    I am posting my Water test data for 3 consec months using API reef master test kit and it shows that my water param really unstable.:whistling:
    Inputs:
    3yrs old Tank from FOWLR converted to Reef 1 yr ago
    100g including sump water.
    50g sump with, JEBO520 skimmer, DSB, Phospad, Cheato and refugium
    Additives Calcium plus and reef buffer only

    Tests done 30 mins after every water change

    [​IMG][​IMG]

    i can't make my Phosphate down.
    Nitrate controlled by my cheato
    Calcium raised up by calcium plus but suprised by my KH going down
    Anything i could do in terms of additives?

    TIA...

    Your Cheato, is it growing at a good rate? Or just staying the same size?

    Are you turning it over at least every week? An Algae scrubber and Cheato both should keep the phosphates and nitrates low. What I did find is that it is quicker to bring the nitrates to zero, and the phosphates will take another month or two before they come down. Well that is what happened to me when I put in my scrubber and cheato ball.

    Also, phosphates tend to build up inside the liverock. And you must have very low concentrasion in the water before the phosphates in the rock are released back into the water collumn. What you can try next time you do a water change, keep old water in a bucket and rinse your liverock in it. Just that one time. So you can rinse out some of the locked up phosphates. Just do not keep the rock outside the water, even for 2 minutes. Do not want to kill sponges that is inside the rock.
    Else
    check your phosphates in another month.

    Thank your for undying support RiaanP.

    When i'm keeping a FOWLR tank, i'm doing that rock rinsing in old water. but since i converted the tank to reef. i don 't think i want to disturb the corals and other live things growing in the rock. What i'm doing now is blowing the rock with a little powerhead before siphoning the water..

    With the cheato, Its just two weeks since i got it from a reefermate. the way i see the cheato, it's doing fine with my 20w CFL lighting.. greener as before. turning it upside down once in awhile.

    Skimmer doing its job well but i'm planning to built an algae scrubber soon.

    Sandbed releasing bubbles for quite sometimes. (can't monitor how many in a day)

    i find improvement with my calcium when i made the daily dose..

    Hi there, some points for you to consider :)

    Do not test 30 minutes after a water change, wait at least 3 hours before doing any tests.

    API test kits are not very popular or reliable, I would recommend getting some better test kits, and it looks like this shows in your test results, for your Nitrate to go from 5 up to 40 and then back down to 6, your CA is really jumping around as well, I think you need to buy one or two better make test kits and at least do a comparison. You may be trying to fix a problem that doesn't exist.

    I agree with Viper, double check with other kits first ;)

    Well maybe you're right, i should test my water with other test kits.. However, I used this API reef master test kit on newly mix RO water and teco reef salt and it gave me better result that's the reason i thought this can be reliable and will give me good reading for my tank water as well. But anyway there no harm in trying.. i will update you guys once i tested it with other brand..

    Follow-up: what causes my KH seems going down?

    Daily Regimen:
    I am using R.O water for top-up
    Dosing Calcium plus and reef buffer daily
    TECO ReefSalt Mix (US made) for PWC

    Phyrannus - the most likely causes of alkalinity dropping down, are the following:
    - a drop in pH
    - the natural occurring drop in pH in the evenings in one's tank
    - the natural working of a DSB - where in the lower regions in the an-aerobic/anoxic areas, where the pH of the water also naturally drops, due to the working of the bacteria (generating oxygen and nitrogen gases)....

    Also - forgot to add:
    - dead / rotting plant and animal material also causes a temporary drop in pH (around the area where this is occurring)
