Well I recently received my purewaterclub.com RODI
unit the other day, which has actually done a terrific job! Only problem with it all is I ordered a 6 stage unit, and also ordered a pressure gauge and a connector to fit the garden hose... But instead I got the pressure gauge, a 7 stage unit, and no connector. But I just went to Lowes and got one for about $4. No complaints here! The unit installed great, and after a little troubleshooting I got all the hoses and everything connected the right way, and fired it up. Ran GREAT! Not a single leak anywhere and is putting out just as much water as it should with 0ppm TDS
The trouble I'm having is this is the initial fill up of my 125 gallon tank with about 90 lbs of dry aragonite sand, and about 110 lbs of caribsea, and Marco dry rock. While filling it up I'll test the water from the RODI
unit, and get 0... Then I'll test the water in the tank and get ~150. My tap water reads ~300.
Am I getting higher levels in my tank just because of the dirt left in the sand and the rock? Or is this natural? I've been running one of my Eheim 2217s filled with filter floss to help filter out some of the floating dirt from the sand, which has brought down the readings a little bit, but not a lot. Should I drain some of it and just keep filling until I get 0ppm in the tank as well?
Sorry for all the questions, but when I had my smaller marine tank I just bought water cuz it was easier and I didn't have to worry about mixing it or anything, but this was the cheaper route to go with a bigger tank
Thanks in advance for any help!
