I think it is appropriate to re-explain to our passionate friends what this methodology of running our beloved pools consists of.
Do not be scared, it is nothing transcendental, indeed it is very simple. I think it is well known that there are few rules to follow for the success of a tank:
1) Have a balanced triad (about Ca 400/420, kh 7-8, mg 1350-1380);
2) Keep the nutrients under control (for Sps tanks) in a range between 0.01 and 0.03;
3) Make water changes, to the extent of 10% every 15-20 days, with a well-balanced sale to rebalance all those substances assimilated by the tank system.
Starting from this base, few other rules are to be followed, because it has obtained the stability of this value, no tank presents problems. To maintain stability, a good technique is also required, neither under nor oversized, in order to allow any type of decompensation, both in excess and in defect. What do we mean by technique?
The lighting (led, combined with a few T5, for those who want to breed Sps corals, T5 for Lps).
Depending on the chosen light sources, even the t5 are fine for the Sps, you need to combine a correct skimmer. I think it is well known that the LEDs have a greater oxidizing power than the T5 and therefore the combination of the skimmer of our tank is strictly related to the luminous parameter. Never combine a led ceiling light with a powerful skimmer because you run the risk of thinning the tank too much, leading to the progressive deterioration of our beloved Sps, which very few substances would find in the tank to be synthesized necessary for growth and brilliance.
Movement is also very important, because our closed system must allow correct water circulation, in the meantime to facilitate the gaseous exchange, which allows not only the elimination of excess CO2 with facilitating stabilization in increasing pH, but also to ensure that no residues accumulate on the bottom, a source of increased nitrates and phosphates, the primary cause of darkening and blocking the growth of our corals. Finding the square isn't always easy, but with the tank observation method, you find the right balance in everything.
If we were to run into problems of pollutant peaks, for example, we could act indifferently on the light sources or on the skimmer, or through a combination of the two technical data. We could, as we said, begin to lower our ceiling lights by about ten centimeters with respect to the surface of the water, to allow greater penetration of the luminous coefficient, thus increasing the redox, providing, at the same time, to foam more wet, in so as to eliminate more quickly than oxidized. On the contrary, we could foam drier, reducing the photoperiod by one hour, allowing the skimmer to be more aggressive towards the pollutants present in the water. All very calmly, combined with the observation of the reactions in the tank, helping us to use the tests. This type of changes must be observed within a month, because a drastic reduction in leaning of the tank could blow up the bench.
But believe me it is not difficult.
If, on the other hand, to speed up certain procedures we start playing with "bottles" (miraculous products according to those who produce them) we will only make things worse. Pumping the tank of bacteria, just to give an example, will lead to bacterial proliferation, which will have the logical consequence of the relative explosion, with the result of turbid and milky water with corals that spin and doomed to certain death.
NATURE HAS ITS TIMES THAT MUST BE RESPECTED, OTHERWISE IT BACKGROUNDS.
Many complain of an explosion of cyano bacteria and, without even resorting to tests, use the chemiclean, which causes imbalances to the entire system and which, unfortunately, we will realize it too late ... natural way, perhaps with an extra water change, or by increasing the circulation of water in the infested areas and you will see that the problem will be solved. The same can be said for filamentous algae, we check the value of the silicates present in the water, see if our osmosis system works at full capacity and we will solve this problem too. If we have problems with the VALONIA seaweed, let's get some mitraxes or a vlamingi nose and they will be eliminated. The same for planarians, we measure the value of iron, let's get the kelinodura varians nudibranch or banana fish (Halichoeres Chrisus) for their elimination without resorting to chemistry.
There is no specific product to feed corals, but in any tank, Sps or Lps that it was, we insert fish branches, in proportion to the litter, and what is eliminated from them as waste, will be sufficient to feed our corals.
These are the few rules to follow with the natural method, no secrets, saving money not spent on useless bottles and excellent results.
Everything else is boring...
Good reef at all
