Which pump for curing dry rock?

If I had nothing else, I would use the MJ dialed back
You just need some circulation, although more is better than none.

Both!

So far I have the MJ going on one side. I think I might need another 1 on the other side.

I didn't put the Eheim in, but I would think it would be too powerful and shoot water straight up (possibly out of the tank??)

I really like to blast curing rock...
It helps to get detritus out of the porous areas.

Is it ok to lay an Eheim pump on its side, or does it need to stay right side up?

[gobytron]

should be just fine on its side...

You could also just attach some tubing to the outlet...maybe a couple of 90 degree elbows so you can put it upright and your water doesnt shoot straight up...

I am going to hit the hardware store and get a few parts so I can do that.
