Curing Dry Rock Questions

[ronau]

Hello,

I just set up a 32 gallon Rubbermaid Brute with ~18 gallons of water to cure some dry rock I got tonight and I have a couple questions.

What king of flow rate do I want from my powerhead? I tried using a Koralia 425 GPH and it seemed like it barely moved the water. I switched to a Eheim compact+ 2000 and it seems to be doing a great job but I was going to use this pump to run my GFO reactor. Powerhead suggestion???

Secondly, can I just place my heater on top of the rock? Right now I have it attached with magnetic clips but I had to stack all of my rock on the other side of the tub. I would like to fit more in and not worry about it crashing down and smashing my heater.

Thanks,

Ron

I wouldn't use the HCGFO while cycling the rock.
For your setup as your rock is in a pile I would place the pump near one of the long sides of the bin to get a better circulation and oxygen exchange, place the heater in front of it making sure its not banging around.
Hope that answers some of your questions.

Sorry Eli I should have been more clear, this is what I am running:

The Rubbermaid Brute is just a garbage can. As you can see I've stacked my rock away from my heater. I would like to stack the rock all around my pump and just set the heater on top of the rock, is it safe to do that?

So no GFO eh....but wouldn't running GFO encourage the rock to leech out the phosphates quicker?

Thanks,

Ron

No need to be sorry its always good to ask a thousand question than to tell of a problem story...learning curve to all of us..
HC-GFO wouldn't encourage the phosphates out of the rock.It will simply remove what is in the water line.
If you have enough water flow then I don't see a problem placing the heater on the rock as long as you keep up with the water top off making sure the heater is always under water and not rocked around by the water flow...
