what is the best way to build a pond in a back yard? i've heard to use bricks and line it with pond liner, or use kiddy pools, or use preformed. what would be the best way and most cost effective?
guppy said:temp. monitors, ammonia and nitrate/nitrite monitors, O2 level alerts, a 1200g premixing vat,,, everthing you can think of. It cost as much as a new pick up truck with all the goodies, maybe as much as a small home.
