Is my RO/DI system working??

[rdefino]

I just bought and setup this RO/DI system:

I just had the PH checked and it was about 8.9-9.0. My LFS is about 8.2. How do I know for sure that RODI is working correctly? Any way Of knowing. I don't want to use it in my tank and kill something.

Thanks

You'll need to get a TDS meter. You can pick one up from Ebay for about 25 bucks

You'll also want to test for chlorine and chloramines - the TDS meter won't pick these up

As long as you have a carbon stage and it's changed every 6 months or so it won't be a concern. Testing for those seperately wouldn't be a benefit.

How do I test for chlorine and chloramines?

 

[MarkW19]

Get a chlorine and chloramine testing kit

I guess you don't know how old the unit is - I'd get a new sediment and carbon filter for it. Then change them every 6 months as steve said. That way you should be ok.

The system is brand new. I just want to make sure that I'm making the same quality water that I can get from ky LFS.

Just test your TDS from your unit, then test the LFS

No need to test for that stuff with a ro/di unit, it will remove it all.
TDS= total dissolved solids, on a new unit it should be 0. As the resin in the di wears out it will rise. If you can get a DI cartridge to last a year as they advertise that would be a miracle. I'm lucks if I get a few months out of my dual DI system. It will all depend on the water quality you start with. Test your water from the tap with the TDS and then the end product and you will see the difference.
