Hey all, just joined. We live in SOuthWest GeorgiA (see what I did there?) USA. Two and a half years ago we purchased our place out in the boonies and it included one and a half ponds. The one pond is a four tier set up with a poorly constructed bog filter in tier 3. The fourth and final tier is about 1,400 gallons with about twenty goldfish and one (hopefully two) butterfly koi. I say hopefully because the second pregnant female is MIA since we released her about two and a half weeks ago. The other half in the pond count is actually what I've heard referred to is a "sky pond." That being it's a depression in the ground that fills with about a third of an acre of water when it rains a lot and dries up or gets very close to that once a year. Wish I could keep it full though.\n\nI'm looking forward to learning a lot more about keeping up our garden pond.\n\nOne question though. We have a 1,500 GPH pump that circulates water from the main pond up to a small tier that overflows into a larger tier with water lillies, then overflows into the third tier filled with papyrus as a bog filter then finally spills into the main pond. We have finally found all or at least 98% of the leaks in the system and are able to run the pump for long times with little water loss. The question is what is the conventional thought, should we run the pump 24/7 or on a timer for a specific period or periods each day. Is there an adjustment based on season/temperature?\n\nLookng forward to all replies, thanks.
