I know this is the common question, and I read through the forum. I just can parse the calcuation together for what I need. my apologies.
Allright, I got a 20 gallon tank with a over the side filter that was dieing and two RES (one female one male). Couldnt keep the tank clean.
My g/f bought me a "ZooMed Turtle Clean Filter 318" which is clogged in about two days.
Since we decided it wasnt enough we went and bout a "Zoomed Turtle Canister Filter 501" which didnt seem to work at all.
So we thought maybe a bigger tank and got a 55 gal glass aqarium put in 25 lbs of river rock on the bottom and have a medium zoo med turtle dock. Since the 501 wasnt doing much I spent the money and bought a "Fluval Internal Filter 4 Plus". Most of the floaties are gone. But the water is still very murkey. Do I need something more pwoerful? $250+ on a free turle is starting to be a little disconcerning.
Not to mention the guilt I am feeling becuase the turtles do not look healthy. Both shells lack any real color and the female has a smooth spot on her shell. Mind you this is how I got them, but I am trying to help them and give them good living space.
What filter exactly do I need to function for two 6" turtles in a 55 gallon tank?
