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?
I am very interested in those monitors, where can I get ammonia and nitrite, monitors with aleters? I am planning on enlarging my small 300gal pong to almost 500gal.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.
