Is the tds meter recently calibrated?
I dunno, it’s my friends. We tested his ro and then mine. His ro came out 0 mine came out 15ppm.

Is the tds meter recently calibrated?
I'm not in an apartment but I am space limited so I don't have a water making station either. I make and store my bottles of rodi and then when I run out I make more but I understand your situation and although your lfs says you're getting the same water doesn't make it true.
I don't know your lfs and I'm not insinuating all lfs do this because I do know stores that are honest and have clean water. But I've also heard of the stores that say how clean their water is and it's dirty when tested, maybe not even intentionally. Membranes wear out, DI gets exhausted, meters are out of calibration and employees get busy and/or lazy and forget to test themselves. But you mentioned high po4 and algae outbreaks and buying your water third party coupled with sps health issues so it shouldn't be overlooked.
I been just using prime with city tap for over 5 yrs with out any issues.Just tested my ro ,the tds meter read 14ppm so I guess that has something to do with it
I didn’t read all the posts but did deal with Dino’s myself and I would say although they are not seen except in certain areas they are still there and toxic to the corals. I would say a total restart would be the fastest way to an SPS sustainable environment.
I would be cautious on adding any new corals since it looks like dinos are still present and the system may not be ready yet.
I don’t plan on adding anymore till I get my results and I get everything back in order. But how long would one have to wait for dinos? Till they’re 100% gone? I’d say they’re about 95% gone.
