Which pump for curing dry rock?

[Easto]

I have 50lbs of Pukani rock. It's been in bleach and acid already.

Currently it's sitting in a 125L Rubbermaid container. I'm making my first batch of RO/DI water so I can get rocking.

I have a Maxijet 1200 pump that came with my BRS dual reactor.

I also have an Eheim 1262 pump that I plan on using for my tank when the rock is done curing.

Which of these two should I use in the Rubbermaid for water movement?

Will the Eheim be too much? MJ too little?

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.

I used my 1262 for the same thing, laid it on its side. As long as it's fully submerged it doesn't matter which way it sits. Don't wast your gas or money. Lay it on its side and let it do its thing.
