If you use a 150 gallon or even 75 gallon
stock tank
you can use that learning pond as a plant
filter when you do your big pond.
Or leave as a pretty water feature.
Or use it as an isolation tank for future
fish buys.
We have the 150 gallon as the header pond
in our waterfall. Water comes in at the bottom
and out thru drilled holes with bits of pipe in them at the top.
