Hey guys!! I've had fish tanks since I was 7 I'm 25 now. So I pretty much know all the ins and outs of fish, equipment, water quality all that good stuff. I've ran into something I've never had a problem with before....I've had my fresh water 45gallon tank set up for months now (like 8) and every time I do a water change the water gets this cloudy appearance for a LONG time. Like I'm talking it doesn't start to clear until it's time for the next water change. It's kinda like a cloudy white ish...not milky but like a slight cloudy. I've tried water clarifiers...I've changed my filter... I've done everything I could think of and it's just not going away...oh there's only 4 fish in there all about 2 inches so I know ita not overstocked.
