If your corals are healthy and doing fine you can try to switch the reactor to continuous flow about one week after the first ZeoVit exchange. This should be helpful to reduce PO4 slowly over the time.

Also vacuum the sand while each water change for some time to remove the sediments from the deeper sand layers. Adjust your skimmer to skim more wet and clean it daily or every other day to export as much as possible. While doing this keep a eye on the K+ level.

Ok got it. Continuous flow through reactor 1 week after 1st media change.
I ll check potassium level today and keep you posted.
I will also do a 10% waterchange.
Should i try any other product for lowering phosphate?

I think, you just need to be careful not to lower the PO4 speed too fast, which will put pressure on the coral.

I am with Jacky, no additional products are necessary at this stage. Lets see if the level slowly starts to decrease within the next weeks.

Sure will not add anythng to bring down phosphates lets wait and see if it comes down automatically.
Brought alk down to 7 dkh. I think i ll bring it up to 7.5 dkh.
Calcium is high 450
Potassium was low as u said 350ppm. Will slowly increase it to 400 within a weeks time. I use diy solution of potassium chloride for it.
Thanks
Some pics of my reef again

Can you put a picture of the coral "Pale" in the light of natural balance?

Hello Reefer, congratulations, the coral looks healthy.

If the coral tissue becomes lighter, has good PE and grows, I believe it is no problem.

This also means that your water quality is good (low nutrient salt), which is usually accompanied by green, light green, not dark green

If you are worried, you can check if it is appropriate
1. Lighting time
2.SG
3. Zeolite flow rate
4. How to use activated carbon
5. Pest problems
6. Suitable temperature
7. Individuals are unhealthy
8. The position of the coral is placed and the water flow is too strong.
9.K+ level
A little thought, if not, I hope you don’t see it.


If most of the coral tissue is light and PE grows, you can start feeding through a low malnutrition environment, for example: Zeo CV, AA

congratulations, The coral is beautiful and healthy.

From the two pictures I can not see anything negative about this coral, I would say the green coloration it had before is not the “natural” coloration of it. If it does still show good growth and polyp expansion I would not worry much about it at the moment.

Most likely the lighter coloration of that Montipora is due to going from a "high" nutrient level system to a "NSW / ULN" system. Once it settles, and gets used to the "current" nutrient levels it should get a little more full in the colors, especially if you start dosing some more feeding-supplements as Jacky suggested!

Btw, have your potassium gone up to the recommended range yet? Potassium deficit can make corals lighter as well.
