At what point does a tank not become new/is established? Because all I keep hearing/seeing from multiple people is “omg your tank is so new or it’s going to crash etc.” and not necessarily about me at least now.

I would say 6 months is established, usually around a year to two years to be fully matured from a bare tankAt what point does a tank not become new/is established?

It's a continuum. Over the first month or two, 2 parts of nitrogen cycle are established -converting ammonia to nitrite, and nitrite to nitrate. It can take many months (depending on a lot of factors) to establish denitrifying which is converting nitrate to nitrogen gas. A fourth part of the nitrogen cycle is nitrogen fixing, which is more complicated than I can explain here.At what point does a tank not become new/is established?

Then there is the "algae cycle". Most tanks started with most or all dry rock will go through various stages of different nuisance algaes over the next 6-12 months. Diatoms, green algae, dinos, and cyano can be seen during this time. The appearance of diatoms during the cycling phase of a tank is absolutely normal, and you need not take any countermeasures. As a rule, the diatoms are crowded out by green algae a few weeks later, which is crowded out by other algaes, and so on.
During this first year or so, other bacteria and archaea also become established in the system and help form what we usually think of as a "mature" tank.

That can be a open ended question. But imo a tank never stops maturing. It’s an ecosystem in itself and the longer it goes on the more biodiversity you have. But just because it’s old doesn’t mean it won’t have its own problems. Apparently there is “old tank syndrome” but I don’t know too much about that. Older tanks with owners who are consistent in their methods have an ecosystem that over time has adapted to its environment and creates stability. Things always change but stay the same. It’s kind of a paradox.At what point does a tank not become new/is established?

Don't worry it'll pass...how old is your tank?I am in the algae/ugly stage!![]()
I know looking forward to it! Almost 2 months.Don't worry it'll pass...how old is your tank?
Yes, that's a good time to start meditating, lol! It can be hard to not add a bunch of coral (fish are generally ok, if you go slowly so the nitrifying bacteria can keep up with the increased bioload) that might be adversely affected by the different algaes.I am in the algae/ugly stage!![]()
Yeah, that's expected...how are the rest of your fish btw? I remember you posted about having ich on one of your fishI know looking forward to it! Almost 2 months.
Great!Yeah, that's expected...how are the rest of your fish btw? I remember you posted about having ich on one of your fish
I believe it was velvet though that flared up from bringing the fish home. I was going to quarantine the rest of them but then I realized I didn’t want to stress them out unnecessarily so now I’m just going to wait a few months before adding new fish and have been dosing vitamins.Check out this article https://www.reef2reef.com/ams/the-other-way-to-run-a-reef-tank-no-quarantine.573/Great!I believe it was velvet though that flared up from bringing the fish home.

Good to hear! I doubt it was velvet though because of just how agressive it is... usually when one fish gets it it spreads extremely quickly and can kill half your tank in 24 hours...ich on the other hand isn't so fast...just to be safe though if you happen to notice any weird behavior or spots on the others post ASAP because time is one thing you don't have if it does happen to be velvet...you seem to be staying pretty on top of things by asking questions on here!Great!I believe it was velvet though that flared up from bringing the fish home.

Yes definitely. I will be quarantining and treating them if I do but it’s been almost a week and no signs/symptoms and I’m thinking/hoping it’s going to stay that way.Good to hear!

Oh it’s Paul B lol who is clearly one of the most successful people in this hobby and has the oldest personal reef tank on here.Check out this article https://www.reef2reef.com/ams/the-other-way-to-run-a-reef-tank-no-quarantine.573/
not all people agree with this method but I think it has some good insights
