    Hi I have just finished my tests on my 180lt reef tank using Red Sea Marine care test kit and Reef foundation Pro test kit.

    I would welcome some help with the translation especially on my Mg and KH results.

    Many thanks.

    NH3/4 ~ 0
    NO3 ~ 5
    NO2 ~ 0
    PH ~ 8.1
    Mg ~ 0.61/1220
    Ca ~ 0.77/385
    KH ~ 0.99/1385/4.95

    MG 1220ppm a touch low for a reef tank
    CA 385 again a touch low
    Dkh if 0.99 is meq/l your Dkh is 2.77 which is very low. I'm guessing you got your decimal place mixed up with the 4.95 should it have been 49.5ppm?

    Hi Warby and thanks for your swift response. Im now totally confused. Ive added a picture of the results card i use. I think ive put my results in the wrong order so have written them again but in the same order as on the card ive added below.

    Many thanks. Paul.

    Titrant used 0.99ml. Alkalinity Meq/L 4.95. dKH 13.85

    That makes more sense your dkh is high ideally between 8 and 12 mine sits at 9.3.

    can you double check your salinity

    since you are low across the board it may be your salinity is too low

    what do you measure with ?

    when was it calibrated last ?

    Hi again and thanks for the help.

    I use a Refractometer which i have just checked and its calibrated on zero. I checked the salinity and its at 1.025 and at a temperature of 26.6.

    I water change every two weeks with water bought from my local marine shop and top up in between.

    My tank is in its infancy relatively speaking, im in my 10th month. My tank holds 180lt and i run a external filter and protein skimmer. I have around 7kg of live rock, 4 Chromis, A sailfin, a yellow/brown tang, a pink clown and a pipe fish. Also a small finger leather, small Zoa and a orange lollipop sponge


    If these are ok is there anything i can do to change the low readings?

    OK

    Sounds like the shop has a basic salt
    Which is fine for fish

    Assuming this is the case

    By the RO water and mix your own salt

    Do you have a TDS pen ?

    It good to test the RO water ideally it should be 0TDS

    Total
    Desolved solids

    Some LFS are not, a good one will be able to show you the purity of the water and will understand why you ask

    Does your lfs do 2 types of salt water? Mine does normal salt and reef salt (reef salt has elevated mg ca dkh e.t.c.) my lfs uses reef crystals for there reef salt.

    Hi, I've just completed several TDS tests on RO water i collected this morning from my local marine shop to use as top up and its reading 102ppm.

    I have just spoken to them and they only offer RO or salted. No water specifically for reef tanks.

    Do i need to find a new supplier?

    Cheers

    Unless the container was contaminated
    That TDS is awful !!!

    Personally I would contact [MENTION=11655]LittleOcean[/MENTION]

    And make my own RO and purchase a suitable salt

    If the container had salt water in before you could get a high reading

    Hi,

    I have 4 25lt containers 2 for salt water 2 for RO. I mark them so no cross contamination can occur.

    Is it the quality of the water that is causing my low testing results?

    I will contact Toby to help with my own unit.

    Many thanks for the invaluable advice.

    Thanks. Paul

    I wouldn't have thought its the quality of water but I'm no expert on that.
    The low readings could be from not using a salt with elevated levels. You can use a normal salt and add buffers to boost certain elements

    The High TDS reading means you have nutrients in the water, nutrients cause all kinds of issues in Marine Tanks

    ideal for SPS is

    Po4 0.02 and No3 0.25

    of course the numbers don't have to be perfect and many tanks have higher levels than this

    If the water isn't 0 TDS or very close to 0 TDS water changes are not helping your water quality

    I had to learn the hard way, my tank had a Cyano Bacteria Bloom, I was changing 20% of the water each week and it was getting worse not better
    after advise from a forum, I bough a TDS Pen the shop water RO had a TDS OVER 300, MY TAP WATER is only around 60 to 70
    I went to a different LFS and bought RO water, it smelt of Chlorine AKA it was little more than Tap Water
    I bough my own RO unit and my tank improved very quickly

    some LFS do provide good RO water, where are you based ?

    Im based in Bolton. I have been using Cascade water gardens for my water. There is also Dave's aquarium but i wouldn't advise anyone to go there.

    The only other place i could use is Urmston Aquatics which is a few miles from me but has a good rep.

    What kind of job would it be to set up my own RO system?

    You need a cold water pipe and a drain

    The connecter pierces the pipe and feeds the unit to feed the filters

    Some of the shops in South Manchester do RO with 0 TDS
    I don't know the ones North of the city

    Dead easy for your own Ro unit like Clearwater says. Or iv got mine in the garage and run the pipe to the outside tap when I need to use the Ro unit so its not permanent but make sure you have ball valves on all the pipes to keep the Ro membrane wet if doing it this way. And somewhere to mix your salt in to the water I just use an old tank. But there are other containers people use.
