The first test shows a lot of contaminants in your RO water, especially the copper. Are you making your own RO? If so, I would change all of your filters/media or increase the stages to maximize quality product water. Your tank water seems fine overall as far as the main elements, but like your RO water, contaminants are up and should be addressed. Copper should be zero, along with aluminum (which is certain forms is harmless), zinc is high, vanadium is a little high and your salinity is low. I would use polyfilter, Brightwell's Purit (small amount) and maybe cuprisorb to reduce the unwanted metals. Also, PO4 is high, but if you're not having any issues with RTN or algae, it may be fine, but slowly reducing it will help.

weird thing is hanna checker was showing me .06

it showed my salinity was at like 33ppt?


With these test results is your tank doing good?
I would say its doing ok, nothing growing like crazy but nothing dying either

I've found that my PO4 is slightly lower with my testing, but higher with ICP in general. Regarding salinity, I use a trusted refractometer and my glass hydrometer to verify. I trust the ATI salinity results, as they match what I'm getting with my testing. I'm not a big fan of digital refractometers, I find most of them are off by a point or two. I think a friend of mine has the Hanna one and it's pretty damn close to being accurate, but all of the Milwaukee ones are terrible IMO. Spend the money and buy a VeeGee refractometer designed for seawater.
