    quarantine temp

    My quarantine tank temp is down to 74 in the mornings never gets over 76. I feel this is ok
    since its a fish only system. Do you see a problem with that?

    I have heard cooler is better in quarantine. Slows down the fishes metabolism and cooler water holds more oxygen.
    Don't hate me cuz I'm a carnivore

    I’ve ran that low without issues. Not sure about the oxygen. I run air stones to try and hyper oxygenate my QT’s so I don’t worry to much about the oxygen levels. I know certain medications will < O2 in the water column.

    At one time I had an 8 diameter O2 cylinder (M tank) about 36 tall.

    I kinda got obsessed with oxygen diffusion and started to experiment with Gigantea anemones and IMO some of the most finicky fish around (Blue-Green Chromis).

    Hyper-oxygenated water seemed to really help both. It reduced the number of deaths with the chromis, but also helped the anemones stay more healthy during transport.

    The Chromis seem to always come in with Uronema which is unfortunate because nothing really helps much at that point.

    I need something like this for long transports...

    In a fish only QT tank running temps that low is not specifically harmful, however there some things to consider. Large temperature swings in aquariums do cause stress in fish, most can handle it but remember the temps on a reef are fairly consistent with little to no fluctuation from day to day. That said, two degrees is not usually considered a large swing for most, but more sensitive fish can be impacted to a larger degree. This causes stress, which can weaken their immune system. Once weakened it can leave the fish more susceptible to disease, infection, and possible increase sensitivity to the medicines we use to treat them. The end result of this could be longer QT times, or death of the fish. Another thing to note is the lower the water temperature is the longer it takes for parasites like ICH and Velvet to progress through it's life stages. Seeing as most of these parasites can only be killed while in the free swimming stage, if you run a lower water temp than the main tank, that means that it will be that much longer the fish will have to be in QT under treatment to ensure they are not infected. This also can lead to increased stress in larger fish if housed in a smaller QT tank.

    By running the QT temps at the same as the display, you reduce the potential for stress when acclimating, ensure the beneficial bacteria can effectively process the waste of the fish to reduce potential ammonia spikes, as well as potentially shorten the QT time as the parasite's life cycle is faster so the meds can do their thing. If done right you can shorten the QT time of a new fish to as little as 10 days in a cycled/medicated tank with a water temp at 78F vs say 14-20 days or longer at 74-76F .

    Lower temps can also lower the life cycle of bacteria

    quarantine tank is the least variable temp swing I have. Its not uncommon when its really cold or
    really hot to have a 5 degree temp swing in my big system/ during the summer I often start about
    77 and it up at 81/82 maybe even 83. Not much I can do about that in its the nature of 2900 gals
    in a steel bldg. Ive done extra insulation and reflective barrier to be as good as it is now. Guess its
    been a cool summer have only hit 82 at this point. Have 3 air conditioners but only running 2 at this
    point. turn the third on when tank temp hits 81.
    have heard of big temp changes being a problem but by me never seen it cause a problem. Who
    knows, my sps might look better if I could cut out the swings.

    Back to this topic...

    Based on what I know warmer is better. Most of the parasites can't resist above 80 temp. My qt in the garage gets to 83 (with a small chiller set to 81 and garage has two windows).

    In a fish only system most people raise temp above 80 to kill parasites such as ick.

    Hey imagine garage reef tanks-it easily gets to 83-84f in Texas with a chiller.
