    hi all

    Tank Spec - 120cm length, 45cm width, 50cm height
    Running for 4 months
    Running a Zetlight ZP4000 Lancia.

    Tank parameters:
    Ammonia - 0
    Nitrite - 0,05
    Salinity - 1,026
    PH - 8,2
    Nitrate - 2
    Alkalinity - 9
    Calcium - little high at 480

    Lost basically all my sps.
    Green Bali Slimer turned brown and then white.
    3 colour acan is not puffy anymore, more like hard and grey.
    pink milli who has been happy has started bleaching.
    Cyphastrea not vibrant green with red Polyps anymore, more brown green.

    Is the light sufficient from my unit or what else could it be?

    Your phosphates might also be sky high

    Hi guys.
    Still waiting for a po4 test kit and mg test kit.
    Had it tested 2 weeks back, can't remember the values but we're in line.
    You recommend continuous ro water changes to lower calcium or is there another way?

    4 month old tank seems pretty young for an sps tank. You also have nitrite, which should be zero.

    How quick did you stock the tank?

    Only have a few small sps pieces. (Had)
    Only basically zoas and lps now.
    Stocked it after 2months.
    Know it was a bit quick.
    Carry on with water changes regularly?

    Reduce the bioload, allow beneficial bacteria to build up, then add bioload back after a few weeks.

    Or do some research on a product called Special blend i think this will help mature the tank quick. I might very wrong about this product.

    Could be insufficient lighting?

    Biological load. Any life (livestock) that consumes nutrients and excretes waste eg fish, corals, inverts.

    What livestock do you have? And tank size?

    I agree, PO4 might be the silent killer and 4 months is a bit early for SPS and that many livestock
    Your nitrates is fine at 2ppm, you don't want your nitrate and PO4 to be zero. PO4 about 0.04ppm is ok.

    Just caught the last bit now. To confirm that you don't do water changes with RO water, then you drop the salinity and then everything else dies. Do water changes with salt water that you have ether pre-mixed or bought it from the LFS. You top-up the tank with only RO to replace evaporated water and that keeps the salinity in check.

    Don't worry to much about the raised Calcium, water changes will only lower it slightly. It should go down by itself if you have livestock that will consume it.

    I'd suggest double check your salinity with something differant - also any powerheads or such pull them apart & check them for corrosion/rust.
    Bottomed out Po4 will also kill

    All the above parameters is good or even great:m106:calcium at 480 won't kill your coral like the the guys said above it must be something else like phosphates po4 you need to get sample water at a petshop for testing quickly boet and did you test your water before you added livestock?

    Sounds like a combination of a lot of the aforementioned.
    Insufficient lighting
    Fluctuating nutrient levels
    Fluctuating everything i would think
    Although parameters are not all bad, they are a snapshot and don't indicate stability.
    Take a step back,
    Stop spending (wasting) money on live stock, and rather invest it in knowledge, test kits and equipment to ensure you can offer your intended inmates a better chance of survival.
    Then, start with one easier to keep lps and or sps, then once kept these for at least a month (more like two) without any issues, then buy another one of each.
