Starting on friday i noticed that about 99% of my corals were closed up and i cannot figure out why. Kinda freaking out.
150g tank about 7 months old. about half of the corals and some of the fish were transfered from our old 60g tank that was set up for about the same amount of time before switching to the 150g
Coral: lots of zoas, 2 Mushroom colonies, 2 hammer heads, 3 fungia, brain, 3 favias, sun coral, cup coral, mini carpet, 2 torches, 4 ricordias (small), gsp, birds nest, bubble coral, elegance coral
and a couple more randoms that i dont know the names.
Fish:
Blue jaw trigger, wrasse, 3 chromis, algea blenny, flame fin tang, snowflake eel, fire shimp, cleamer shrim, 2 turbo snails.
I usually do a 20g water change every friday but am not able to until tuesday because the store is out of salt till then. i noticed that everything but my gsp, and elegance coral is closed up very tightly and my brain and 3 fungias look swollen but still small and the tenticals on the fungia are all shrunken up. dont know what could be going on???
water parameters:
Salinity 1.025
Ph 8.0-8.3
Nitrate 5 (which is quite common in my tank will go down to zero but usually stays between 0-5)
Ammonia 0 (always at 0)
Phosphate .25 (never moves and cant get down to 0)
Calcium 460 (usually fluctuates between 420-440)
Magnesium 1200 (usually always the same)
Alkalinity 9.0 (usually always 8.4)
Nothing has really changed lighting is the same, temperature is stable, nothing had died, and the newest corals were added on oct. 20 but have been doing great. I cant think of anything else to check and really dont want to just "wait it out" and end up having all my corals die.. need help!! thank you!!
