Both IMO but I know some older people that act like children so some people never mature which means the tank most likely will not either.
The best way I have found to gain stability is to pick a method and follow that path not straying to try other methods after a month or two because results aren't what the person desires. I was just like many when I started off. I read about this and that and he said she said so I would try this and that. Everything was a mess for the first could of years. My most succesful tank to date finally came to be when I chose a path and stuck with it. I chose simple. That tank ran on water changes and kalk but it didn't happen in 6 months. This was shortly before to broke the tank down after 7years
Most of what was in that tank is here now. Again I chose simple. Cryptic fuge with an ATS in the sump, 2 part manually dosed and an occasional water change. This tank was filled in March and is doing pretty well. These are opposite ends of the tank
IME live rock really helps to bring stability to a young tank sooner.
This is the sump of the tank above
Another example started Feb 2023 and just started coming together at the 1 year mark. Simple as well. Very minimal water changes just to clean detritus. I dose all for reef and have a fleece roller.
But if course we can't have success without failure. This tank has been running 4-5 years and was awesome but I got bored and changed out the rock and added new dry rock. I got a bunch of gha so I used Flux rx to get rid of it. Then I got cyano so I used chemi clean. Then the gha returned so I rinse and repeat. I decided the gha wasn't as bad as the cyano so I've been dealing with that for the last 14 months all because I wanted to change things up.
One of many manually cleanings, fun stuff. I'm tempted to tear it down and start over but feel the need to keep on. Maybe it's my penace for straying from the path I had chosen
Sorry this ended up being longer than expected and I ramble but maybe some one starting off can take something positive away.
