Alright. Trying to work out some kinks before I begin the actual construction stage on my fish room. I have a this pond... panic: it is the overflow from my spring. The water we drink, and I use to do tank water changes currently.) I've actively tested it, and quality-wise, all is perfect. I would just probably want to filter/uv sterilize it before use? Maybe? Feel free to chip in. I, just worried about microbes/tiny critters/unpleasant bacterium. Anyway. It pretty much guarantees me thousands and thousands of gallons of available water to WC in my future fish room, but I'm not sure how I should go about it... Pump it into a holding tank and filter/sterilize before use? Throw a pump in it and go? Keep water in holding tanks/barrels and let it age? I'm really not sure the best route to take, and in order to purchase and set up all necessary supplies, I really would need a game plan! Anybody?
