want to keep, I kept in small tubs that got 100% water changes every other day. The rest went into a large stock tank with some duckweed on the top of the water which got no water changes. I observed regular deaths and little growth among the fry with the large water changes, while those in the stock tank thrived as expected. I also noted that all of the adult fish that died had also experienced a recent large water change. Enough people complained to the state about the bad water, that they tested it and found TTHMs (total trihalomethanes) far above allowable levels. I started storing the water I used for water changes with carbon filtration to remove these organic contaminants. I do roughly 10% daily water changes with stored water which keeps the fish happy. The fish deaths in your situation probably came from disease/parasites. Healthy fish carry parasites and pathogens to which they have developed immunity. Typically all of the fish in a pond will carry the same parasites and pathogens and stay healthy. However, if healthy fish from this pond are mixed with healthy fish from another pond the fish will not have immunity to the pathogens carried by the strangers. Does the pond have aeration? I'll repeat an earlier recommendation. "I recommend they join the local Koi Club Check out this one. Koi people love to give advice." An experienced ponder who actually sees the pond and can talk to the owner can quickly identify problems.
  2. We lost all our four year old fish. Snails to blame?

    Those were beautiful fish. Losing all of the fish usually indicates toxic water. I notice pebbles in the bottom of the tank. If you go to any pond forum, you will see people complaining that their fish are dying after enjoying two years of good health. The experienced people always ask the same question-- "Do you have stones in the bottom of the pond?" The answer is always yes. The spaces between the stones collect debris that rots. The decomposition process uses up oxygen, and may release toxic gases. Read all of Walstad's book. It's loaded with sound information.

    Welcome to Kokos! Please show us some pictures of your fish.
  4. Pond water quality and feeding questions

    What are those things in the last picture? How deep is the pond? Is the net above the water or on the surface? I use this food (from Drs Foster and Smith) and have for years. It grows big goldfish. The small koi pellets have just the right size for small to medium goldfish. Big goldfish easily consume the medium koi pellets. The sale price is excellent. I going to order some more before the sale ends. Don't get pond fish food from the pet store. It costs much more than the high quality food and contains mostly cereal. I'd start out feeding a teaspoon of food twice a day. I suspect the food you saw floating around wasn't more than they could eat, but rather the huge pond surface made it too hard for the fish to find all of the food. I wouldn't worry about the trace amounts of ammonia, nitrite, nitrate unless they increase. They might consider putting some water lilies in that pond. The fish love to have something to hide under.

  7. Will hose chlorine kill good bacteria?

    It depends. If the pond was empty and they filled it from the hose, then they will have to add some dechlor or aerate the pond for a week or so to drive off the chlorine. Many koi people say, as a rule of thumb, that you can change up to 10% of the water without adding declor. The effect of chlorine on the nitrifiers of an established filter gets greatly exaggerated. Most pond people clean their filter medium with the hose, with no loss of nitrification. Even if they lose a lot of nitrifiers, a few small koi in a 5000 gallon pond will not raise the ammonia level in the pond significantly before the nitrifiers recover. I recommend they join the local Koi Club Check out this one. Koi people love to give advice.

    Higher temperatures do speed up metabolism and result in rapid growth, maturity, and aging. Goldfish are labeled as "cold water fish" as opposed to tropical fish, meaning they don't need a heated aquarium. In fact goldfish have one of the widest ranges of temperature tolerance known -- from just above freezing to 41C/106F. They thrive outdoors in tropical waters and under ice in cold winter lakes/ponds. Native goldfish can be found in the Southern Yangtze River, in an area with a climate similar to FL. http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0059571 I thought I had read all of the myths about goldfish, but the idea that higher (than room temperature) temperatures benefit the immune system is a new one to me.
  9. Hello everyone. I'm Kovi

    Welcome Kovi! Please read our guidelines for healthy goldfish.
  10. Please read our guidelines for healthy goldfish. Pay attention to the information on water changes. Acceptable levels are zero ammonia, zero nitrite, and no more than 20ppm nitrate. If the nitrate goes higher the pH will drop. API doesn't give the active ingredient in pH up, but most people who use it think it is baking soda. I can buy 5 pounds of baking soda for less than $4, and if I had to use it in the tank, one purchase would give me more than a lifetime's supply.
  11. Use baking soda (sodium bicarbonate) . Draw a known volume of tap water into a bucket. For example, 20 liters. Read and record the pH. Add a known volume of baking soda -- for example 1/4 teaspoon. Record how much you added. Give it a few minutes to completely dissolve, then read and record the pH. Repeat this procedure (adding baking soda and reading the pH) until you get the desired pH. Most people like pH 7.5. Add up the total amount of baking soda you have added. That's how much baking soda you will need to add to each 20 liters of tap water for your water changes. You could multiply that by 12 to determine how much you would have to add to your full tank. However, you don't want don't want to add to add baking soda to the tank all at once since you can shock the fish by rapidly changing the pH. I suggest you add the amount of baking soda that you needed for 20 liters of tap water to the fish tank daily until the pH reaches your goal. After that, add the baking soda only to your new water when you do a water change. How often do you change water and how much do you change each time?

    Veiltails lack vigor and tend to bottom sit because of the tail weight. I have seen breeders brag about a crop of veiltails that were still swimming at 3 years of age. These fish present a challenge to highly experienced goldfish keepers. Many inexperienced people call any fancy goldfish with a very long tail a "veiltail". While veiltails have long fins, they have tails that are are all one length -- like a veil. Most often the long-finned goldfish has a ribbon tail.
  13. Tank set up - too many options!

    Please read our guidelines for healthy goldfish. We recommend at least 76 liters per goldfish. Also, goldfish like the companionship of other goldfish, so you should consider a tank large enough for at least two goldfish.
  14. DIY Sponge Filter

    Watch this. No, don't use a kitchen sponge. Even if it doesn't have soap in it, it won't provide the water flow you need. Sponge filters are so cheap that DIY doesn't save much money and may even cost more.

    I'd keep the HOB in the tank for at least a month total.
