I've had my BTA for over 4 months but here lately it stays closed all day. It will open a little at night under blues. It is in a 40 gallon breeder and the tank has been up for about 3 years. It does have a clown that will not leave it alone! My parameters are good except my phosphates have been running 0.05 ppm. Any ideas what is going on?
