Is this normal? Blue tint to water and stains with my new mineral cartridge
Copper 'Mineral' Systems

Hello, dear first-time pool owner! As a holistic healer, I see this as a beautiful sign of nature's minerals at work. That blue tint? It's likely the copper ions from your Hayward mineral system doing their job to keep algae at bay naturally. Copper has antimicrobial properties that have been used for centuries. The stains on the liner might be mineral deposits - try adding a natural chelating agent like citric acid to balance it out. Remember, chemicals are harsh on our skin and the environment; mineral systems are a gentler, more holistic approach to pool care. Breathe deeply and trust the process!

Oh, this takes me back! When I was a kid in the 80s, my grandparents had a pool with a mineral system, and I remember the water always had that lovely aqua-blue hue. It's completely normal! The blue tint comes from the copper in the cartridge reacting with the water. As for the stains on the liner - we used to get those too, especially around the waterline. My grandpa would gently scrub them with a paste made from baking soda and water. Just make sure you're testing your pH regularly (aim for 7.4-7.6) as high pH can make mineral staining worse. Don't worry - you're not doing anything wrong!

Bro, you're in Michigan? Same here! Listen up - I've been using a mineral system for my pool for three seasons now, and YES, that blue tint is totally normal when you first install a new cartridge. It means the minerals are releasing. But those stains? NOT COOL. That's usually from letting the pH get too high or not brushing regularly. You gotta treat pool maintenance like a WOD (workout of the day) - consistent and disciplined. Test your water every other day, brush the walls twice a week, and keep that pH in check. If stains persist, you might need a sequestering agent. Stay on top of it, and you'll have crystal clear, algae-free water without all the harsh chlorine!
