One thing I notice when I do my weekly manual topup of my reservoir...there is TDS creep every single time. That is weekly. I can also turn the ro/di off for 10 minutes and still get creep.

So what I do is bypass the DI resin for a minute or two until the TDS after the membrane is 3 or less. then I run it through the resin and into wherever I want good water. This saves your resin from a constant butt kicking.

In my opinion doing manual fills in this way will allow your media to go much further. Not that you asked for my opinion but...

Fish room's looking food btw!

Agree with Brett except that the fish room doesn't look like food at all to me. But I'm tired and maybe just not seeing it. Plus I just loaded up on some beef jerky so I'm not all that hungry, no salty snacks for at least 10 more minutes.

I was thinking of getting a float valve but i have been filling up these tubs for a while now and 3 and a half hours is pretty much perfect and the timer was only 10 bucks.

That is a good idea I have noticed that whenever i turn on my rodi without a brand new di it always starts at like 5ppm then goes down to 0ppm.

I can't quite follow your RO/DI plumbing, but tell me you do not have your DI before the membrane.

haha no. lol. I attemped to make a paint drawing but it failed badly. lol the water comes from the one sediment filter on the right unit then into the sediment filter on the left unit. Then i took the line from the ro and ran it to the di on the right unit then back to the left one so that the inline tds meter still works. I dont know if this description is better then my drawing or not but whatever I could always attempt the drawing again.
