Hi. I filled my 180 litre tank five days ago, added dechlorinator and bacterial startup and everything was okay, I was going to leave it like this for about two weeks before adding any fish but then it started going a white hazy colour so probably unwisely I emptied it and refilled it with fresh water, added the additives again and everything was crystal clear for about 24 hours and now I have my white haze back. Is this a battle between good bacteria and bad bacteria causing the cloudiness and can I expect it to clear when the good bacteria wins, hopefully! How long would this take to clear if it is indeed the problem or am I on the wrong track completely and is it something else. Gravel was thoroughly washed etc before adding water. Heres hoping for some advice. Thanks.
