I placed back gfo in the reactor because of phosphate issues but removed 1/3 of the usual dose and timed it opposite the zeo reactor. I also did 10% water change with Red Sea salt (5% interval for two days), planning to complete at least 15% in a week. Reactor flow from zeo decreased to 150LPH. I started dosing spongepower, vitalizer, and coral snow (although, I did threw away the rock which has the only cyano spot growing in the tank). Any advise on these ? Vinegar is now totally weaned off. Microbacter 7 will be off in a couple of days. Just fraged and glued corals that are showing stn at the base. Rest of the corals are doing ok
Here are my latest parameters:
Phosphate 0.10
Nitrate 40
Alkalinity 7.5 dKh

You can try to add 4 drops SpongePower daily and 8 ml CoralSnow 2 x weekly if you like to. Until using CV I would recommend to wait until the system runs nutrient poor stabile.

Day #10 with zeovit:
Just a quick update. I am still struggling with my phosphate and nitrate but it's lower than before. Been doing 6gallon water changes with Red Sea salt blue bucket daily making sure to get the detritus out and vacuuming the sand bed. Still has the gfo and carbon in the reactor but only running 2/3 of the recommended dose. Skimmer set to skim wet (cleaning it daily )with air inlet connected to CO2 scrubber and media changed every time it turns purple.

pH. 7.89
PO4 0.06
Nitrate 30
Alk 7.0
Ca 420

Dosing schedule:
Zeobak 4drops per day
Zeo start 0.4 ml twice a day
Zeofood 4 drops per day
Spongepower 4 drops per day
KZflatworm (prophylactic) 4ml/day
CB 4ml twice a week
Bio mate 4 drops every 2 days
Vitalizer 4drops twice a week
Zeo reactor 150LPH

Ended the following:
Vinegar dosing
Microbacter 7
Kalkwasser
Deep sand bed in refugium since started zeovit
Chaeto - since started zeovit

Feeding schedule:
pellets twice a day
1 Frozen cube everyday

Some sps frags red planet, teal turaki, r.vinh, and Hawkin has TN at the base. Rest of the corals are okay. LPS , montis and zoa are unaffected. Fish are happy esp, my blue hippo Tang no ich even with high nitrate.

Thank you.

Day#11
3 coral frag which was encrusting now is in RTN. Don't know the cause.
Alk 7 dKh
PO4 0.10
Nitrate 40
PH 7.84

Cyano seem out of control. Coral snow unable to control despite daily dosing. Will dose chemiclean today (has worked for me before). Carbon off. Aeration increased.

As long you have issues with Cyanos and as long as nutrients are elevated I would recommend to stop the following products, they will just fuel the cyanos additional:

Zeofood, KZflatworm, CB

You can use them later again. The TN might have something to do with the environment changes, you have done a lot of changes in the last weeks. Just can recommend to do changes very slow.

Day #17

PO4 0.06
Nitrate 30
Alk 7 dKh
Cal 420
pH 7.92 (daytime), 7.70 (night)

TN at the base continues, now most of the acro sps has it. My Hawkins, red planet gone. As you can see, my parameter is pretty much unchanged despite water changes, and stopping zeofood and kz flatworm. Even used a different test kit (Red Sea) and results are the same. Polyp extension are gone, but LPS are okay, montis and zoas are fine.
What is causing the these? Because even when I have high nutrient level before my corals are ok. Is there something in the zeovit blue bottles or the stones causing it? Am I overdosing or underdosing any? Do I need to do something else? Or am I missing something?
Before I started zeovit, the system has chronic high nitrate in the range of 40's ppm but my Alk is kept high at 10dKh until I started vinegar dosing wherein I have slowly able to get alk in the 7-7.5 range. Since vinegar dosing my pH was mostly in the low side so I used kalkwasser and ph stayed mostly on average at 8.2 in the morning and 7.85 at night time. I did used chaeto with opposite time to the DT, also to aide in pH issues and help with high nutrient level : nitrates are high- but I was dosing amino acid everyday with Red Sea energy A and B, feeding heavy aside from pellets, I also supplement with oyster feast twice a week, and reef chili twice a week. I did have my GFO and carbon running though 24/7.
I know, before I started zeovit that it will take a lot of patience to get the nutrients down. Now that I switched to zeo, I am more deligent with water changes, not over feeding and skimming wet.
Here is my regimen:

1. Zeobac 4 drops Mon-Wed-Fri (three times a week)
2.Zeostart 0.4ml 2x daily
3. Spongepower 4 drops daily
4. Coral snow 2x a week
5. Biomate 4 drops every 2 days
6. KZ carbon 0.4 liter in passive flow.
7. GFO now only 1/2 of the recommended dose in passive flow
8. Zeo reactor still at 150LPH 3hours off/ 3 hour on interval.

Feeding:
Pellets twice a day
Frozen cube changed to three times a week.

I know it will get better but unless I do something right now, I might not be able to save my acros.

Have you already checked the K+ level of the system ?

There is nothing I can see which is causing the problems except the system changes, can you please additional post some actual coral pictures ?

Hi Alexander,

I did checked my K level before when I started and it was 410. Today I checked my potassium and it reads 420 using salifert test kit. But I did 10% water change last night using Red Sea salt. Please see the pictures of the corals affected by TN. Some corals I already threw away because it's dead. Some I tried to frag ang glue it hoping it will survived.

In the pictures I can see the plating montipora corals are growing so I do expect the K+ level is fine and not the cause of the problem.

All the changes in the last couple of weeks might have stressed the corals, from the point of the dosage I can not see a problem, also the lower reactor flow you still use is absolute correct.

The PH swings are normal and do not cause problem, my recommendation would be stopping to dose the kalkwasser.

Next think I would try are a couple of water changes to refresh elements in a balanced way. Dosing this slowly would be the best so 3 x 10 % within a week might be a good start.

You can additional try to remove 50% of the carbon from some time.

Thanks G.

Kalk has been off for a week now. I will do what you suggest re: water changes.
What do you mean about the carbon? Do you want me to remove 50% of the recommended dose or replace 50% at a time?

Just remove 50% of the carbon you use for some time so in your case just use 0.2 liters.

Thank you G. Do you think the TN could also be caused by high nutrient level since I'm only running half the recommended dose of gfo now and the flow rate from the zeo reactor is only at 150 LPH? I also noticed more green algae growing on the rocks now.

While the algae issues are linked to nutrients I do not expect that this will be the reason for the TN. At the moment do not try to lower the PO4 level to quick, this will just additional stress the corals.
