My HOB filter for the 33G tank has gone bad. It was in use for a little over a year. I will know the exact cause of problem when I get back home and would decide if I want to get another HOB or a new cannister. Fishes are all fine, thanks to Pallavi who has been doing the feeding routines and the water changes.
With the rains setting in seems that the outdoor tub is a lot of activity with the guppy females proceating a lot. Another week and I will be home and have a neat update of how the tanks are with three months of my absense.
