    You are right!

    I would guess your pond volume to be just under 3000 gallons depending on whether your walls are sloped, or your corners are rounded and the depth of your shelfs. You need a pump that moves a minimum of 1500 gallons per hour.

    The pond is about 3000 gallons. I don't know the gallonage is for the pump running in it, but it seems to be doing the job. They have been in there and doing fine for years, till this spring. After that bout of whatever it was they are doing great now. There are about a half million babies to prove it! I did several water changes and salted them down and after the water change they perked back up. Thanks for your help, Les

    All's well! Thanks for the input. I feel a bit better about my setup now too! Les

    good idea, The closest Large Pet store is over an hour away, but I will make it a point to take a sample next time I go that way. Thanks,, Les

    If you still have string algae after 2 PP treatments, the PP was not dosed properly. If the string algae was not severely set back, any parasites were not either.

    The unusually cold, long winter (by Florida standards) has now been followed by early heat waves with highs of over 90F. In a pond as shallow as yours, the temperature swings will impact the koi. My pond (6-feet deep and shaded) was very slow to reach 70F this year, but then jumped to 76F in just a few days. If your pond is in full sun, it would not surprise me if your fish went from around 68F to over 80F in a period of 4 days or less.

    Thanks Mike, It was a miserable winter for sure. In spite of the spring temperature fluctuations I have a little to no sever affects [so far]. I've never had string algae before so it is really bugging me. I might drain it and scrub it down. I wish koi ate it! Now it is ladden with eggs. All the same I need to get it out of there. Thanks , Les

    Heavy growth of string algae leads to oxygen deprived water overnight due to respiration of CO2 and consumption of O2 in the water column. 250 gph pump for such a large volume of water is barely enough to put a dent in a small fish population, which may help to explain why the string algae is overwhelming you as it is consuming far more nitrogenous waste than your biofilter.

    Give us some more information on the water such as ph, kh, gh, temperature, ammonia, nitrite, nitrate, phosphate. All of these factors play a major role in the way your fish will behave and their general health.

    Your pond should contain roughly 5000gallons of water according to the dimensions you gave. You should be turning over your pond at a rate of no less than 2500gph, preferably 5000gph, through an effective biofilter. What are you using for mechanical and biofiltration as things stand?
    Thanks Larry, The treatment was pretty low as I don't trust PP very much for that reason you gave that it can burn gills in a hurry. But as you may have read in my other reply, they are fine today and spawned. With cleaner water in there now at last check they seem like new fish!! I am going to try to work on getting a bigger pump, that is excellent advice.
    I have to work on getting a test kit. Fixed income limits me, but my fish deserve better! I appreciate your advice, Thanks again. Les

    You didn't mention filtration, just a pump. Do you have any filtration? Are there rocks in the bottom? Is there muck in the bottom?

    You can get test kits at any pet store, although they are usually the strips and not very accurate. You can order test kits on line and they are relatively inexpensive. A kit with the minimum, pH, ammonia and Nitrite is about $16.

    How many fish and what size do you have in the pond?

    I have a half 55 gallon drum with media in it for filtration. It has always done a good job. I do not have the best of systems out there, all homemade and for the most part, very effective and reliable. No rocks , just a clean bottom. I will do my best to get a test kit. The fish deserve it don't they.
    Like I had said yesterday, I treated with a low to moderate amount of PP. Like magic today the were swimming and spawning!! I collected all the eggs I could get and put them in waiting tanks. Then I ran clean water for a half hour to get rid of the stench. Now they are swimming normally and looking like nothing was wrong.
    There are about 10 12' to 18" long-fin koi in that pond. Over stocked I know , but I have no other ponds to put them in yet. I have the liners but no way to dig a pond. I might rent a tractor and get that done.
    Thanks for the input. Les
