a several of my acropora corals are beginning to bleach , some from the top and some from the bottom, and it's the third time it's happening to me and always the same senario : the tank looks great, goos coral growth, water stable and clean, fish having a blast, bring additional few corals, everything is good for a week or two, new corals starts to suffer, old corals also begin to suffer, colonies end up in the trash. i'm really starting to wonder if this hobby is simply
over my head.
i've attached a short video of the the corals for you get a sense of the tank.
parameters:
DKH: 7
cal :450
mag: 1650
no3 :5ppm
po4: 0.04
triton 7 core dosing
cheato refugium
feeding : fish eat twice a day (pellets, frozen, nori..) and the corals i direct feed 2-3 times a week with vitalis sps coral food, as well as dose daily KZ aminos and corals vitalizer.
when everything started i thought that there might be too much light in combination with high ALK, so i reduced the light to very low (almost ambient room light), my ALK was 7 anyhow so didn't do any changes there, and dosed a little phosphate and nitrate to increase nutrients. a week after and nothing seemed to help and things are still going south
as for ICP test, i did send one but by the time i'll get the results probably everything will be gone.thought may be to do 100% water change.
so if anyone has any idea what is going on, then by all means please share.
