What means fresh water dip, just RODI and for how long, than low salinity that is again slow brought up, or from RODI direct to SG 1025?

I agree great info. I’m at the point where I’ve never had a quarantine tank,just now where to put it. I’ve changed things around and really trying to build up my dt. I’m setting up a quarantine tank. I’ve gotten luck over the years with just adding fish to dt. Don’t want to take any more chances

I plan on setting up quarantine tank at same time as starting my DT .....so I’m confused about getting sponge from DT to start QT? My plan for QT is a 20G with HOB filter With carbon media a power jet , heater, thermometer and ammonia alert badge. So what do I have to do before adding a couple fish to QT tank?

"Empty the tank of water and put the sponge(s) from the filter back into your display tank sump"

That would seem to defeat the purpose of the quarantine. There might be a chance to transmit latent disease to the display tank.

Here’s my QT with its first real residents. I had to take the “permanent” damsels because the larger one was acting aggressive towards the flasher.
I wasn’t planning on removing them every time I put a new fish in.
Any ideas? I want it to be permanent in case I need to isolate a resident of the DT.

Just curious what the thoughts are on using a rubbermade trash can as a QT? I have one that I use to use to mix/store water in but have since gotten storage tanks for that.

Petco is having the dollar a gallon sale going on. I guess it's time for that cheap QT tank - plus I'm going to get start my sump build tank. Get new ones for the price of used!

This is a short guide on how to set up a quarantine tank for fish. Quarantining is a simple and easy way to help protect your display tank from diseases and parasites. This is also a great way to get your new acquisition eating frozen or prepared foods. A quarantine tank system is an individual system not connected to any other systems such as your display.
Here is what you will need:

  • 1 tank; 10g or more. A 20 long is good size for fish that swim a lot like angels, butterflies, tangs, etc. Use a tank appropriate for your size fish, a 10” tang is going to need more room than what a 20L can offer, use common sense.
  • 1 heater appropriately sized for your quarantine tank
  • 1 thermometer
  • 1 filter. I suggest getting an Aquaclear hang on back filter (I will be using this filter as reference in the guide). Purchase one appropriate for your size quarantine tank.
  • 2+ filter media; sponges and carbon
  • 1 lid or covering. Egg crate/light diffuser is fine.
  • 2+ PVC pipe parts (these are used as hiding places for the fish)
  • 1 light (does not need to be fancy, almost anything will do).
  • 1+ powerheads/water movers. Purchase one appropriate for your size tank, you do not want to be forcing the fish to the other side with too much flow.
  • 1 outlet timer (optional). To be used for your light.
  • 1 ammonia alert badge (optional)
  • 1 bottle of nitrifying bacteria (optional)
  • 1 set of BlueLife Instant Quarantine Dips (optional)
  • 1 sheet of aquarium backing (optional). This is used to cover the sides of the aquarium in case your tank is in a high people traffic area to protect the fish from being startled.
  • 1 emergency battery powered air pump (optional)
  • Separate set of miscellaneous equipment JUST for the quarantine tank (nets, cups, food, buckets, test vials, etc.)

Purchase your filter media in advance to setting up your quarantine. You can put the sponges in the sump of your display tank so they can start collecting beneficial nitrifying bacteria. After 4 weeks your sponge should have enough bacteria on it. You can now start setting up your quarantine tank.

You can fill your quarantine tank with water from your display, or you can fill with fresh saltwater. Start your heater and program it to match your display tank. Start up your hang on back (HOB) filter and insert 1 sponge into the filter. You can also start up your powerhead, but not necessary at this time. Now start adding in your thermometer, your ammonia alert badge and your PVC parts. Let the tank sit like this for 1 day.
After you have waited a day for the tank to sit, test the tank to see where the ammonia, nitrite, nitrate, pH levels are at. You need ammonia and nitrite to be ZERO. Nitrate can be present in numbers up into teens. pH should be in the normal pH range (7.8-8.3). If you have ammonia or nitrite you can add some liquid nitrifying bacteria (this can be purchased at fish stores, pet stores or on-line) and test again the next day, it may take a couple of days for the bacteria to do its work. Once you have all your parameters in check you can add a fish!

Purchase your new fishy friend from a reputable seller. When your fish gets home (or is delivered if you ordered on-line), float the bag the fish is in in the quarantine tank for 15-20 minutes so that the bag water temperature matches the tank temperature. Drip acclimate your fish for 1 hour. (If you choose to, you can now use the BlueLife Instant Quarantine Dips). And add your fish to the quarantine tank, with the lights out. After 5-6 hours you can turn the lights on and see how your new fish is doing. You can try feeding your fish the first day but it is common for them not to eat the first few days.
Once your fish is eating, swimming and looking great, quarantine can begin! I suggest quarantining for a MINIMUM of 30 days. You can quarantine as long as 6+ months. I personally do not medicate if the fish shows NO symptoms of any disease or parasite. Keep an eye on ammonia, nitrite and nitrate. Do water changes as needed, or weekly. Make sure to top off evaporated water with fresh water. Also after feeding your fish, try and remove as much uneaten food as possible as this can contribute to ammonia spikes.

