Update time!
I was sure I’d need to change my carbon filters by now.
Pre filters are turning brown but no significant drop in pressure.
TDS post membrane is 4-5 and holding.
No issues since having brought units indoors.

What test kit is that and do we know what an acceptable amount of chlorine is in a reef tank?Okay here we go…
This is a Salifert chlorine test. It does read at parts per million.I’m testing post RO carbon filters in order to determine the need for replacement. The RO unit has been up since mid July and producing a minimum of 60 gallons of usable water weekly.
post membrane,after both, before the DIDo you sample and test after each carbon housing or just after both?
post membrane,after both, before the DI
Still holding. The pre filter is brown. No drop in pressure I can see
The post membrane TDS is now 3!
Was 5 when new. Is that unusual?
Hey Woodyman, happy holidays to you. Been awhile.Maybe a seasonal change in your water parameters. Have you compared the incoming TDS to what it was before?
Hey Woodyman, happy holidays to you. Been awhile.
Yes,I checked and its about the same, 150 ish at the faucet.
Yes, the change over from out side to laundry room has made a huge difference. Best thing that we came up with. Can't thank you guys enough for walking me through the process.It has! Happy holidays to you as well, thankfully everything is still working properly for you!

Think you mean will decrease the rejection rate, with a lower water temp.A drop in water temperature will increase the rejection rate.

No. With a decrease in temperature rejection rate will go up and permeate flow will go down.
with higher temps the membrane will reject more TDS, the rejection rate will increase not decrease.
