After a two month wait from order, I finally received my Red Sea 200 G2 Max. I paid LFS to put everything together, and because of the long wait Red Sea threw in a large bucket of salt. But I just realized he (LFS guy) installed my reef tank, with my nice boxed live sand that i purchased separately. when he came to put everything together, he brought live rock that the LFS owner had selected for me on his own. Installer scaped it for me. He brought rodi water as well of course. He set up everything nicely, although he forgot to make a couple of connections from the ATO the controller, as well as I think he did not turn the reef mat on, because neither of those were connected to the app so I had to do those things, which I not easily did because the ATO cable is five pins, and it was just really hard to get a connection, and in that process some of the cords became a little bit cluttered. I need to better organize the cables. The ATO became functional and as per my red sea reefer app all is functional; however i did not see LFS mix salt in which I just never thought to ask him about because I presumed he knew exactly what he was doing. I put my finger in the sump and it certainly tastes salty so maybe they brought the water here already mixed with salt. IDK. i do not have a salinity test instrument yet. He told me it would take maybe six weeks to cycle my tank. I add a small amount of ammonia and microbacter every day, though it's only been the second day now. I never actually saw the installer mix any salt which puzzles me. I would not think he would've brought the water already salted. Maybe when I was in the other room he mixed the salt. IDK i better call tomorrow to clarify that because of all the things we discussed, mixing salt was never one of the topics he brought up or I thought to ask about. He just told me that they gave me about a one year supply of salt. Hypothetically, if he did not mix any salt in my tank, can I just slowly start adding it into the sump over the course of the next month, testing the salinity along the way? It would seem to me that slowly adding salt over the course of the next week or two or month would be practical, going to the sump first would not disturb the tank itself. And then the sump will pump the salt water back it into the tank. I hope this is correct? It's too late. I can't take out all the water and remix it. although I'm quite sure since the sump water tastes salty to me thought it was mixed in. what I found interesting is after he left and I got the ATL going a few hours later, the ATO sucked in about 4 gallons of water and brought the sump from about 40% to 90% full m. The app for the ATO shows "above full," but no alert or anything. I think that's all good and just how it's designed to be.
