Also, I started out not quarantining and I wound up having a fish that had ich and another with velvet, took the whole tank out..is there a way to avoid that without quarantining? I have 150gal system
I fully understand how having that experience would cause you to question whether executing quarantine is the right thing to do. Please allow me to walk you through some information that will help you have high levels of success in keeping fish.
The tldr; follow the official quarantine protocol:

1. Ignore "Pseudo-science" and focus on true "Science"
Pseudo-science is the improper application of limited scientific facts to justify actions that are counter to the broadly accepted beliefs of the scientific community. Pseudo-science frequently takes advantage of people's desire to have things fast and easy. Pseudo-science supports its positions based on flawed logic, such as "I've been doing it like this forever and never had a problem" or citing questionable research from organizations or researchers who are not credible. Pseudo-science frequently uses a single observation as justification for a position.
True Science is based on scholarly research conducted by credible organizations and globally recognized leaders in the field. True science is thorough and complete. True science leverages "experimental design" and repeated tests with statistical validation. True science provides actual proof!
2. "Post Hoc Ergo Proctor Hoc" - Don't assume, do an investigation to understand
If you had the pleasure of taking a philosophy class or methods of research class in college, you most likely heard this famous Latin phrase. This phrase is intended to tell people not to assume that because an outcome occurred after an action or observation, do not attribute that outcome to the action. Common examples of this thinking are believing "quarantining killed my fish" or "quarantining doesn't work because after quarantine, my fish still got ich when I put it in my display." What you will find when you investigate is that the root cause was not the quarantine but something else, usually an unfortunate oversight that can be corrected.
3. If You are Patient, You Will Have Success
Rome was not built in a day. One of the pillars of long-lasting success in the hobby is being patient. Rushing to put that new fish into your display will be the reason you struggle to keep your fish alive. As you will see in the
official Reef 2 Reef Quarantine Protocol, you need to do a 30-day medicated quarantine to have success in quarantine. Wanting to see your new fish in your display and having to watch in a hidden bare aquarium for 30-days is one of the hardest things in this hobby, which probably explains why people skip or skimp on this critical step. Rest assured in the knowledge that executing that quarantine process will maximize the life of your new fish and all of your other fish in your display by preventing the introduction of pathogens that wipe out your fish. Take it from someone who lost over $5K in fish from not being patient.
4. Be Prepared
In my opinion, based on my personal observations, the most common reason people fail at quarantine is not being prepared. Whether it is not having a suitable quarantine tank, not having a copper test kit, not having proper filtration, using the wrong medicines, or whatever. People typically fail because they are not prepared. Being prepared is much easier than you may realize. The official Reef 2 Reef Quarantine Protocol lists the equipment needed to execute a basic quarantine of a new fish. One of the situations I find most people are not prepared for is a breakthrough outbreak in their display. An outbreak requires removing ALL fish from the display, placing them in a 30-day medicated quarantine, and keeping the display fallow for at least 45 days ( I personally like 60 days, but the experts agree 45 days is effective).
Things to consider when preparing for an outbreak are:
- How will I catch all my fish?
- Do I have an emergency quarantine system large enough for ALL my fish
- How can I create the space to store all my fish in a separate location from my display
- What type of mechanical filtration will I need to support ALL my fish at once
- How do I fully establish biological filtration on day one
I had the misfortune of needing to execute my emergency quarantine plan because of a bad seam in my aquarium that required immediate tank replacement. While I didn't have all the equipment I needed on hand, I had a written plan of what I would do if I needed to do the extreme. I used four large plastic storage bins/totes from Home Depot as mini homes for my fish. I separated the fish in a way to avoid aggression during this long-term temporary housing. I had eight large sponge filters and bought a large 35-watt piston drive air pump to supply ample gas exchange and current through the sponge filters.
One of the most important parts of my plan was ensuring day one biological filtration. I knew I was going to spread my abundance of ceramic bio media and rock across the multiple bins and provide a boost through Fritz Turbo Start 900. IMHO, poor ammonia management kills more fish in quarantine than anything else.
5. Being Pennywise Kills Fish
I see people frequently say, "I can't afford to buy the equipment to quarantine". These same people have dozens of $200 frags and fish that are $500 each. I have three dedicated quarantine systems, not including my emergency ALL fish system. All the equipment, medications, and Hanna test kit cost less than $105. My emergency cost $127. Being willing to spend this money provides a huge benefit!
6. Follow the True Experts
In my professional life, whenever I am looking to conduct any activity, I always start by understanding what the best in the world does, then I try to understand the components of what they do and figure out how I can implement it on a smaller scale. If you look at the processes followed by the large public aquariums, they all follow a thorough medicated quarantine process. The Reef 2 Reef community is fortunate to have Jay Hemdal, who has decades of experience running large public aquariums and has written a quarantine process derived from the steps they followed, scaled down and simplified for the home aquarist. We literally have access to a quarantine protocol derived from the best practices of the world's leading aquarists and marine biologists. This protocol provides 99.9% effectiveness.
I apologize for the long post, but I feel it is important to be thorough to avoid confusion. If you listen to the advice of people like Jay,
@vetteguy53081, and
@MnFish1 while avoiding the misinformation from people who go against proven science, you will have success!
