  1. alarming problem in an established pond (approx) 5000 Gallons, Located in East Tennesse, During extreme dry season, we have had several snapping turtles occupy our pond. Is there any possible prevention or way to deal with them after arrival? Thank you so much for your assistance (Added 9-19-05) —See reply.



  2. I live in Oregon and have a swimming pool that I have turned into a pond. It is quite deep, 12 feet at the deepest end and about 4 ft in the shallowest area, other than the steps. Yesterday I saw a great blue heron standing on the edge of the deep section, waiting. My fish who come readily to the surface when I appear to feed them were nowhere to be seen. In fact, still this morning I see no sign of my 20 or so koi. My question is this: how big a threat are heron to koi in a large deep pool where they really can't get in and wade around? Are these diving birds? I would hate to lose any of my beautiful fish but also can't imagine trying to cover my 30' by 30' pool/pond. I have already determined from articles that decoy heron don't work reliably. Any thoughts would be most helpful! Thank you! Laurie (Added 9-19-05) —See reply.



  3. We have a 1800-2000 gallon pond with 4 koi. We have two pumps running to a biological filter and want to replace the two pumps with one big one and also add a UV filter. We came across a calculation for figuring out how much a pump puts out per hour but cannot seem to find it now. We want to figure out what the equivelant of the two small pumps would be to give us a better idea on what size should be for the one big one. The calculation we saw was to fill a five gallon container and to time how long it takes. One pump took 45 seconds and the other took 1 minute. The two together took 27 seconds. Do you know of this calculation or a different one?

    One other question is, we have well water and the "general hardness" is extremely high. What are your thoughts on lowering the hardness to an acceptable level. (Added 9-10-05) —See reply.



  4. I live in Chicago in a condo building and would like to have an outdoor koi pond. I know, it might sound a little far fetched, but I'll explain. The condo is in an old loft building that can carry at least 100psf on the roof. I have a penthouse with roof rights. My unit is on the 9th floor, and will be building a roof deck adjacent to my unit on the roof of the 8th floor. It will be in the neighborhood of 2000 sq ft. My question really is what to do with the fish in the winter? My main goal would be to keep them in their pond year round, but how do I keep the water from freezing without spending a small fortune on heating bills? Is this possible, what kinda dollars might it cost? Might there be a product that is layed under the liner, kinda like a tile warmer in a bathroom, that would heat the water enough to keep it from freezing?To give you an idea of the size pond I am talking about, it would be probably no more than 18" deep, because that would be just under 100psf, and the diameter would be roughly 12 x 6, so maybe 550 gallons.
    If I can't keep them in the pond, I don't want to set up tanks inside every winter, so are there services that would winterize your fish for you? If so how far from the city, and at what cost? If I were to do this, and basically start fresh every year, would I have to wait the recommended 4 to 6 week period every time before introducing the fish back to its home pond? This would be such a beautiful addition to my proposed roof deck, I just need some guidance if it is to be done right. Any info you can provide me with would be much appreciated. Thank you in advance for your time. (Added 8-19-05) —See reply.



  5. i am having an impossible time with my pond. brown water and the skimmer is filled with muck 2 times a day. 4000 gallon pond with a 5,000 gal pump going to a pool type filter that then goes into a hydramax filter with a 37 watt uv light. also a 10,000 gal pump to the little giant waterfall with 2 pads and bio balls. i also have a large bubbler in the 6' end. i was adding barley extract now i have 2lbs of barley straw. i have made 8 - 1000 gallon water changes in the last 4 weeks. i have been adding 4 ounces of clay a week for 8 weeks. any suggestions?

  6. Are there any native oxygenating plants that will grow year after year in the Midwest area? I currently live in the southwest corner of Ohio and put in a pond approximately 20 x 15 feet and 4 feet deep. The local pond store only sells oxygenating plants that live for 1 year and that seems odd to me. Even if the fish eat part of them I would hope there is something that grows here native. It seems to me that while fishing in lakes and reservoirs in southern Indiana and Ohio I have seem numerous plants that resemble water grass type plants. I've even collected some Lotus seeds from a reservoir in southern Indiana that I plan to try and grow this next year. Is it really necessary to buy plants for a pond? (Added 8-11-05) —See reply.



