A pleco that large cannot hide from your turtle which is usually a key reason they survive. Also at that size your turtle is more likely to just take chunks out of the pleco, torturing it, than to just eat it all at once like a feeder guppy.
I personally think adding fish other than feeder fish to turtle tanks is usually a poor idea because everything you put in the tank will eventually get eaten.
If however, you do want to put a pleco in, I think you'd be wise to put a smaller one in there. The size of the pleco won't deter the turtle from going after it, so bigger isn't better.
As for the algae, do you have your tank near a window? Sunlight really increases algae growth. Most tanks deal with a bit of algae, mine has a persistent colony on the basking dock, it doesn't do any harm to the tank, and cleaning it doesn't get rid of it for very long, so I just leave it.
