From 1.009 to 1.024...

I am slowly raising the salinity back up for a Stars and Stripes puffer who was in QT for a month. I was raising it about .003 a day the past three days. I was actually at the Public Aquarium here today and was talking to a biologist who told me that there is no need to raise the salinity so slow with a S&S Puffer because they naturally move in and out of brackish waters all the time when they swim in and out of estuaries and up rivers and back to the ocean. He was also talking about how many of them never end up going to the sea and stay in brackish waters their who lives and that many people keep them in 1.015 with no problems. Anyways, he recommended raising the SG about .002 every 2-3 hours in one day...I was just curious about what people thought about this? It makes a lot of sense to because I have acclimated my Green Spotted Puffers (also brackish to marine fish) from 1.008 to 1.026 in a matter of a day before when they came out of QT. They were fine. He did say that he would not do this with any true marine fish of course and would stick to .002-.003 a day max. Anyways, I have raised it by .006 tonight over 4 hours and hes fine...

by the way, he was a specialist in the puffer "area"...

Makes sense to mee too. Puffers are in a whole different category.

I am looking forward to the answer also

Yeah, Im wondering too. I am not in any way questioning the guy I spoke with today, as he is a very well trained biologist at one of the largest public aquariums on the westcoast, who specializes in puffers BUT I was more curious about what people thought...

I am expecting to hear about how wrong he is

I doubt that he is wrong considering that is his specialty and his job. Unless there is another marine biologist on here that want's to chime in I would trust his advice or if you aren't in a hurry just raise it a point or two a day.

Even if he is right (and he may very well be), I personally would not chance it. You went for a month at low salinity, I'd take the extra time to raise it more slowly. You're not really losing anything by taking your time. Swimming in and out of different salinity water more equates to sudden peaks and troughs for salinity. Something the cells of the animal may be equipped to handle. If you spend a lot of time at low salinity and suddenly go up a bunch over a short period of time, and then stay up, the cells may not have the proper ion pumps up or down regulated to deal with this. Again, maybe puffers do -- but I wouldn't chance it if it were my fish.

How are you going about raising your salinity?
