Yes they would live in it. I have made my own and a lot name brand salts are basically synthetic. If you notice though adding fresh salt mix fish tend to not like it.Would a fish not live in permanently fresh synthetic seawater?
Let’s define a mature biofilm. Why do a fish or coral even need a biofilm?
"Microorganisms have been reported to induce settlement and metamorphosis in a wide range of marine invertebrate species. However, the primary cue reported for metamorphosis of coral larvae is calcareous coralline algae (CCA). Herein we report the community structure of developing coral reef biofilms and the potential role they play in triggering the metamorphosis of a scleractinian coral. Two-week-old biofilms induced metamorphosis in less than 10% of larvae, whereas metamorphosis increased significantly on older biofilms, with a maximum of 41% occurring on 8-week-old microbial films. There was a significant influence of depth in 4- and 8-week biofilms, with greater levels of metamorphosis occurring in response to shallow-water communities..."
"Habitat recognition and selective settlement by dispersive propagules greatly increases the post-settlement survival chances of sessile organisms. To better understand the key role some species can play in the structure of highly complex coral reef ecosystems, we compare the role of two independent, but sequential, processes: settlement choice and post-settlement survival. This study describes the chemical and physical recognition and ranking of specific settlement substrata by coral larvae. Several species of crustose coralline algae (CCA) are known to induce coral settlement; however they also employ physical and biological anti-settlement defense strategies that vary greatly in effectiveness. We examine the interactions between settling larvae of two common reef building coral species (Acropora tenuis and A. millepora) and five species of CCA (Neogoniolithon fosliei, Porolithon onkodes, Hydrolithon reinboldii, Titanoderma prototypum, and Lithoporella melobesioides) that co-occur on reef crests and slopes of the Great Barrier Reef, Australia. Distinct settlement patterns were observed when coral larvae were provided with a choice of settlement substrata. Settlement on the most preferred substratum, the CCA species T. prototypum, was 15 times higher than on N. fosliei, the least preferred substratum. The rates of postsettlement survival of the corals also varied between CCA species in response to their antisettlement strategies (shedding of surface cell layers, overgrowth, and potential chemical deterrents). Rates of larval settlement, post-settlement survival, and the sensitivity of larvae to chemical extracts of CCA were all positively correlated across the five species of CCA."
Nitrosomonas are AOBs, and a low AOB:NOB ratio have been suggested as an indicator of presence of complete ammonia oxidation (comammox) bacteria (Fowler et al., 2018). Nitrospira was previously thought to be nitrite oxidizing bacteria, however recent studies have found that some Nitrospira species are comammox bacteria and oxidize both ammonia and nitrite (van Kessel et al., 2015; Daims et al., 2015). Comammox Nitrospira have been found in biofilters treating waters with low concentration of ammonia, like RAS and ground water (van Kessel et al., 2015; Gülay et al., 2016).
Hi Lasse. I probably did get a little ambitious and excited with description on thread title. I could have done a much better job on title.That´s right but it is not because I use "new cycling methods". It is because someone have reinvent methods that we oldies have use since childhood and name that for new cycling science. The real new cycling methods for me - as an European - is the ones with huge amount of chemical ammonia in the start.

