I think that's the wrong city?

[ I am currently using the Black Sea Black Barrel
I change 100 gallons a month.]

Usually 5~10% change of water per week. A mixed salt of 400L and black barrel at a time, which may cause a large swing.

If the NP value is correct, then the current situation, the supplement of nutrients is really not necessary.

I don't know if the higher elements have some relationship with the amount of nutrients, and stability is good. With low malnutrition water quality, the elements should also be appropriate.

If it is me, my choice is that the water quality is close to ULNS, and the low Kh and the suitable Ca, K+

Acros coral, low malnutrition water quality, suitable/stable water quality requirements are particularly high

I can't say that I am right. After all, everyone's tastes are different, but this is my cognition.

This is from a paragraph in the guide

Zeovit contains GAC carbon, which runs for 24 days at 24 hours and then exchanges. This can be done passively in the bag or through the reactor. Zeovit does have its own brand and I use it very well. I also used hydro-carbon and Seachem matrices, which worked very well. You really want to pay attention to aggressive carbon such as ROX. For me, ROX is too much for my system and reduces my growth on certain corals.

Typical BRS carbon blocks, I have no experience and can't comment on anything.

Just want to clarify this part

Phosphate 0~0.03 ppm, balanced spectrum, not too much blue light. This also helps the color of the coral

If you are implementing nutrient reduction, the speed should not be too fast, and the water quality parameters should be as stable as possible, otherwise the coral may be subject to additional pressure TN.

Then, you add a lot of nutrients to supplement the nutrients to provide energy to protect the corals.

The excessive accumulation of nutrients also relatively shows the appearance of corals.

In addition, my impression is that phosphate may hinder or delay the calcification of corals.

Coral growth / growth = element consumption

I suddenly remembered an extra idea. Coral is "dumb", I don't know how to describe the meaning of "dumb" in technical terms. It means - high nutrient salt water + low luminosity SPS will inform the zooxanthellae to proliferate to provide SPS nutrients. But this situation will make SPS brown (or become dumb) and almost no SPS growth

That is, the coral tissue is dark and dark brown with smooth tissue and no PE.

As time goes by, corals are in such conditions that they cannot grow more comprehensively, and TN occurs.

Please forgive me for my experience is not very good, I have been thinking about this will be the reason?

Do you think this will be the case?

If you understand what I mean, can you tell me how to call this, thank you.

4 new bulbs just came in on Friday; so I put those in the fixture.
It's an ATI 8-bulb sunpower - should be plenty of PAR. I've used the same fixture for years.

Well, looks like I found the imbalance for the Pink Lemonade...
I don't see it on any other corals. I chopped up that pinkish green milli and I didn't see any on it; not sure why that one's color is off.

When I had AEFW previously, they were clear.
This one is very brown & "easy" to spot. I also didn't notice any bite marks.

Maybe it will be quarantined individually, how do you feel
