It did about three weeks ago when we had a heat wave and I had a heater in the tank.
I took out the heater and my tank stays steady at 72 now, even at night time because I have a small room and have two other tanks in here as well.
Well what happened was that my whole top of the tank was covered in salvinia, so I took out 3/4 of it, and even then, three days later, half my tank is covered already, so I don't thin kit was that I took them out, they grow pretty fast in my tank.
I will do another test tomorrow morning to keep this updated I changed the water to late and now my daughter is sleeping.
must....have.....more....moss n shrimp!!!!!!!!!!
