Seaweed cultivation requires good dripping quality, and coral sand, coarse sand, gravel sand, dolomite and other materials are all good substrates. There is a big gap between these sand materials, which is beneficial to the root growth of aquatic plants and can purify water without muddy water.

Never use substrate in the choice of substrate, because the gap between substrates is too small and the oxygen supply is insufficient, which is not conducive to root growth and is easy to cause root rot; At the same time, it is easy to muddy the water and affect the photosynthesis of algae.

In the process of algae cultivation, some special nutrient solutions beneficial to fish and aquatic plants should be supplemented in time to promote the growth of algae and a good ecological balance in the tank.

Extended data:

Algae originated from terrestrial angiosperms. Most of them evolved from the same angiosperms 70 million years ago, and re-entered the ocean several million years ago and formed their own unique living habits.

This makes them obviously different from other plant groups that have migrated to the marine ecosystem, such as salt marsh plants, mangroves and algae, and their population abundance has never exceeded 100 species at any time in the evolution process.

Seaweed is beautiful in shape, colorful and graceful. It is planted in an aquarium and decorated with river sand, sunken wood, etc., which looks beautiful and generous. It is one of the best decorations and ornamental items in the aquarium.
