Add zeolite to existing tank

Thank you for the additional information and pictures. Your dosing is on the lower side but as you do not have nutrient issues it is OK.

Looks like corals are loosing tissue starting from the base. This is what I would try:

Reduce your skimmer to skim more dry
Do three water changes each 20% within 10 days

Another thing is the elevated Mg level, it might just be your test kit but my guess is high salinity. I would recommend to cross check salinity with a different accurate instrument to make sure it is not to high.

Hi, Alexander
long time no see.

60 liters of water has been carried out four times and the condition of corals has improved greatly. As coral grows, potassium consumption is increasing. I am seeing coral conditions and dosing iodine and iron. It is about one or two times a week.

AAHC It seems to be algebra when dosing. I do it mainly with bak, start3, sp, zz, bm, pcs, cv.

Two t5s are scheduled to be replaced every month from this week. Thank you for your advice.

Additionaly,
I set the salinity to 33.8ppt, which is 0.5ppt lower than the previous one. Magnesium is 1450.

Hello, Alexander.

The coral is healthy and is getting more and more color. The time to stay in front of the aquarium is getting longer, but there is one problem here. There is too much potassium consumption.

11.28 Potassium 350ppm(salifert)
- Morning k-balance 3ml
- Night   k-balance 3ml
11.29 Potassium 370 ppm(salifert)
- Morning k-balance 3ml
11.30 Potassium 360 ppm(salifert)
- Morning k-balance 3ml

* Alkalinity 132ppm
Salinity 33.4ppt
Temp 25.5 ~ 26.5

Is this normal to be consumed? Although I was lazy to measure potassium, I was embarrassed. What is the reason for the high consumption of potassium in the zeovit system? And, please let me know your experience and how to do it in my case.

I think the needle wheel skimmer might be the problem, you can try to adjust it to skim more dry.

Please also check if the salt mix you use has a adequate level of potassium.

Hi, Alexander,

Thank you for your kind reply.

The problem of low potassium is dosing 3ml of KB daily. Maintain 350~380ppm.
A small amount of potassium chloride will be mixed in the fresh-water to adjust the potassium concentration to 380ppm.

Today I would like to ask about the replacement of T5 lamp.

* AS - IS
ATI T5 Dimmable 39W 8bulb
- Ch1(11 Hours) : Blue+(2)
- Ch2(6 Hours) : Blue+(3), Coral+(2), Purple+(1)

* TO - BE
- Replace two lamps at once
- Ch1(11Hours) : Blue+(2)
- Ch2(6Hours) : True Actnic(3), Blue+(2), Coral+(1)


Questions.
1. Is True Actnic quantity suitable for fluorescence generation?

2. I heard that changing 8 old lamps at once is bad for coral because of sudden light intensity increase. So I want to replace only two lamps at a time. How much time is appropriate between each replacement?

Actinic light does not improve the florescense of the corals really just the human eye does notice a different effect.

If you replace the bulbs all at once you can lift up the fixture temporary to give the corals some more time to adopt.

Hello JUNJONG, do you have a picture of the rocks without the corals?
