I know is important, but I'm not smart enough to understand

Ok, it's this article. Too many words though, arrgggh.

i can read a little bit ....what are you having trouble with?
try sounding it out that always helps......lol

Just summarize it, I'm a 12 pack in and still not making sense.

I would need some adderall to read all that, but did you see the bacteria levels in the mangrove estuary? I wonder if the mangroves themselves are at least in part responsible, or if they are doing well there as a result.

Wow it is early for that article, I barely got past the title. Need coffee...

I'm not to that part yet. I did read the summary and cliffs notes though....ok just the summary and comments.

Wow, that's like the medical journal articles I have to read. Basically: bacteria good, carbon dosing can increase bacteria population, skimming may remove bacteria needed in the water column. Dosing only good if bacteria is in the water column and not film. Bacteria nutrient needs in the home aquarium environment are unknown. High bacteria counts are good for some corals and low bacteria counts are good for other corals. Basically bacteria counts in marine water columns throughout the world vary along with each home aquarium depending on filtration and dosing methods. In short if your corals grow and look nice you are doing something right. To add to this article I watched a show on NatGeo last week about caulerpa and how it was taking over in the mediterranean sea. It was interesting in the fact that scientists took strands of caulerpa from around the world and could not get a match for the kind in the mediterranean sea that was covering the seabed and killing anything else that grew. Finally they took a dna test from a strand from a home aquarium and got a perfect match. Somehow the caulerpa in the home aquarium evolved and changed its dna strand to survive in a different ennvironment. My point being do our corals do the same? I honestly don't know but it seems funny how certain zoas melt forever in home aquariums then someone gets lucky and gets one that survives and then it starts growing and does fine. Does this have to do with the fact someones home aquqrium is identical to the marine water column the coral came from so it could survive, or did the coral actually go through a change itself? Got a feeling we will never know.

Interesting observations with the latter part. That's like the giant hammer in neptunes. It was growing for so long in crappy water that when they cleaned up the water, it wasn't used to the sudden change and wasn't nearly as big afterwards. However with the change in water chemistry, does that mean that the longer we acclimate our coral, the better chance it'll have at surviving in our systems?

Interesting stuff thanks for the breakdown I read the whole article also and I figure If all my fish are healthy my corals look good I wont change a thing. What I thought was kinda of cool is that with no mechanical filtration the bacteria thrived in the water column for their one experiment. Makes sense that if you leave the water undisturbed the bacteria can do its thing a little better. The whole carbon thing kinda sucks, if I read the article correctly they say that carbon does nothing to export bacteria from the water column hmmm From what I seen a filter sock full of fresh carbon sure does make the water crystal clear in my reef tank but I guess thats all it does

What I take out of it is that skimmed tanks are way deficient in bacteria from natural sea water. And the possibility exists that skimming creates hard selection pressures that benefit bacteria that aren't skimmed out of the water. Vodka dosing with heavy skimming to remove a bacterial bloom likely pushes the selection pressure even more. Sanjay and the others wonder if skewing the bacterial populations this way might contribute to conditions like old-tank syndrome.

Be all that as it may, tanks like mine without skimming have normal bacterial levels (as compared to seawater) but likely have high DOC counts. They are also crap for growing stony corals but soft corals do fine (but we all knew that).
