My husband and I are having a big discussion
over this one!
We are building a KOI Pond in our yard
and it will be about 3,000 to 3,500 gallons. In order to know
exactly what size it is we want to use a water meter while
filling it. Our water pressure is a little low so he wants
to use two water hoses connected to different water faucets.
Can we use 2 hoses at the same time with a meter, maybe using
a Y connection? Will this be an accurate reading or will the
Y change the accuracy of the meter?
Water meters measure flow, and most of them are mechanical,
the water flow spinning a small rotor inside the meter. If you
hook up both hoses to the meter via a y-connector, it should
still be accurate, but it would be worth your while to check
it, just to be sure. Get a big bucket or tank and manually,
with a 1-gallon container, dump as many gallons into it as it
will hold and record the volume. Mark the inside of the container
with some sort of indelible marker and dump it out. Hook up
your hoses and meter, fill the container to the line and compare
the meter reading with what you know to be the true volume.
Fill your pond and do the math.
You can also measure pond volume
with the salt equation, which can
be found in the FAQ section on our website. (www.mpks.org)
You'll need an accurate salt test kit or meter, a set of scales
and some patience. The formula is: Total gallonage= lbs salt
added x120/difference between salt concentration before and
after salt addition.
Get your pond full to capacity and
get the filters and falls running. Measure salt concentration,
then add a known weight of salt. Wait several hours for the
salt to dissolve and distribute evenly throughout your system
and measure the salt concentration again. Do the math.
