This is it exactly. I can get down to 0 for a short time if the membrane is new, 1 for quite some time and then anywhere from 2 - 10 in the first hour or so. If it runs all day it will very slowly go back to sub 5.

TDS for me stays far too high in the first minute. I can't afford to blast through resin like that. Once it's low... it won't creep all the way up to 200 if it runs frequently enough but you never know.

My thing with plumbing direct into ro/di has much more to do with costs of resin than it does with flood fears.

this blows me away.....we all spend X amount on a tank, X amount on lights, X amount on a skimmer, hundreds if not thousands on livestock and then cheap out on something as critical as the stability of the salinity and the safety of the tank.........amazing

Ive been through a couple of the osmolator pumps as well......but in fairness to the pumps, I have been guilty of letting them run dry a time or two

Just because something costs more doesn't make it more reliable than other proven methods.

proven to what?......fail more often then a tunze?....I may be wrong but I have never read or heard of any tunze ever flooding a persons tank......Ive heard of pumps dieing and head units dieing, but I have never heard of one killing someones tank ..... anything mechanical if given enough time will fail.........especially in a humid salty environment

Yes anything mechanical or electrical can fail, and Tunze has both. Lots of people on this forum and many others that don't use Tunze and have never had problems either. Tunze makes a good product but so do many other companies which also have a second level failsafe. Tunze pumps constantly dieing seems to be very common on any forum you go to and it's kind of hard for an ATO unit to keep your reef stable and safe when it's not working. Tunze would be a much better product if you could add your own reliable pump instead.

I have used tunze for 3 years now with out a hitch, still on the original pump. They actually make a relay so you can run almost any pump you want off the tunze controller.

Any idea what the part number is for the relay, Wes? I have been considering getting a Tunze ATO myself as I think they are a great product. I just don't like people chirping that there is only one product that anyone should use and implying that you'd be an idiot for getting anything else.

My TDS is at 0ppm when finished making water, when resevoir is full it climbs up to 50ppm over a 8-10hr period while it is no longer filtering water. TDS probe is between DI cannister and auto shut off valve to resevoir. Is that what your talking about? To add to this thread i use a JBJ ATO with no problems in 3 years.

This is the tunze relay, don't think it will work for us looking at the plug. If i wasn't so lazy I could find the pages i had found earlier about guys diy a relay in to run a maxi jet.

they just show the euro plug. j&l wouldn't sell you that =)

i was worried my evap rate would exceed what the tunze pump can do but so far it's working like a champ. never let one run dry and never had one fail (as a result i think).

I don't care what topoff you run so long as it's a tunze! <- if henry ford was a reefer...
