Moving a saltwater aquarium

There comes a point in every hobbyists life when you’ll need to move your saltwater aquarium. This happened to me recently. I had to moved my tank a few hours away. Moving a saltwater aquarium is far more complex than moving a freshwater and significant care needs to be taken in order to avoid or minimize loss of fish, corals and other livestock.
I did great deal of research prior to moving my 75g tank including placing a post over on the 3reef forums to obtain advice from the folks over their that I’ve come to completely rely on. What follows below is the process I used to move my tank. There are many different ways and I am in no way guaranteeing my will work for you. Fortunately it was pretty successful for me. I only lost 2 corals and is purely my fault. You’ll see why below.
Equipment needed to move your saltwater aquarium
Here’s what you’ll need to move your saltwater tank, at least with my process:
- 5 Gallon buckets with lids
- Battery Air Pumps
- Submersible Heaters
- A large truck, SUV, or trailer - assuming you have a large tank
Obviously, you’ll need one bucket for each 5 gallons of water. You’ll need one battery powered pump for each 5 gallon bucket that will contain fish, corals or other livestock.
A few days before your move
Go ahead and get your supplies and equipment together. It’s better to have a few extra buckets than not enough. Also, consider whether you plan to remove your sand bed or leave it in the tank. For anything more than a 75 gallon tank, I would strongly advise removing your sand bed. The tank is heavy enough without the additional weight of the wet sand.
Here are just a few things to plan out and consider:
- Have some friends available to help you life the aquarium and stand. Trust me, it’s not worth the risk of trying to handle it yourself. One slip and well…you know the rest.
- Get plenty of batteries for your pumps. I ran mine for about 24 hours on a single set of batteries, but I had plenty of extras just in case.
- Write down (or print this article) so that you have everything all planned out step by step. Remember, the longer your fish are out of the tank the more at risk they are of not making it.
- Plan things out in advance. Think through how you are going to transport the fish, tank, lights, pumps, filters, skimmers, and buckets. I rented a U-haul trailer just to carry my tank and fish.
- Find or buy a few plastic containers to carry your equipment in. Boxes work well for dry goods, but you’ll want the plastic containers for any of your wet equipment.
- Packing supplies. I used bubble wrap and moving blankets to wrap my lights, filters, cooling fans, etc. to protect them when we move.
The day of the move
We had a moving company move us, but if you are moving yourself I would strongly advise that you get some friends and family to help you move. Your main job and focus should be on the aquarium. Before starting to actually disassemble the aquarium, go ahead and pack up all of your dry goods and anything not needed to keep the aquarium running.
You’ll want to wait until the very last minute to start the actual process of disassembling the aquarium. Make sure you have all of your supplies handy: buckets nearby, a siphon tube or pump, lots of towels and a helper. Once your ready, here’s the steps I did when I moved my tank:
- Turn off all of your lights, unplug and remove them. I have an “all in one” light fixture, so I wrapped mine up in a moving blanket to protect them.
- turn of your heater(s). Don’t remove them yet! Let them cool off for a bit before removing them. Place them in one of the plastic containers as well.
- Turn off all of your filter equipment and pumps. Drain it and place it in one of the plastic storage containers.
- Now you’ll start draining the water. If you have live rock, fill up your buckets half way then add live rock until the water is a few inches from the top.
- Continuing this process until either all of the live rock is removed. If you don’t have live rock, once you get to about 6″ of water left, stop
- With the live rock out of the way and a minimal amount of water, now’s time to catch the fish. Using a net, catch the fish and place them in a bucket of water. Be sure to place your fish based on their compatibility with other. I put my clowns and their anenome in one bucket, my other fish in another, and my inverts in a 3rd along with my corals. As soon as your fish, corals and inverts are in the buckets, hook up your battery powered air pumps. Also add the submersible heaters. Don’t turn them on yet though. Wait about 15 minutes.
- Drain the remaining water. If you are going to remove the sand bed or substrate, go ahead and scoop it out into it’s own buckets.
- Place lids on all of the buckets but the ones with your livestock. For those, cut or drill a hole in the lid for the airline to go through. Cut another hole to allow the air in the bucket to vent out as well. Trust me, I learned this one the hard way!
- Now it’s time to load up. I’d recommend wrapping the aquarium with a blanket to protect it.
As I said, I rented a U-Haul trailer. I loaded the aquarium loaded with by sand bed into the trailer along with the stand. I then placed the buckets of water into the trailer as well along with my dry goods and the plastic containers. I put the fish up in my truck with me. It was a bit cool that day and I wanted to keep them as warm as possible. I also had my kids riding with me to keep an eye on them.
Setting your tank back up after moving
We closed on our new home at 10:00 the next morning. Overnight the fish and live stock stayed with me. We went straight from the closing to our new home where I immediately began setting up the tank. Here’s the steps I followed:
- Set-up the stand and tank
- Began adding water. This turned out to be a bit of a problem for me. It had gotten colder overnight than I had anticipated. In hindsight, I should have placed a portable heater in the trailer overnight to keep the water temperature in the bucket nice and warm. The water I was poring into the tank was about 40 degrees. I immediately placed all of the heaters I had in the tank, waited 15 minutes and turned them on as I continued to pour the water in. As soon as the water level was high enough, I installed my pumps, filter, and protein skimmer. The water was REALLY cloudy.
- I also started adding the live rock while pouring in the water was well. With the cloudy water I couldn’t see to place it, so I just laid it in there.
- Once all of the rock was in, I topped the tank off with the remaining water.
- I then installed my lights and immediately turned on my Metal Halides to assist with warming up the water
- Once the water was up to temperature and had cleared up some, I added my fish and other livestock to the tank.
Things I would do different next time
Overall the move went very well. I did have some die off, but as I said earlier due to a few mistakes I made. So let me overview those:
- I didn’t plan well for the overnight cool temperatures and as a result it took my water a good 4-5 hours to warm up. Fortunately I had the extra heaters, otherwise it would have been even longer than that. As a result of the cold temperatures, I had a bit of die off on my live rock. Not bad, but more than I wanted. I wanted zero!
- I placed my “hard corals” in a bucket of their own that wasn’t heated. As a result I lost both of them. I should have treated them just like the the rest of my livestock.
- To make the move easier, I kept my sand bed in the tank. I should have removed it and placed it in buckets and washed it before putting it back into the tank. The sand bed was filthy. While washing it out probably would have caused a small cycle, it would have been worth it.
The tanks doing great. I’ve had a bit of an algae bloom in the past few weeks, but I expected that with the bit of die off I had. My nitrates are up and feeding the algae. I’m doing frequent water changes until the levels come down.
Have you ever moved your tank? What process did you use? Did you have any die off?

I’ve had 2 false 
Upon returning we were greeted at the door with a loud “Dad! The clown fish are in the Anemone!!!!”. What??? No way!!! I rushed to the tank and sure enough both clowns were in the anemone. The female in particular. She was having a blast, nuzzling it, rubbing herself all around in it and cleaning it out. The male kept trying, but she would push him out. He was a persistent little guy though and she finally let him in.
