FW vs SW bacteria

[rtgordon]

Are they the same? I was told that if I used my HOB w/d from my established FW tank that it wouldn't cycle when I replaced the FW with SW if I put fish in there. I even went so far as to keep the filter running while I converted the tank. It did go through a small cycle ( i realized that it was cycling after I added the small dwarf fuzzy and a Kole Tang). The fuzzy was fine, but the kole tang didn't make it (It didn't look so great when I took it home anyway).

Anyway, what is the definitive word? Are the bacteria different?

Thanks!

From my understanding, bacteria is bacteria. Spanky or one of the Think Tankers may set me straight, though.

I get different answers from different people. I suppose the cycle was from the addition of the LR, but the filter should have been able to process ammonia as it was an established FW tank.

aint no expert.. but in my science world bacteria can take many forms and live differently...my guess would be that there is a difference from bacteria living in SALT water..but that is only mine guess...

No, they are not the same bacteria. Dr.Tom Hovanec, Chief Science Officer of Aquaria Inc., of Marineland Labs/Aquarium Systems did his Ph.D work on ID'ing the species of bacteria in seawaer aquariums. The numbmer/types of different species of bacteria and what they do in the ocens is almost an endless list. For a full review, if one was interested;

Dr. Timothy A. Hovanec is the Chief Science Officer of Marineland. After studying limnology at Uppsala University in Sweden, Dr. Hovanec graduated from San Diego State University with a B.S. in Biology and a M.S. in Biology.
Dr. Hovanec earned his Ph.D. in Ecology, Evolution and Marine Biology at the University of California, Santa Barbara, where he investigated the phylogenetics of nitrifying bacteria in aquaria and Mono Lake, California. Dr. Hovanec was the first to demonstrate that bacteria of the phylum Nitrospira were the active nitrite-oxidizing bacteria in aquatic systems such as aquaria. His work on nitrifying bacteria has lead to the discovery of many new species of nitrifying bacteria in freshwater and saltwater systems and the granting of several U.S. and foreign patents, with additional patents pending. He has also conducted much research on topics such as ammonia excretion and toxicity in aquatic organisms, bio-filtration systems design, and fish feed formulations.
At Marineland, Dr. Hovanec is in charge of the biology, chemistry and microbial ecology laboratories that comprise Marineland Labs. He is also responsible for overseeing the quality control of such products as Instant OceanŽ sea salt and BioSpiraŽ nitrifying bacteria.

Dr. Hovanec has authored numerous scientific papers in aquatic microbial ecology, and in public aquaria and aquaculture fields, and he writes popular articles on tropical fish for several magazines (many of which can be found at www.marinelandlabs.com). He has been an invited speaker and contributing author at several domestic and international conferences. He is the editor of SeaScopeŽ magazine and a member of many scientific organizations. His past positions include a U.S. Peace Corps volunteer in the Philippines, university research assistant, biologist and manager at an intensive striped bass aquaculture facility and consultant on various aquaculture projects.

thanks Boomer i will take a look at the lonk later on myself.. be neat to read and see some diff. types than i am use to seeing now

Thanks for the replies... There are no commonalities? On the bottled bacteria, it says Freshwater or Saltwater.
