So I finally got a Triton test for my propagation tank and I was pretty surprised - high levels of Sn, Li, Br, V, Si and Al. I use IO salt, and do ~20% water change per month, plus water sent with corals. I'm kind of surprised at the high Mg levels as well, since IO is pretty low on Mg, and I don't supplement any. It is in a garage, where a car is parked.
The surprising part is that my display doesn't have high levels of any of those elements, even though it uses the same salt. I have rigid PVC in both tanks, under three years old for both. I did have a return pump die recently, and I replaced a cheapo pump with an Eheim Compact 5000. The tank has been up for about eight months now, and I've had some mediocre growth marred by some random STN. I've used a polyfilter on and off, but it doesn't change color - just gets brownish indicating organics.
Any suggestions would be appreciated! My full results are below. Thanks!
