• Algae do not grow.

  • Corey3201

The algae just won't grow at all, neither Halimeda nor others, only the glass is slightly green. I wish the stones would get a little covered. Nitrate tests - 0, phosphate - 0. Water volume is 180 liters. There are a Zebrasoma, 3 females, 1 Helmon, 1 clownfish, a boxer shrimp, 2 Trochus snails, 2 Strombus snails, and 2 small hermit crabs.

Besides Carolina, you don't need anything else in the general aquarium. Add calcium, magnesium, and iodine. And if it's necessary, feed the fish more.

I fed once a day with brine shrimp, now I'll try twice, and which calcium is better to use?

There are many opinions here!!!!!! Very good reviews about Tropic ine Bio-calcium. A friend used it and noted a very strong growth of Carolina. But for even more powerful growth, magnesium from Sichema can also be added.

Measured calcium-440.

Rejoice that they are not growing. If they start to grow, you won't know what to do with them.

Just keep in mind that bio-calcium raises the pH along with calcium.

There are no halimeda either, I put 2 stones with halimeda from the previous aquarium and it all disappeared, there is not much left but they have turned black.

This doesn't say anything yet; on the rocks, it could be damaged or even killed. It needs a lot of Ca, and when it lacks easily assimilable calcium, don't expect growth or recovery from the stress. I know that the critical levels for it are calcium ion content (at least 400-450 mg/l) and carbonate complex (alkalinity 3.5-4.0 meq/l, or carbonate hardness 8-12°). The iron ion content should be within 0.05-0.1 mg/l. Well, that's all the minimum.

Maybe Halimeda grew in the previous aquarium because I was doing 10-liter water changes out of 30 three times a week.

I don't know about others, but I really dislike it when the stones in my aquarium start to get covered in algae. I fight it by removing them mechanically. I can't imagine how to deal with them in a large aquarium; do you have to introduce all sorts of algae eaters? So the main thing is that your pets are doing well.

The conversation in this topic is not about the algae that grow on rocks, sand, and the walls of the aquarium; these algae are not beneficial in the aquarium, and not every fish will eat them. They also lack aesthetic appeal and provide no benefits, only trouble for the owner. The algae, that is, macrophytes, are quite beautiful and pleasing to the eye; they are essential in a young aquarium (unless you have set up the aquarium quickly using chemicals, in which case they are not needed, and a different method and approach are required). They are also a very good food source for all surgeonfish. Here are two links for you to read.
