Fungia and problems.

[Kurtzisa]

Hello, I have two fungia (i don't know how to write the plural form of "fungia") in my tank and I can see his skeleton.
I have a 400 lt DSB tank and I have recently passed a lot of trouble with high po4 0,5 and low ph 7,6-7,7, a lot of SPS dies in the last two months. But the most of LPS (achanthastrea, euphilia and other) are ok.
Now I have no3 5 and po4 0,1, kh 7, ca 400 mg 1400.
I have an Ultrareef UKS-180 I think I don't have any organic dissolved in my tank because the glass (of the tank) is clear even after a week.
So I turn off my skimmer to increase the organic in my tank, i'm starting to feeding my lps with fish Hikari pellets or using integra power sps of "linea unica" but the tissue doesn't grow.

any suggestion?

Bump...

I target feed my euphyllia with mysis shrimp and the start healthy and growing.

I tried with mysis and copepods... I try to insit on feeding for a while

what is salinity as well and what are you using to test all of these things? how are you dosing to deal with daily uptake? what salt mix are you using? this is more for the sps corals but them dying isnt a good sign either.

also tds of rodi water, just based on a fungia doing bad (they are usually very hardy) i would do a 20-30% water change with 0 tds rodi water and check the newly mixed saltwater to make sure i dont have a bad batch of salt mix. and add a bag of activated carbon just in case

Sign of stress from water chemistry change. Usually alk. Ph. Or salinity. Hths.

U can move the coral.closer to the rock for lower flow and light and see if it improves.

true pH that low could be an issue, can you run a co2 scubber or airline to outside, or even just open windows in the room? it might help with ph

salinity 35%0, the refractometer is calibrated with Ati standard solution at 35%0, I'm used to calibrating it with rodi water but this is one of the biggest mistakes.
I'm using tropic marine pro reef, I have a 20 kg bucket, 4 months old. but i can check the value.
Rodi water is 0 +-1 tds
i've already installed a co2 scrubber, but i don't see any difference. (Is spring in Italy so i open the windows every day and night too)
I'm using a calcium reactor to maintain ca, kh and mg

for like 4 months (the problem started in mid-December) my water chemistry was really bad, salinity at 28%0 because I'm used to calibrating the refractometer with rodi, po4 at 0.5 for a bad batch of activated carbon, because of that 90% of my sps start to die, my dog gave birth without milk so I have to feed the puppy by myself every 3 hours and I haven't enough time for the tank.
by the way, at the end of January the salinity was right, the po4 start to decrease with rowa resins, at the end of march the fungia start to have a problem but the remaining sps start to growht and the other lps are healthy. My friend gave me some nearly-to-die zooanthus and after a week they are in better shape but they are in my refugium.

I can try to move the fungias in my refugium but probably is another stress?

 

[dedragon]

sorry that this is all happening at once, that wouldnt really help the fungia at all though. Have you checked pH in the calcium reactor or recalibrated the pH probe?

 

[Kurtzisa]

Both ph probe recalibrated, ph 8.2 and calcium reactor 7.3

This evening, "spaghetti allo scoglio" for me and sqid for my corals, every lps eat a small piece of it
