In general, if anyone is interested, it seems that the limit is around 3 ppm.

Just measured the water supply 0.5 ppm, in the aquarium 0.0. It should be less than 0.03.

The display should have zero silicates as well as phosphates! Some may say that the typical value of silicon dioxide for the ocean is 0.06 - 2.7 ppm, and many marine organisms feed on or have shells, but our reef is not the open ocean, please do not forget that. For a deeper understanding, read more, but remember that the aquarium is not the world ocean. What are you talking about? At a silicate level of 3 ppm, your marine aquarium, specifically the live rocks, will be overrun with filamentous algae, and the sand will be covered with diatoms and all sorts of muck, and then you will spend at least six months getting rid of it all.

Allow me to disagree. There are no silicates 0.1 -diatoms. Sponges grow like crazy. Angels, of course, eat them wherever they can find them, but nevertheless, I believe that a normal system should aim for the world ocean. With its own regulatory mechanisms.

You don't have to agree with me; it's your right to maintain your system as you see fit. There are successful results, and then there are mediocre aquariums. Comparing an aquarium with phosphates to one without them, the difference will be immediately noticeable. I have one aquarium with 1.5 phosphates, and I don't care about them, but many find it uncomfortable. Most soft corals are thriving and blooming, but there are corals that cannot tolerate phosphates; some live in stress, while others simply decline. However, that doesn't mean it has to be this way; it's not the right approach. It's a slow decline of the reef if the situation is not corrected.
