Does anyone know why my TDS keep climbing so rapidly. I just changed all my filters a month ago and had readings around 3 or 4. A month later and I'm getting readings of 65. I have two sediment filters, two carbon filters and a DI resin cartridge.
Tap water is around 195 TDS.
You don't have an RO membrane? DI resin wears out real quick without an RO prefiltering the water for you. A tap water TDS of 195 is moderate. I don't see the need to run dual sediment filters. The dual carbon isn't such a bad choice though. Add an RO membrane before the DI and you should be good for quite some time (albeit you DO have a freakin 250 gallon tank!!).

Sorry, should have included that. I have a 60 gal a day RO membrane thats only a year old. Could it be toast already?

Yep. You're running a 250, I'd imagine you're going throug a lot of water. I wouldn't be the least bit surprised that your RO is done. Most people burn out their RO membranes in 8-18 months. What color is the resin in your DI?

The resin is about half black so im assuming its got some life left. I guess I'll order a new membrane.
:x-mas:
Good plan. Black? Not dark purple?
What's the TDS of your feed water? Does your system have a flush system?

He said the feed water is 195 in his first post. ;)
I think his RO is way past be able to "fix". Regular flushing will lengthen the life of an RO membrane, but won't pull it out of the fire. :)

I was reading on Reef central that the flush kits don't work. Has anyone done before and after tests to check that out?
