best way to make water colder

[Treezer8]

Got 30gallons of water in a trash can, ready for water change. I used a new pump to mix it around, and it got kinda hot after a while so I need to cool down the water by like 10 degrees.
Should I just use ice? only thing I can think of

Bags of ice(no holes) would be best, you dont want tap water to mix in with your RO water.

Carry it outside for 5 mins :p
Its -20 deg c here haha

 

[Treezer8]

I had already put like 3-4 handfulls of ice cubes in, thinking it wouldn't be a huge factor.

Put some of those ice-cooler block things in now.

Should I check the water for anything for I put it in?

 

[Bifferwine]

Nah, it should be fine. A few ice cubes are not going to hurt anything. If you don't need the water *right now* you can just wait. :)

Yea, I've decided to wait till morning, and I'll leave the bin next to the door and leave it open since it'll be in the 70s over night. I'll leave my bilge pump on low and then i'll change the water in morning

Fill up a two litter coke bottle or milk jug with water and freeze it then when the need should arise drop it in and let the cooling begin. Homade chiller southern style:mrgreen:

it was a 1200gph mag pump that I'm going to be using for a sump in a few weeks. I usually use a different pump. But it probably wasn't just that, the pump wasn't too hot at all. It get's kinda hot in my closet and I had the door closed in there

 

[d2mini]

Whew, i was gonna say.... throw out that pump! haha

 

[Treezer8]

Whew, i was gonna say.... throw out that pump! haha

yea, I'm actually going to start my diy thread on my first ever sump later today
