So I just set up my first freshwater tank after being out of fish for a while. It's a 125 TruVu acryilic with built-in overflow and a 40 breeder for a sump. Built my own stand, canopy, and wet-dry for it. It was running crystal clear until I put a large amount of wood and rock into the tank. It became very cloudy with a green tint to it right away and seemed to get worse over night. I washed it all really well before putting into the tank. Could this be tannins releasing from the wood? Whats the best way to get rid of it? I just did a 50% water change and it accomplished nothing. Will adding some carbon in bags to the sump help clear the water? I was thinking Boyd's Chemipure since it comes in mesh bags already? Any advice is appreciated. I don't think it has been running long enough for it to be a bacteria bloom, and it was the instant I put the wood in the tank so I'm assuming that's the problem.