  7. After getting quotes on a pondless waterfall installation, my wife and i decided to install one ourselves. The problem now is that I've got leaks springing up along my streambeds. It was reccomended that I use Great Stuff! foam sealant between the rocks. It is now looking like I have more foam than rocks. Any advice on products to use to seal between the rocks?

  8. I just purchased a weekend home that has a 11' x 17' x 16" deep (approx.) pond. Seems none of the average landscapers, nurseries, plumbers, etc.. can fully give me a solution to my situation: The pond is consistantly fed by a deep artisian well, constantly displacing the water & ecosystem. This makes any potential chemical treatment near impossible.

    I would like to put koi in to help keep down algae, snails & small swimming "creatures"..... (Added 7-21-05) —See reply.



  9. ...We have 6 mature gold fish ranging in size between 2 to 4” and about 3 or 4 of last years babies that are just turning gold now and probably about a dozen new babies from this spring. I know this is probably too many fish is they all grow up, so we will have to do something. We have never done a water change or added any kind of chemicals. I feed the fish only what they can eat in 2 min once to twice a day.

    1. Should I do a water change, as everything appears good? And if so how often and what about city water with chlorine in it?

    2. Should I leave the babies and see how many actually get big, or do I do something now with some of them?

    3. We introduced two new fish a couple of weeks ago; one of the small ones, but with neat markings had a white cloudy spot on its mouth after about a week in the pond. It would hide a lot and it never ate any of the food I gave the fish. I can’t find it now; would the other fish have eaten it? (Added 7-21 -05) —See reply.



  10. We recently brought some water plants at the Darien, Illinos show. All told six plants, they have multiplied by the day it seems. Now the pond is 80-90% covered.Is this a good thing or should we cut back a bit? Anticipate any response, thank you. (Added 7-21-05) —See reply.

  11. I live in northeastern Ohio. I have a homemade pond in the backyard, about 500-750 gallons. The pond has a black plastic liner. I just went outside and the plastic liner has risen up from the ground; I removed some rocks and looked under the plastic liner. There is ground water that is forcing the liner to rise. This happens several times a year and I have to use a sump pump to remove all the water from beneath the liner, then put it back in place and wait for the liner to rise again. I have contacted several landscape companies and none can give me a way to fix this problem, short of installing some sort of expensive permanent sump pump in the yard. Is there a way for me to solve this problem on my own? What about removing the plastic liner altogether? (Added 6-29-05) —See reply.

  12. ...we were wanting to know how many gallons of water we have in our pond. we have calculated and figure around 1000 but our brother in law figured 800 something so now i would just like to be sure as to who is right. our pond is a round 10 ft diameter 18 in deep with a center 4ft circle that is 3 ft deep. what is your calculation? thanks again,i appreciate your help.

  13. I have a very sick koi, he was gorgeous about 2 weeks ago, but then I noticed his tail fin looked "funny", so I neeted him to inspect more closely, yes indeed he had a problem, his scales were raised, eventually fell off and his tail is completely gone. I placed him in a bath with some medication for systemic infections for a few days and he looked much better, but his tail & scales were still missing. Last night he was swimming to the top gasping for air, so again I put him in a separate container with the medication, but I truly do not think he will make it.

    My pond is 8 x 13 ftx18" deep, 1900 gph waterfall pump and 1100 pump that I use when it is very warm for a fountain in pond. My fish include: 6 koi (1, the sick one, was about 13", 1 about 8" and the others under 4") there also is 2 comets and 6 goldfish and 1 10" plecastomous, all except Mr. Hoover, the largest are fine. The amonia is good, the ph is 8 (here in Watertown WI, I am told is about the correct ph) and no issue with nitrites or nitrates. I also have plants, though they aren't very large due to the continuous nibbling!

    My question is, am I over populated and if so, why did the largest and most beautiful (he is a butterfly koi) get ill? Are the rest of my fish suseptible to becoming ill too? What should I do to prevent this with the other fish? And if Mr. Hoover is still living when I get home today, is there anything I can do to aid him. I am relatively new to ponds, only 5 years, but this is a new and enlarged pond, previously I had only 250 gal pond with no issues.

    Another question I have is could I leave my fish outside during the winter? I have a deicer I could use, but I think I am too shallow for WI winters. Am I correct? Thanks for any answers you may have. I hope you have some advice to assist Mr. Hoover. (Added 6-29-05) —See reply.
