I read a thread on R2R about the ST and only one person claimed their PO4 was off every once in a while. Also seen that the reagent disks can be hard to get at times. But I haven’t found a lot of bad yet. I’m going to do some more digging before I drop that kind of money on one. But so far, I’d get this over the trident.
I added the T5’s later. I didn’t do any acclimating. But if you concerned, just run the T5’s a few hours a day and add time every week until you have them on as long as you want.
