Hello! I changed the plans with having an outdoor pond. I guess its better to have a heated pond indoor than having the pond outdoor in the cold windy areas where your electricity will skyrocket!! So im going to make the pond indoors in my pool table room =] But im going to make the pond size a little bigger. Im going with a 12'x8'x5'. Now with that size indoor pond I can have more space for my fishes to swim in. I still have some new questions though on the aireation of the whole pond....how can I aireate the whole thing or do they need air in that size pond? I need to know if its going to be needed to enter that gas exchange process also for that algea problem stuff and the ammonia. How do I heat it? Oh yea does anyone have experience with those water heaters at HomDepot? are those good heaters? Filters I have already planned as im going to make my own 55 gallon bucket filters like about 4 of them so like 2 on each end of the pond on the width side and the main filter im buying at a pond store that filters 8,000 gallons on the rated tab and only on the red sale for $398.98/ original price was $848.89....so please answer my questions =] as i'll get this pond building started! once its up and running this baby is gunna house my Monsters =]
