I noticed last night when i was handling my 4th old boy he weezed maybe 2 or 3 times in 15min, and today i heard a wierd sound coming from the tank (twice only with a hour.) During the day the high side is 90F and low side 84F with humidity around 45-55%. At night the high side is 84F and low side 80F with humidity 55-65%. im trying to figure out what it might be.
