Hi,

I hope things are going better for your female. I have a 120 gallon tank for winter time.I tried a fluval and it wouldn't work. I returned it and bought a Rena and it has worked very well for several years. I have my large slider and two painted turtles in it. Most of the time as soon as it is cleaned it primes itself. Once in a while we have to prime it.

Hope this helps
Linda
