Do you have the opportunity to start with a suitable level of salinity to confirm that it is good and stable, maybe the test method is wrong, or buy a new test package cross comparison

I have some additional questions:

How much and how often have you dosed K-Balance ? Do you use K-Balance Strong or the Standard version ?

Which kind of HQI bulbs do you use and how old are they and how old are the T5 bulbs ?

Which kind of test do you use for PO4 ?

Are the corals growing ?

I use refractometer ATC. It's calibrated with Salifert refracto cheсk and I have areometer tropic marine. Water level in my tank is constant because I use ghl sensor auto top off.

Standart version, 4ml/day, automatically.
Power chrome 2*250W (1year old) + 4T5
Hanna ppm and ppb. Now I have 5ppb.
Yes.
Not all, but corals growing.

Looks very good

The HQI bulb is used for one year. It is recommended that you replace it with a new one. It should be old, the spectrum is shifted, not the spectrum required by the coral. Then the T5 lamp is replaced with a new one.

So what is the potassium value? If the value is correct and below 380 mg, the slow increase is good, for example: your method of administration 4ml / day, do x4 times, interval 2hr

4ml / day, do x4 times, interval 2hr, record the current potassium value, such as 340 mg

Increase to 5ml / day, do x4 times, interval 2hr, measure potassium value, for example: 350 mg (level rises),( The time of day increased by 10 mg, which is not too much)

Again, 6ml / day, do x4 times, interval 2hr, measure potassium

And so on

This is safe at a dose of 1 ml, and of course it is possible to fall below or with a balanced or insufficient curve.

Or measure the potassium value by x2, for example, 4ml to 8ml, 8ml / day, do x4 times, interval 2hr

Keep changing water 5~10% per week to improve the growth of corals

I measured Strontium in my aqua with Salifert. That's a new test kit. It showed me 0. I started dosing Brightwell Strontium 1cap/day. Now I can't change my bulbs..

I think that by changing the water every week, it should be enough for the trace element Sr.

Huge element, Kh Ca Mg k+, are they stable?

First find the reason, let the coral grow, the coral growth elements will be consumed, what do you think?

A well-balanced salt mixture that seems to help/stimulate, coral growth, no matter what, 5~10% change by weekly water is good

I don't have any experience in supplementing Sr at present, of course, I believe it should be possible with the test agent.

On the replacement of the light bulb, what kind of trouble you have encountered, maybe I can help with some busy (my experience is not very rich)
