    Hi,
    i bought 2 anemone crabs and a brittle star this weekend from 2 diff LFS and noticed that both had a salinity of 1016 and 1014, thats almost fresh water :) do u think that if i mentioned to them that they would get upset? i mean all their stock looks great, maybe they had an off day?

    i did my usual acclimitization using the drip method but took 5 hours to do it as my tank is at 1024-1025, thanks to jacques for taking my call when the panic set in.

    all are good now, but i think from now on it would be a good thing to get their params before one buys if they dont take offence to it

    It's mostly financial - salt is expensive, and they will keep the animals at the lowest salinity possible, just to save some money.

    It's not too bad in their setups, as the stock is "rotated" out of the shop pretty quickly, and therefore don't develop the issues associated with being kept in low salinity for a long time.

    Hypo-salinity (low salinity) is also a known cure / treatment for various parasites, including white spot, so keeping the fish at such a low salinity is also medicinal, reducing deaths in their tanks, before they can sell the fish...

    Good info Reef, I would panic as well.

    DallasG, When you were drip feeding it, did you just increase the water volume or did you also slowly drawout the LFS water

    thanks for the info hennie!

    silver, i usually keep about half the water they give, depending on the amount and what i bought, i then drip in about 3 times the amount, so in the ration of 3:1 and i do it over about 3-4 hours using a drip from the hospital

    Interesting topic.

    Hennie, how long could one QT a fish at a SG of 1.014? I thought around 1.018 was about the lowest we could go?

    On some of my fish setups i run a S.G of 1.015, but inverts and coral tanks are at 1.025

    i saw a big diff on health of the fish when i dropped my S.g of the fish only tanks...white spot seems to die off much quicker

    Or make it a practice to measure the water parameters in the bag before starting to drip. That way you are using the same measuring device/s for the holding water and your qt / dt tank. ie alliviate possible calibration differences.

    or just take your time and acclimatise properly over a long period of time. then Sg doesnt become such a big issue

    SG of 1014 is not a problem in fish only tanks even long term the main aspect of salinity is consistency. best to measure the water before starting to drip into the bag so you know how long to take. Raising the salinity must be done far more slowly than dropping it. i personally dont like keeping a fish in a bag for too long as it causes major stress in the fish's life.

    whats the best way then, as most of the time not enough water for a full QT, just mix a batch of water with the same SG and then slowly over a few days raise the QT SG to the DT?

    In my humble opinion - YES, that's the best way :thumbup:

    Yep I agree with Hennie, this is definitely the best way to acclimatise

    That would be ideal but so much hassle:whistling:I wonder how many reefers actually have QT tanks?

    thanks all, i have just setup my permanent QT tanks, as the sometimes 6 hour bag wait if needed can be stressful.

    I have made some filter bags, onion bags with 10 bioballs and ceramic rings in which i keep in my cupboard and will keep one in my sump to be seeded so when i need to QT in the future i can use that., that should keep my 2ft going for a week or so while acclimatising them, any suggestions? i have now set this up as my big system is almost fully cycled.

    would corals and inverts need the same process?
