Lance's 225 gal tank

[Delphinus]

How high up the reactor are they running when moving?

If it were me, I'd take the filter right out, and take out enough pellets so that it can run full bore without burping any pellets into the sump. No more than 1/2 - 2/3 up the reactor.

And save up for a MR-1 reactor (actually it's pretty cheap all things considered).
