Bought a UV sterilizer one week ago. Made a measurable difference so far. But still nowhere close to clear water. I'm just at a loss. Can anyone give me tips for possibly preventing this in the future? It has been such a downer on my centerpiece tank, and none of my other tanks have gotten even a slight bit cloudy, apart from tannins. Nothing changed on this tank besides the high end light, but it's practically dialed in to cheap amazon light specs to prevent algae. Am I just unlucky? Does an exposed planting substrate increase risk? Enlighten me please 🥺