When the quarantine is over, it is time to transfer the fish to your display tank. If any of the water parameters may be different from quarantine tank to display tank, I suggest performing a drip acclimation of at least 30 minutes to help the fish acclimate to the display tank. You can now shut down your quarantine tank until your next acquisition. Empty the tank of water and put the sponge(s) from the filter back into your display tank sump and turn off all equipment. You can also choose to keep the quarantine tank going without any fish in it. You will need to keep the bacteria alive by adding small amounts of food every few days. Perform water changes maybe once a month; you can use water from the display tank.

Some thing’s to keep in mind. If you use any equipment, like a net, in the quarantine tank, it either needs to become the quarantine tank net, or disinfected with a bleach solution. If you decide to add a fish to the quarantine tank while another fish is quarantining, the time restarts for the first fish. So even if fish 1 was in the quarantine tank for 29 days and you add fish 2 on day 29, fish 1 now needs to be quarantine for 30+ days again. You should NOT add rock or sand to your quarantine tank as parasites can hide in them. For some of the wrasses or jawfish you may need to add a small container with sand/rubble for them to sleep/burrow in. This sand should be discarded and NOT reused when the quarantine is done. If a fish dies while in quarantine, you should use a bleach solution on ALL of the equipment and tools used.

For a more in depth explanation and walk through to quarantining and medicating I STRONGLY suggest purchasing Mr. Saltwater Tank’s book on quarantining.

Here is my QT



I have gotten quite a few questions about rock. Here is a quote directly from Mr. Saltwater Tank’s Guide to Quarantining and Disease. “Quarantine tanks are very often bare bottom tanks (no sand) with only a couple of PVC pieces for fish to hide. The reason for the sparse surroundings is that medications can react with rock and sand, reducing the concentration of the medication and their effectiveness. Furthermore, certain diseases live at least part of their lives in the sand and rock. While your fish might enjoy the rock and sand, and these things will likely make them feel comfortable, we don’t recommend them for quarantine tanks that are being uses to treat fish.”
this is a great primer for anyone getting started and hope it does not fade into obscurity

I purchased a 40b with a Fiji cube drop in.
What type of filtration media would you recommend?
I was thinking bioballs.

My quarantine tank is set up pretty much as in the first post - it’s a 20-long sat right next to the main 300G through-wall tank in the “fish closet” (there’s not much space back there) side.

Due to the lack of space, there’s no NSW and RODI water tanks, they’re actually at the far end of the house, and I put in a couple of standpipes to transport the water all the way under the house to the fish closet. Because of the standpipe diameters, I use peristaltic pumps to automate my water-change and top-off, and I set it up so that the “waste” tank water is dumped into the QT instead of down the drain. In turn, the QT has a hole drilled in the side towards the top, so that it overflows into the drain.

There‘s nothing terribly wrong with the water coming out of the tank, the turnover is just to maintain the natural chemical balance, and it has the advantage of being identical to the tank water where the fish will (hopefully) end up… I change roughly (it’s measured in inches not volume) 5 gallons of water per day for ~10% system volume (including the sump etc) per week, so the water is reasonably “good”.

The QT has its own Energy Bar, and the Apex maintains it at 78 degrees F, there’s a Marineland Penguin 200 HOB filter running constantly to keep the water mixed at the same temp. I don’t have lights on it because it’s right next to the tank and gets the same (if less) light as the tank does.

I keep it running all the time because
  • Impulse purchases are a thing :) After checking compatibility etc.
  • I’ve used it as a hospital tank before now (after which ii gets cleared out, but refilling it from scratch doesn’t take too long)
  • It’s very low maintenance and “just works”. I don’t have much algae in my tank, so my QT stays pretty clean.

Here is my QT



I have gotten quite a few questions about rock. Here is a quote directly from Mr. Saltwater Tank’s Guide to Quarantining and Disease. “Quarantine tanks are very often bare bottom tanks (no sand) with only a couple of PVC pieces for fish to hide. The reason for the sparse surroundings is that medications can react with rock and sand, reducing the concentration of the medication and their effectiveness.

While your fish might enjoy the rock and sand, and these things will likely make them feel comfortable, we don’t recommend them for quarantine tanks that are being uses to treat fish.”
So just starting out, I've procured everything needed for my main tank, but wanted to get a head start in setting up a QT / Hospital tank (better safe than sorry).

So quick question, could i use a cheap tropical tank with built in light and filtration (say 20 liter) as a hospital tank? The reason i ask is mainly around the filtration, assuming i use media from my refugium?

Trying to save some money where i can as the initial outlays stack up fast when you're starting from scratch.
