So I've had 2 turtles for about 11 months, they've grown a lot and I've kept them in good condition, but i've been pretty busy working almost every day and cleaning the tank has become a weekly chore.
I have a 20 gallon tank, every week (6-7 days) the water would become so dirty it would be hard to see the turtles. It's a shame when this happens, but it seems like it happens too fast. I only give them enough food that they can eat so there is never leftovers.
I always have to take the turtles out of the tank, use a cup to get the dirty water into a pail, carry the tank to the bathroom so i clean it out in the bathtub (which then has to be cleaned with bleach), then carry the tank back and use a container to make a few trips of carrying water back to the tank in my room. The rocks make for a big hassle too, so I recently took the rocks out. I feel bad because the tank is boring without the rocks and decorative plants.
Can anyone suggest a filter I can use? I have a air pump, which only keeps water flowing through the tank. Thanks
