The Puffer Forum

I doubt the SG at the shop will be very high. Do you know what it is?

I am curious about the answer to this because when I get to move onto a puff bigger than my dwarves it will most likely go into a current fw tank, and since I haven't ruled out brackish puffs that is of interest to me.

I believe the changeover from FW-SW bacteria happens around 1.010. I'd go no higher than 1.008 to be sure.

Thanks for the information....do you have any suggestions on books and/or articles that go further into detail on the fw/bw/sw levels and how they affect bacteria? Something I will need to completely understand BEFORE I consider the possibility of a bw puff. I don't want to make any mistakes when the time comes that could have been avoided. All of the information I have found so far tells you how to bring the salinity up etc, but haven't seen anything mentioned that a different bacteria needs to culture for the higher salinity levels. If I am understanding correctly....once you get to a certain level of salinity your tank needs to re-cyle to establish the sw bacteria...this sounds like it could be bad going from a new puff in low brackish that needs to gradually be changed over to higher brackish or marine.

Thanks Boxermom...I have added that page to my favorites to be able to read and study for when the time comes. I am sure there will still be plenty of questions from me still in the future.
