Anyone who keeps rays can you please share some numbers?

Tank
Ph 6.4. Fairly constant
Ammo 0 (had a spike recently after changing all my sand but all is back to normal)
Nitrite 0 (always)
Nitrate 2.5ppm at most goes up 2 colors or so on api chart but not recently.
Tap
Ph 7.6 :-\
Ammo 0
Never tested the others

My ray tank. Tap is same other than 0 nitrate. Sorry I do not have a tds tester.. those not.knowing is means total dissolved solids.

Interesting... But why the big difference 3-4?
Your not telling us everything.. Lol ?

Are you adding salt to your systems or do you have any kind of substrate that could be adding calcium or metals into water. I am very surprised that your TDS has jumped 3 fold from the water main. Water is like a sponge and will absorb or suck up just about any kind of material it comes in contact with. We have a huge RO/DI system at work that produces 300 gpm and it takes our TDS from 140 range to around a 3 like your RO is doing for you. If the water sits long enough in 316L storage tanks the cold stays the same but the Hot tank 160 deg plus will climb back up to 100 TDS. The belief is the hot water is pulling metals from the side walls causing TDS to climb. You need to think hard and look hard to what in your system could be leeching metals or minerals in. Check TDS on your drip water as well.
I have NO clue why the growout/pup tank is so high other then the fact that tank is NOT on a drip. I broke down the canister and it was pretty nasty. The growout/pup tank is independant of the big and lil systems. Not tied together.
This tank's Nitrate wasn't even orange I'd call it 10 or less. The sock on this tank gets changed at least every week, sometimes twice a week. Yet TDS is still 3 fold of the water main (after drip) and the 2 systems that are drip fed.
I don't even bother testing Ammo, Nitrite, and Nitrate as they always test the same, the filters work. I have always thought there must be more important #s that are being overlooked. Maybe TDS is that #.
Nobody's noticed that half the TDS of the drip water disappears with aging? I'm still in shock. So aging the water could cut TDS in half when compared to a normal drip system? Unless I'm misunderstanding something here?
Growout/pup tank test viles after about 10 min........
