Pea gravel or stone with no points will out perform the sand which holds more nutrients and I guess you have a bottom draw since it is a liner to aerate or filter away nutrients as the liner removes the resourses from the earth to balance the pond and the growth of the fish and other tennants I refer to them as tennants for the reason that their natural resources that were left to them from the past were altered without ----------- Who can say at the alarming rate that our potable supply is tainted. This Forum in the year 2040 will be disscusing the proper way to install a liner and how to consrtuct a dome to repel the elements and to purify water for the tennants not to much fodder there Bob.
