Hello , I Set up a brand new 60l aquarium 2 days ago , added gravel tap water and tap water safe and filter because it was very cloudy as soon as i added water. I haven't added No fish and not planning to do so until the cloudy water has gone. Its Still cloudy after 2 days lots of small air bubbles too. i did a test today with a test strip and everything else is fine but the Kh is the highest on the color chart. Can someone tell me why its cloudy and how to make it go away and also how to lower the Kh. Because the cloudy water is really bothering me now. Thankyou
