Beneficial Bacteria in the Water Column?

[cwschoon]

I am trying to explain to someone that there is very little beneficial bacteria in the water column and using old tank water will not assist the cycling process to any significant degree-rather unsuccessfully. Does anyone have any decent explanation, links that would explain this? This article does not exist anymore: https://www.advancedaquarist.com/2011/3/aafeature
Thanks.

Sorry but I'll disagree. All the benthic organisms, stuff grwoing on the substrate, in a reef system are manipulating the aurabiome, microbes in the water. Some of these microbes are beneficial for corals ans some are not.

Thanks for the reply. I was specifically referencing nitrifying bacteria and the cycle.

In that case, some likely is happening with the microbes in the water. It's happening within the coral holobiont too. A simple test to see how much is happening in the water is take a quart of aquarium water, test ammonia, drop in some ammonia then test hourly for 6-8 hours.

They would be much better off using new water but using a little of the old substrate..

If you're sticking strictly to just introducing nitrifying bacteria that's a very common way to start the cycle. But microbial stuff in reef ecosystems are far more complex than just converting inorganic nitrogen forms from ammonia to nitrite to nitrate. You have organic and particulate forms of nitrogen in the nitrogen cycle. Same goes for the phosphorus and carbon cycles. Of particular interest is Dissolved ORganic Carbon (DOC) as there are types (or species as is sometimes used by researchers) of DOC that is beneficial for corals and types of DOC that promotes pathogenic shifts int coral microbiomes. Innoculating a reef new reef system with the DOC as well as some of the microbial stuff that is beneficial for corals seems like a good idea to me. Obviously a donor system needs to be doing well but this technique is one I've been using for a couple decades and not only reduces nuisance algae in new ssytems but I've found it useful in remediating reef systems that have been stressed and have nuisance algae causing problems.

These are complex subjects and you might find these videos informative:

My only "goal" here, was to give good and simple information to someone who was entering the hobby and to counteract harmful, anecdotal information AND to ensure I was being accurate. My main point, was that using "old" water was not enough to cycle aquaria or at the very least, was not the most efficient way.

Yes, old water is just that, but unfortunately there are aquarium stores that continue to recommend this to beginning aquarists.
