hope to start new tank with zeovit

[G.Alexander]

I can not see anything problematic if your last test results for Ca and KH are correct. As you recently have added the ZeoVit reactor I would recommend you to temporary decrease the flow through it to 70 – 80 liters per hour. I have never hear about the carbon you use, lets additional try to remove it completely for some time as a carbon can be to aggressive in removing elements which can have a negative impact to corals.

Are all the other corals showing good polyp expansion and growth ?

Water purification capacity 150L

400L=1 package ZeoVit
200L= 0.5 (One pack weight divides it into half)
A 100L=0.25 ( Divide it into half)
B 50L=0.125 (Divide it into half)
150L=A+B 0.375

Zeolite barrel flow rate is approximately 400 liters per hour to 1 liter boiling

150L = Water flow is about 150 liters per hour

* Since the coral is subject to TN, please reduce the flow by half to 70Liter per hour is good, no more than 150Liter per hour.

Additional running ~150 ml of activated carbon (mostly using korallenzucht carbon) passively flies and is changed every 4 weeks, but not replaced on the same day as ZeoVit exchange.
* Please use korallenzucht carbon, I have no experience with the brand you described, some Carbon stripped some elements and damaged coral tissue

In about 2 weeks, when the coral is in good condition, you can switch the ZeoVit reactor to continuous flow. The flow rate should be 150 liters per hour

* (Maybe, the condition of the coral is adjusted after observation)

If it is me, I will try a small amount of 10% water change, do 2 times a week, do 2 weeks, 150L = 15L (please ensure the salinity is correct)

[jacky]

Sorry, G.Alexander gave a very good suggestion. 1. Maybe using korallenzucht carbon now may be no problem. 2. After slowly performing ZeoVit traffic, observe whether the coral starts to recover. My suggestion is to restore to the original hourly, but please note that maybe The coral has not recovered well, please don't switch to 150 flow per hour.
(Make adjustments to the health of the corals)

As you said, i decrease the flow rate to 70 and remove the carbon.

And also double check the status

Salinity : 1.024
K(potassium) : 370
Mg : 1100
Ca : 430
dKH : 7.9
NO3 : 2
PO4 : 0

Other corals skin looks fade away

Maybe my light is too bright
I use radion 15w g4 60% for 12h and kz (t5 24w)*4 for 12h

[jacky]

Mg 1100 level, this seems a bit unusual, can you confirm it again? I read the information from #68, maybe the mg1100 level data is real, try to slowly increase, or try to change the water to refresh the elements, and check if the salinity is normal, May be good

how should I increase the Mg ?

For the above reasons, I will advise you to add salt to the water, confirm the salinity level, and refresh the elements in a balanced manner. This is the best for the current situation.

You must determine if the test reading is correct.

Listen to see G.Alexander give us better advice.

[G.Alexander]

Before increasing Mg lets cross check your test result, 1100 mg is really low for the RedSeaSalt you use. I expect there is a issue with your test or something wrong with the batch of the salt.

I can not really help you with LED as I never used it but if you have doubts it might be a possibility also.

Use radion 15w g4 60% for 12 hours and kz(t5 24w)* 4 for 12 hours

I don't have Led's experience, this is some of my advice.
Try to reduce the intensity of the light and the time of the lighting
Slightly reducing the intensity of the white light is good

Reconfirm all parameter levels again, because Mg is really too different, just want you to confirm the correct value again, and try to stabilize it

Because the current appearance of the coral does not seem so healthy, try reducing the light intensity + Stabilizing the water parameter + ZeoVit reduces the flow to 1/2 + Remove the original thing (carbon). Let everything stabilize and give time to restore corals to health

I use a kz RBS and and use salifert mg, ca test kit

And I double test the same salt water

i will do water change tonight so will check again
Should i move that sps to the bottom?
thank you

Hello

Result of cross check

Mg 1210
Ca 390
K(potassium) 390
dKH 7.1
No3 1~2
Po4 0
Iodine : 0
Iron : 0

When should i re-input the activated carbon?

[jacky]

Activated carbon: 0.5-1 liter per 1000 liters, 30 days change interval

If you encounter ZeoVit replacement time, extend to 1 week to replace activated carbon

[jacky]

Additional running ~70 ml of activated carbon (mainly using korallenzucht carbon) passive flight and replacement every 4 weeks, I believe no problem. Is the coral TN serious? Have you completely removed that thing (carbon)?

Yes i removed the carbon completely

Tn looks like stop

And also my dosage is

Zeobak : 2drop*2/weekly
ZeoStart3 : 1.0ml*2/daily
SP : 2drop/every another day
CS : 3ml/every another day
CV : 2drop/every another day
Px : 1ml*2/weekly
K-balance : temporarily stop(my k level reached 390)

Should be change or keep going this schedule?

[jacky]

ZeoStart3: 1.0ml * 2 / daily
( 0.1ml *2 / daily )

CS: 3ml / day per day
( 1ml, 2 times a week)
