hello my names matt im from louisiana and im currently in the process of building a swamp style/theme pond. mosquitoes is how this all started a few months back our pool pump went out so nbd wel will get a new one when it warms back up. well after about a month of hard rain all chemicals were washed out of the pool. and soon after mosquitoes started laying eggs and growing to adulthood rather than keep dumping chemicals in we threw a few gold fish in to eat the larva of the flys thoose 3 live and grew crazy fast and we threw a few more. Well now its time to drain the pool and clean up so where are theese now very big pretty fish to go? well ill build a pond so thats where im at. Its in my garden behind my pool right up against my cypress tree just like in the swamp. and thats as far as i got questions advice all welcome and askin for advice also. whats the best liner for the price how do i seal the side of my tree to now suck my pond dry or put to much tree oil etc n my pond im lookin for a spray or clear coat? the pond is 10 ft by 8 ft and from 2 ft to 4 at its deepest.
