Thank you for all the help. I have yet another problem. I did a 50% water change in my 10 gallon tank yesterday and now its so cloudy i cant hardly see in it. The only chemicals i put in it was the water conditioner for tap water and about a level tbsp of salt. I changed and cleaned the filter also. What have i done wrong now. i tried to post this before so you may see it 2X sorry!!!!!
