    I am wondering how many goldfish or Reds can be added to a pond that is 16' X 8' X 19" deep? It has a submerged pump and fountain (Pondmaster 1500), some water plants, and is a pond made with a flexible liner over carpet and sand.....(No waterfall or skimmer yet.)

    around 1400 gallons. Depends on who you ask, some say 10 gallons per goldfish, so that would be 140 fish.

    You could probably put as many Goldies in there as you would want lol, I see you have the Pondmaster 1500 kit like I got for my smaller 400 gallon pond, it has been working well so far :)

    There is no concrete answer to this question. It depends on several things. How often are you willing to clean the filter? How much water changing do you wanna do? Do you plan to feed the fish? Etc. Personally I find that 50 gallons per fish is a good balance for me.

    I have to agree that it depends ... with AVERAGE filtration and plants, I am in the 50 gallons of water, per goldfish... So if the pond is 1400 gallons, that would be 28 ADULTS who should do okay ... Exept for the tiny little thing that goldfish multiply faster than rabbits ... Hubby did a 2000 gallon pond install for a client ... Moved their 10 goldfish into the new pond mid May ... I am guessing there were a couple thousand babies, but a lot got backflushed out of the filter ... Guessing they still have 300-500 fish in total at the moment ... My advice is to buy 5-10 pretty babies that you really like, watch them grow, and next year, be ready to rehome HUNDREDS;-)

    There is no one answer for your question. It's like asking how many people can live on 1 acre of land. You could build an apartment building and fit 50 people on it, or a single family of 4. And like one poster above said, the fish will multiply every season. Best that you chose a few fish you like and add every season. That's what's happening with my pond. I don't go out looking for fish to buy, but sometimes I see one who's so good looking I have to buy him!

    I keep population under control by not feeding heavy, esp if I see them chasing, they get hungry and snack on their eggs, eat them right up. They get fed 2-3 times a week, sometimes just once a week if I see a lot of chasing.

    Thanks all for the advice!
    I know this is off subject, but I now realize that I need to carefully re-calculate the volume and GPH in this pond.....It is difficult because of the center island and underwater shelves that are around about half of the pond. Does anyone have a clear idea about how to do this?
    Length= 16 '
    Width=8'
    Somewhat kIdney shaped
    Center "island area" that is 3.5'
    Two deeper areas are each 19" (each about 2' diameter)
    HELP! ;)

    Yes I have a clear idea, but it isn't simple. Slice the pond in horizontal layers with each layer say 1" deep. Then lay a 1" grid over the top of each layer and count the number of squares that fall in the water. Guess at partial squares, less than 1/2 get tossed, more than half are counted as 1 (if you find any that are exactly 1/2 you are too anal for 1" squares and need to use smaller and smaller squares until you say Uncle).

    After you do this for each layer you add total all the squares in water and that total is cubic inches which can be converted to gals with many online calculators.

    As I alluded to, 1" square gives you a certain precision, 1/2" squares gives more precision. Smaller the square the higher the precision. So depends on how far you want to go. Something like a 1' square is more than good enough for most people and pretty easy.

    I do it in software so it's simple to get very high precision.

    Of course that often all goes out the window when the digging starts. Ponds on paper are often not the same in dirt.

    Not enough info to work with, but a simple rectangle, 16' x 8' x 1.5' works out to a bit better than 1400 gallons ... if you cut off the corners of the rectangle, make a dent in a side for a kidney shape, the volume you are losing MAY be made up for with the island area. Depending on the size of the center island, you are likely still around 1400 gallons give or take a bit.

    :confused: Wouldn't the island subtract from the water volume? I think half your estimate would be closer, probably less than that!

    As previously noted, split the pond into easy to figure sections and then add them together. LxWxDx7.5=gallons
