Replacement for Magnum 250

[Mugwump]

I set it up as a regular in tank filter. I put some Purigen in the tube and I'll check it in a couple of weeks unless the flow stops or slows down considerably.

I wonder if it'll pack the powder by running so efficiently?

If you mean the Purigen, I don't think so since it's not a powder. I also only put the purigen in on chamber of the 2 chamber tube. It's also in a media bag so it is contained. We'll see what happens over the next few days.

...gotcha....always thought that the Purigen was finer than that....
