Temporary high phosphates for SPS?

Are you able to put GFO and BioPellets on both tanks to start before you combine them?

Salinity is huge too. I combined two tanks once, not knowing that my salinity was waaaay off in one of the tanks (thanks to a plastic hydrometer) and the tank with the lower salinity's inhabitants all died. (mind you, this was just combining inhabitants into one tank, not sharing system water like you are, but still the same idea).

I agree, and ideally want to get all parameters the same before combining the tanks. Salinity is very close to the same, though, as when I do water changes, I only put new SW in the main floor tank, and the downstairs tank gets the old water from that tank. Saves on salt costs....

And by moving my GFO over to the downstairs tank sump, I have brought the P04 down to .62 when I last checked a few days ago. I also just changed out the GFO, so will check again in a couple days, and hopefully it will be down more. The good news is that the main floor tank (with the SPS) still has zero phosphates with just the bio pellet reactor running.
