Hello...i was planning on building a 12'x8'x4' above ground pond with 2 viewing plexiglass in the front.But When I did a re-check on the available space in my backyard...i was only limited to a 9'x4'x4' above ground space.Some of my questions are what should I do to have a stable ground since where im going to put my pond its a sandy bottom...? Should i put concrete on top of the sand for dig like a foot in the sand and fill the whole 9'x4'x4' dimension with concrete then after its done curing and drying...i can actually start building the above ground pond.Also here in California,Daly City...we get kinda chilly during the day sometimes but mainly during night time...how should i help keep my pond heated as im going to add a couple of S.A's Fishes in their...? I was thinking about building like a wall around the pond like 2' from all the sides and a roof on top so no rain can fall in and stuff. Its like a lil shack. I was also thinking of this because im going to have a couple of electric outlets for my equipments to run and we occasionally get a rainny day out here every couple of weeks and I hate to have a single drop of rain get into an outlet. =/ This will also be a place to put my fish food,medications,filters, and im also gunna hang a large and long Light Fixture above the pond for light...but I Dont know where to find one...Do any of you guys know where I can find a cheap but large and durable light fixture strong enough to light to whole 9' pond? How should I heat the whole pond to like somewhere like 78* degree's...? I'll try to keep the whole shack insulated to keep in the warmth without the cold getting in. As for filtration I was thinking about building 2 bucket filters on both ends of the pond and buying a main pond filter made for 4,000 gallon's of pond water. Oh yea...is it possible to heat the pond with having a single 300 watt heater in each bucket filters to heat the pond or is that still gunna keep the pond below 78* degree's? Well im still thinking about some other questions that I may have on the process of building the pond...Hope you guys can help me in anyway possible =) Thanks in Advance
