my turtle constantly gets algae on his shell and i scrub it off every time.
i keep his tank clean and clean it every two weeks and i also clean out his poop when its small enough to scoop out. there is algae on this fake rock and i scrub it off every time i clean but it ALWAYS grows back.
his filter had the carbon missing he would get algae everyday, and i would scrub it off everyday. i put new carbon in it and he didnt get algae as much, but once a week.
where does this algae come from? its really hard to scrub of, and i think it hurts my turtle when i scrub him with the tooth brush. he opens his mouth and clicks.
it alway comes off, excepth this time, not as much. i think the reason why now is because hes in the early process of sheding and its under his scutes.