I love my ignore button in this instance.At first I thought he was talking to me lol - but I think its @LRT
Are you adware that you describe yourself the way I see you many times? and you are the only one I have been forced to ask not write in one of my threads? I could say - if you are sitting in the aquarium - do not throw stonesThis is how I'd handle it. I still peek at his responses lol and every 200 I get a very helpful one. not just now, but every 200
don't report anything the patterns will stand out. you get live tank entrants into your post, that wins.
credits to MN regarding watching out for nitrite in salinity-lowered quarantine systems that was honestly a good input. we need more of that, less pages and pages of sheer raw challenge for the sake of challenge.
Mn the way to balance your answers without causing permanent forum enemies is to limit the pages, and pages of heels dug in where you aren't contributing personal experience links, and maximize the times you're presenting ideas that come from personal experience and we can see the links for those aquarium works as well.
You don't need to go for pages, and pages, in a thread you didn't write. You dont write many threads, you respond to 98% as your post history. limit that, dont bring down other people's work thread you prevent your science from spreading by causing long term forum enemies by posting for pages, and pages, without one single personal experience verified input. its giving you free passage to literally harm potentially strong reference works. the harm is redirecting fuzz, purely opinion battles for 3-9 pages all focused on other people's threads. you dont submit pics, videos, charts, works, your own test tube setup pics + findings
you simply critique all other's posts. you've got to redirect that energy into a discovery mode I'd be interested to see what you find, but I won't know until 2022, late into that year.
Thanks, Lasse. I briefly saw mention of this process "comammox" elsewhere but missed the significance that it could account for some of what nitrification looks like in our systems.@taricha I come across an article that mention the probability of complete ammonia oxidation (comammox) in low ammonia loaded system (our aquariums is of that type - quote from the article. Can explain the findings from @AquaBiomics - at least he need to get the sequence from that species.
Me and MN have had very productive chats in the past and hope to continue to do so in future. No issues having constructive conversations and talking points on whatever we may disagree on which is not a whole lot tbh.This is how I'd handle it. I still peek at his responses lol and every 200 I get a very helpful one. not just now, but every 200

I know you disagree with most methods as a means to increase relevancy of measures at hand, but its just not ok to plant these stances in others threads with that much redirection energy. be working with other's reefs long enough that you have pattern examples for most issues you want to prove, one way or another and when twenty or thirty reefs are following a method you ascribe to, we'll have something to check out.
dont formulate an opinion right when you read someone's idea for the first time, then dig in heels. be already practiced on the matter and post those findings, showing prior study on the matter.
It would be awesome if you all could get into this more.Probably but the absence of biological molecules like colloids will - IMO - affect the mucous layer and the production of it. It will be a type of stress and energy demanding production of new mucous layer. These organic/biological molecules is always present in both natural fresh- and saltwater. In new started aquarium fish can be seen flashing and itching - a behavior that many people see as a sign of parasites - but - IMO - it can also be a sign of irritation in the mucous layer. I have often seen this behavior after huge WC.
I always prefer to have an amount of "old" water when I do fresh starts or i use Tetras Bactozym

Agreed. I'm not sure dry rock was invented when I first got into reefing honestly. Its probably going to take forever for me to break out of that old school mentality.As painful as it is on the wallet, the BEST way to cycle and set up a new tank is still adding the right amount of LR to establish everything.
I agree. Another poster seems to want to characterize me as some kind of monster. To me it’s funny how some people feel they have the right to demand how others behave. If anyone @taricha et Al want to send me a pm. I’m happy to read it. I never attempted to derail anything. Idon’t know the r2r policy but imho starting a thread doesn’t mean a person owns a thread. The fact is @LRT you and I agree about 95 percent of the theory and I have never felt nor hope I showed you personal animosity here. Maybe I’m on thw wrong forum. I thought discussion was rhe role.Me and MN have had very productive chats in the past and hope to continue to do so in future. No issues having constructive conversations and talking points on whatever we may disagree on which is not a whole lot tbh.
The ridicule and blatant putting down and disrespect from another is where i was mostly at.
Ignore is my champ on that though.
Very powerful tool haha
I think we are all good.I agree. Another poster seems to want to characterize me as some kind of monster. To me it’s funny how some people feel they have the right to demand how others behave.

Sorry to disappoint you again. In my first saltwater around 1978 - we had only dead coral skeleton - bleached and white My friend that was more into saltwater than I had a lot of dead skeletons from hard corals in his 120 G tankAgreed. I'm not sure dry rock was invented when I first got into reefing honestly
Hahaha Lasse I do appreciate you keeping me on point man! Steel hardens steel sir. Ive come to the conclusion in the other thread that im treading real lightly into the deeper waters with you. Not because you bring the heat with the big boys so eloquently. But because after you pointed that fact out. I took a look at your profile picture and instantly realized that you are a real life walking and breathing and living pirate.Sorry to disappoint you again.
