“What skills took you longest to learn in reef aquarium keeping?”

[Frank987]

I’m curious what parts of reef aquarium keeping took you the longest to really understand.
For me, the biggest learning curve seems to be things like maintaining stable water parameters, understanding coral needs, and knowing how to react when something suddenly looks off in the tank. It feels like there’s a lot you only learn through experience, mistakes, and advice from other hobbyists.
What skills or knowledge areas took you the most time to feel confident in water chemistry, equipment setup, livestock selection, algae control, or something else? Any tips that helped you learn faster?

Chasing numbers , we chase what the beautiful tanks that reefers have and try to replicate . And we are always changing things to fast. I now check my parameters and look at my corals and if their polyps are out I don’t change anything just test weekly
and keep my numbers consistent . Really learned how to keep things simple .
Chasing equipment trends . Buying everything you think you need for example you got a skimmer that’s doing its thing and a new one comes out and one feels he needs to get the new skimmer, if is working save until it breaks because trying to sell it you’re gonna get nothing . Use the money on corals or fish ,
For me that’s it I have no problem testing, water changes , cleaning parts, waiting things out ( patience ) I guess after you lose a lot you learn and become more careful. But most of all keeping my hands out off the tank

That’s solid advice. I think “keeping things simple” and not chasing numbers or equipment is one of the hardest lessons for most of us to learn.
For me, patience and stability took the longest too especially realizing that constantly adjusting parameters usually makes things worse, not better. Watching coral behavior instead of reacting to every test result was a big mindset shift.
What helped me improve faster was keeping notes of test results, coral reactions, and any changes I made. Over time it became easier to spot patterns and avoid unnecessary tweaks. I also try to read guides or learning resources on reef tank stability and parameter management when I want to understand something deeper.
Do you think beginners struggle more with over-adjusting the tank, or with choosing the right equipment in the first place?

Patience. I had tanks for about 4 years and was always messing with them to "fix things". Had to move to a town about an hour and a half away but wasn't able to move my systems right away. For six months I was only able to swing by on weekends to check on them and about the middle of the 2nd month I realized they were all looking better.

When you first start it’s difficult to keep yourself from trying all these different things that you don’t fully understand in an attempt to take the best care of your tank. The best approach I have found was to get really good at the basics and slowly introduce new things as necessary. Master your maintenance, easier corals/fish, and water parameters. Once you’ve gotten good at those set up your automated major elements dosing, maybe venture into some of the more important trace elements, fine tune things for some more difficult livestock, and so on. Having a thorough understanding of foundational reefing principles through research and experience gives you the tools to not only troubleshoot a variety of issues you may come across but also ensures you are ready to take your reef game to the next level.

It’s not only beginners it is advanced hobbyists too , advance hobbyists think because they have more years it should be easier and they understand more but believe it or not too much info can also hurt more than not knowing. Being new you might adjust more but sometimes being new your learning curve is different. It more about paying attention to your tank and taking note so when something goes wrong you can pinpoint where it started, and start to fix it.
Funny little story I met a person at a reef shop and we exchanged numbers he wanted to get into reefing . He was impressed with my tank . I helped him set one up . Told him to be patient and stop listening to everyone especially the pet shop employees ( the ones that really don’t have a clue, they just work there) and within 8-10 months he had a beautiful tank with sps and it was awesome I couldn’t believe the success he was having as a newbie. He said I owe it all to you. Colors, unbelievable growth ,polyp extension you name it he had it . as a seasoned reefer I was jealous. I said now leave it alone and just watch .enjoy it and do the necessary water changes and monitor. Then he took a turn and started changing things adding fish that weren’t capable, changing chemical,getting highend corals then he hit me with the I want an ULTRA LOW NUTRIENT SYSTEM , I said where are you getting this information.he said I’ve been doing my research and follow lots of threads , talking to other reefers. I said leave well enough alone.1 month later everything started to go wrong and he listened to the shop and got everything they suggested to help that didn’t work, his amazing tank crashed. I asked him one question! WHAT HAPPENED! He said he didn’t know . When did it start happening! No answer . Then he started to tell me things he started doing without me knowing and listening to others. After everything he said , I SHOULD HAVE KEPT DOING WHAT WAS WORKING THAT YOU SHOWED ME . We reefers made lots of mistakes and errors already so that the new generation can do better than we did ( I started when we used undergravel filters ….lol ) he let not being content destroy him, new gadgets and new chemicals he felt he knew everything, He never was able to get another tank to flourish so he got rid of everything and quit the hobby Sometimes it’s not the advanced equipment and chemicals it’s just the BASICs of starting, maintaining with husbandry and learning with patience and note taking . So a newbie can have just as much success as a seasoned reefer if things are done right!!!!!!
Good luck and happy reefing
