Why is my swimming pool water green even though its fully chlorinated?
Oh dear! A GREEN POOL? This is a problem! I dare say this is not the right color for a proper pool, perhaps a pond maybe? Get to checking your chemical composition on your pool, check to see what is high and what is low, then fix it. Or take a fresh sample straight to the pool store for diagnosing! You have a major malfunction and need to get it right before swimming in it. Pool water should be clear, clean, bright and sparkling, with a proper chemical balance. I had mine turn ONCE last year, after we went to Durham, NC for some surgery on my niece and I let the pool fend for itself. Took two days to get back on top of. Never let that happen again! But it was only a slight greenish tint, resolved with a shock and a chemical to drop the particulates out. Cleaned right up! Hope this helps you! Good luck!
