I noticed that other day that I have a yellowish tent to my tank. (everythig looks yellowish) I checked all of the levels, I am sistamatic with my water changes, I cleaned the glass to see if perhaps it was an algea bloom, basted all of the rocks to see if I had setiment on them. None of those seemed to have made any differance. I was just woderign if other people have experianced this and could lead me in th eright direction to correct it. Thank you everyone for all of the help that you offer on this forum. It would have been cotastrofic to get this tank going without the help of everyone here.
