Thoughts? Sure! Always have lot's of those.
First, I invite the original post-er to give us a call at 513-312-2343 so he can experience what it's like to talk to a water treatment professional rather than a vendor of pet supplies.
There are lots of easy troubleshooting we could do right off the bat. For instance:
*What is your water pressure? Because you are on a well, your water pressure will likely be variable as it is controlled by a pressure switch. Conversely, your water pressure may not be variable if you have a variable speed well pump (most people do not). With water like yours, high pressure will be your friend.
* What is your RO water TDS? In your case it will be critical to have a TDS meter probe that reads in THREE locations: tap, RO, DI. There is only one meter on the market that does this, and it was developed by HM Digital at the long-term and repeated prompting of Buckeye Hydro:
TRM1 Tri Inline TDS Meter
*Hopefully you are not running one of those ill-configured "water-saver" units. That would be a horrible fit for your situation.
*What is your recovery? In this hobby, "
recovery" is usually talked about as your "
waste water to purified water ratio."
*What is your water temperature?
*What flow (volume per unit time such as gallons per day) is your RO producing?
*Hopefully you have a whole-house water softener that is in proper working order. Do you have other issues such as iron or manganese for instance?
So that's where we'd start. Best to give us a call when you are in front of your system.
