So i went out of town for a little bit over the holidays but my parameters stayed stable. 1.026, 0 nitrite, 5 nitrate, 0 phosphate mag and calcium are on the high end of the scale, ph 8) the whole time i was gone. When i left it was full happy and healthy. I came back about 2 weeks ago and its been shriveled up but periodically seems to reinflate some then goes back. A few days ago it was stretching its self out but now its back to this.. its definitely alive and reactive... But curious if anyone has any thoughts on what i can do to get it back to normal. My other BTA is just fine and happy.. i appreciate any thoughts also the tank is about a year old.
