How do you deal with salinity changes (what the skimmer pulls out, acclimating fish, etc)? I guess the idea is that if you stick with a brand of salt, every time you dial in your salinity, it will return to the base "tested" system...is this line of thinking correct?
Well, specific gravity needs to be dealt with by topping off with fresh RO/DI water, like you'd do in any system. It's the saltwater that is the issue...Sticking with one brand of salt at least, in theory (depends on the manufacturer's consistency from batch to batch), is a good way to eliminate at least a few possible variables. Triton contends that you can use any brand of salt. However, their thought is that the system still needs to be "calibrated", if you will, to achieve NSW parameters on trace elements. Once you set the parameters, you're maintaining them by dosing the proper amounts (determined through testing) of specific trace elements. You're NOT depending solely on the salt mix to supply them. And, since you're not relying on water changes to replenish trace elements, you're giving your reef just what is being consumed by the life forms within it. Is it a perfect system? No, of course not. But there is a certain elegant simplicity that will, hopefully- translate into success on a practical level for a wide variety of reefers. Again, there is a lot to learn, from both a chemistry perspective AND a philosophical/husbandry perspective...Really cool stuff, and we're looking forward to working more with it and learning from/sharing with others our successes and challenges.
