• Help a theorist to understand.

Good day to everyone! Here’s the situation! Fate brought me together with "the sea" today. I usually deal with freshwater, but here it is. A lady wanted to create a marine aquarium with 360 liters. They did it for her. They sent live rocks, filled it up, and connected an FX-6 with the live rocks. There are very few rocks. Two pumps and a column. The aquarium is two months old. There are about five amphiprions, a pair of argus fish, and a long blue fish that cleans everything (I don’t know what it is). There are soft corals and little anemones. The entire coral is covered with some brown algae. Could this be diatom algae, the kind we encounter in freshwater due to excess calcium and magnesium in the water? It appeared two months after the setup. Can coral theoretically increase water hardness? If we dilute it with distilled water?

Here is the theory: the term Coralite is not entirely clear; if it refers to the substrate, then the brown algae could be diatoms, dinoflagellates, or cyanobacteria.

And make saltwater into freshwater! Is this an external filter? I mean, there is no sump!? Read the theory and at least roughly explain the situation happening in the aquarium in marine language. It's hard to understand what's wrong with you! Although FX-6 is already not that! What is this?

Do you have a penny or is this the column? What kind of light is it?

What is in the canister? It would be good to check for ammonia, nitrite, KH, pH, nitrate/phosphate as well. Identify the living creatures, fish - for diseases - post photos, maybe someone can help. Replace the light with marine and adjust the light cycle.

The light on these lamps is 9000K blue spectrum, which is not critical for soft corals and fish. Determine what kind of film it is, diatoms or cyanobacteria; diatoms grow everywhere, on glass and decorations, while cyanobacteria usually grow on sand. Is the sand definitely for a marine aquarium? It should consist of 99.9% calcium carbonate (CaCO3). A canister filter is not the best helper in a marine setup, regardless of what it is filled with, as it can poison all living things at any moment.

water.

Sorry, guys, I didn't understand the situation.

Everything is fine. Start dancing from the stove: water, salt, stones, light.

These dances will blow my mind, but I'm really enjoying it. Thank you all!))))

Yes, M.A. (marine aquarium) is absolutely a different level!!!
