I just had to buy a mag 12. that should give me close to 600gph after I finnish plumbing in my UV

Well, unless I see a MAG 12 on sale for $20, the MAG 7 will have to do for now.

do you have another mag drive pump laying around? you could "T" them togeather at the input to raise the volume.

I picked up 10 fuses today so if you need on in a emergency you can come get one. only 10.00 ea :mrgreen: :wink:

Nope, no spare pumps laying around. And I did blow another fuse this afternoon and no, I'm not giving you $10 for one! :razz:
This thing is quickly becoming a pain in the butt! I may, for now, swap the MAG 12 return pump with the 7. The tank can survive for now with 500gph return, and then I can use the 12 for the chiller. If that still doesn't do it, there will be a chiller for sale in the 'for sale' forum!!

who else has blowen fuses? I am curious to see if the "low flow" is common to all use fuse blowers. I had 200 gph flow and had to have a 12" fan on high 1 foot away to keep it from blowing more.

Brad had his in a open area with ambiant ventalation but with only 135 gph and blowing a fuse every time you looked at it wrong.

?? anyone else.

I narrowed my cycle down to 2 degrees and no problem but befor with the lower flow that would blow the fuse with in a day. if this is working good tomorow still I will try turning off the fans in the tank and then sunday I will try turning off the fan in the crawl space and see if I am going to blow a fuse still with the proper flow through the unit.

I dunno. I think my setup wasnt too shabby.

1" ID tubing, thru to the chiller and then out. total of about 6ish' of tubing plumbed to a mag7. Had two fans blowing cold air from my central AC across the back of the chiller. Blew a fuse.

Now I have moved the tank downstairs, added the UV filter to the loop (large 1" intake on it) and added about 3-5' more in tubing...

I never "measured" the flow, but it was decent, especially in the first setup.

ok so now it has been a week sence I upgraded the flow to the maximum level recomended and no fuses blowen. this is with a 2 degree set point and no fans on the tank. my tank has ~ 78.3 degree every time I look at it give or take 1/2 a degree.

Steve

any updates brad?

Yup, I turned the controller to 4 degree set point and put a fan in front of the unit. Haven't blown a fuse for a week or so. There's a thread on RC where some guys changed the size of the plumbing fittings going in and out, which increased the flow rate a lot, and prevented any fuses blowing. So, I can add a larger pump, or change the fittings. Although, I find that when I set the thing to a 2 dgree swing, my tank sat at 81.5 degrees F. Now with the 4 degree swing, my tank sits at 81.5 F. :rolleyes:

chiller
 

After reading this thread, it seems as though in-line chillers can create many complications when they don't work properly. I am currently in the market for a chiller myself and from what I've seen so far, in-line is not the best way to go. There seems to be many variables that can go wrong.
I would pull hairs if I had spent $700 on a chiller and had to muck around with plumming, fuse, pump, etc. It just doesn't seem right.

From what I've gathered, drop-in coil chillers are quite portable and efficient
No plumming, pumps, or leaks to worry about. And for the price difference, I think it is well worth it.

Brad, Steve, if you had a choice, would you buy this product again?
If not, would you consider the drop-in coil? Why or why not?
