Question: About plumbing the chiller

[fish590a]

I have 1/5hp JBJ chiller (min. 480 gph).I have eheim 1260 now but I can upgrade to eheim 1262. Can I use just one pump for return and the chiller? And should I return the water from the chiller to the sump or to the display?

I would recommend a separate dedicated chiller pump.

I found that my JBJ chiller put too much pressure on my return pump to use just one pump.

After trying it, I had to buy another 1262 just for the chiller.

Cheers
Josh

Do you return your water to the sump or the display?

Do you have a controller for your tank?

The reason I ask, is that if you have a dedicated chiller pump (which is a good idea), that you will want to turn it off when the chiller is off.

The only problem is the added heat this additional pump will add to the tank.

So by using a controller, you can shut off that pump when your tempertaure is at it's set point and only turn it on pump when the chiller is on.

that makes a lot of sense but no controller for now.

My chiller is on a dedicated pump and is plumbed as a closed loop drawing and return to the sump.

I have the closed loop at the start of my sump (just after the drops from the display), this way the cold water mixes with the water coming from the display and equilizes by the time it reaches the end of the sump and returns back up.

I to have a separate pump for the chiller and UV from the sump back to the return.

Does anyone know if stagnant water has an increased calcification rate?

I never let the water in my chiller stagnate. My chiller only came on a few times a day in the summer time. I just didn't want the deposits building up in the plumbing. Though I have no evidence that deposits build faster under stagnant water than moving water.

I'm using a dedicated pump for my chiller and it's plumbed in a closed loop with the main display so it's used as circulation as well.

I use only one pump from my sump to chiller to main tank. I don't know what the temp. would be if I didn't do it this way but it saves me money on running a second pump and my chiller isn't working so hard.

I have my chiller plumbed on one of my drains, so I do not need another pump.

Wow, that's an interesting way to go. I would have never thought about it doing it that way.
