I just set up this 46 gallon bow front tank. We got the tank from a friend that had it as a salt water tank. After a week of scrubbing off the deposits all over the glass (lots of elbow grease & razor blades), I got it cleaned up & ready to go. Tuesday I added 2 bags of Eco Complete and 1 bag of gravel (65 lbs). I put a piece of driftwood (that has been in my other tank for months) and some plants & filled it up (carefully so as not to stir the substrate). I also put some of the media from the existing tank in the filter (it's an Oase 300) to get it going.
Wednesday it was clear & looking good.
Thursday morning it looked like this - totally cloudy. Last night after work, I removed out the used media and added a small bag of purigen. It's still this cloudy this morning. (sorry the picture isn't that great - my light is coming in today)
The gh, kh, & ph are all in normal levels (obviously, the nitrites & nitrates aren't showing up yet). What should I do? Why do you think it turned so cloudy after 36 hours?
