My salinity is 1.023 never had no problems and corals grow like weeds. Been doing this for over 20 years. Different strokes for different folks that’s what makes this hobby great.
I'm surprised this is working for you. I lost 4or 5 nice colonies over a few months when my SG crept down to 1.023 because of a bad refractometer that was reading +.005. In my experience refractometers tend to creep up when not calibrated so I aim high at 1.028 to avoid going to low.

Probably an issue of stability more so than the actual salinity.

Not so curiously, this is another one of those subjects that I seem to find myself and explaining and repeating more often than others. Anytime I'll send over some system param's if someone ask's, the very first response, and usually alarmingly so, goes "Whoa! is that a typo, or do you really keep your SG that high?" Likewise, sometimes after orders are delivered, I'll get the same questions after my water has been tested, the customer often concerned their own testing equipment may be off, or if I do in fact keep my salinity "that high".




The answer is yes! And it's short and relatively simply story as to why, rooted solely in anecdotal observation and minimal reaction. Truth is, I have been running my salinity at roughly 1.028-1.029 for many years now, and my sps along with all of my fish have been loving it!

Essentially what happened (and this is exactly how I explain it to people) is that, when I'd fill orders, back in the old system, I'd sporadically pump water back into the system with the flip of a switch. Same thing went for skimmer cleaning. I'd flip that switch and replace an "unknown amount of water", with another "unknown amount of water". No measuring of any sort. Purely based on "feel" and whether my float valve was submerged or not. Mind you, I am not suggesting anyone follow my lead on that pursuit. Just explaining how I did it.

Well, one day many years ago, and it really was one of those "well one day" type instances, I couldn't help but notice that my SPS were looking good, and I mean really good, like that thick powdery looking flesh that I had never quite been able to achieve, in all my years. I saw deep coloration and bursting new growth at every node. It was remarkable! Over all things were just doing much better than I was generally used too. After simple rundown of some basic params, the only real blaring change from my norm of many years, was that rather than seeing 1.025 on my refracto it was closer to 1.027.


this simply will not do


So over time, with my rouge water replacement methods, my salinity had crept up. And upon this serendipitous revelation, seeing the apparent effects on my own tank inhabitants, I have been keeping it high ever since. Really, it's just that simple. I stumbled upon something that seemed to be a good thing, and I have been riding high ever since.

So what do you think? Anyone else keep there SG higher than the "norm"? And if so, do you think you have seen any improvement in coral appearance and over all vitality?

Or, am I just wasting good salt on a whim and an accidental coincidence?



I also run 1.028
I commercial fish Yellowtail Snapper in Key West. I’ll bring home water from the Atlantic Ocean for water changes, and almost every time that I check salinity it reads 1.028. I’ll bring some water tomorrow to see what it reads. Very interesting thread, thank you Adam for sharing

I accidentally was running my tank at 1.027 because of the calibration fluid had become more salty....assuming evaporation of water via diffusion thru the plastic bottle. And my observations were opposite! I had coral die-off on the undersides of my Acros. It went away once I fixed my issue.

Plus the extra cost of water changes is another negative. But if it works for you.....keep doing it! I put some Holy water into my system every so often...works great! Your mileage may vary :)

Interesting for sure, I wonder if alk was boosted or something like that in your case that caused the coral to respond poorly
