.. . and I don't know why but it's obviously me since it's been 3 different brands of filters.
1.) Azoo Mignon
2.) whatever filter came with the Petco Bookcase aquarium kit
3.)an Aquaclear 20 for a 10 gallon tank split 3 ways for 3 bettas and lots of plant
I have 2 theories but I really would appreciate some filter maintenance advice since I only started keeping cycled tanks a few months ago.
a.) I seem to have a lot of plant matter collecting when I have plants and also home made betta spa (Indian Almond leaf water)
b.) could it be that when I cleaned the tank just now I let the motor run for a few seconds before unplugging it when the water level was too low and it burned out?
The other filters - one was broken one day and I never realized when it stopped.
I can't remember the situation for the other one.
Each filter has only last a couple of months. (I have 3 other tanks where the filters are still working at the moment.)
I don't want to break any more .. . advice?
(All my tanks are cycled, are between 78 degrees or 80, and have zero ammonia levels. Water is very hard here in Tucson.)
