CONCEPT
This is an Ultimate Soil.
ADVANCED SOIL is 100% natural substrate that was developed for anyone who wishes to grow aquatic life easily.
ADVANCED SOIL quickly lowers water pH and KH, creating a natural environment in an aquarium. This allows you to have fish in an aquarium on the very day you set up an aquarium with ADVANCED SOIL.
* Basically, it is recommended to put the fish in a week later after you set up an aquarium and maintain water circulation.
ADVANCED SOIL is suitable for freshwater fish such as Red Bee shrimps, Neon Tetras, Cardinal Tetras, Angelfish, and those which prefer mildly acidic water conditions. ADVANCED SOIL absorbs harmful substances in water and thus keeps water clear, saving you time from frequent water changes. Just keep the right number of fish and follow the instructions, then you will keep your fish in good condition for a long term.

Black Color soil
The color of Advanced soil is “Black” because it uses natural andosol, which is a rare and high-quality ingredient from nature. It will impress you with an extremely cool and smart contrast between black soil and aquatic plants and fish in the aquarium. ADVANCED SOIL already contains the necessary nutrients and absorbs excess substances in the water. Therefore, it makes crystal clear water and helps maintain good water conditions.

Maintains a slightly acidic pH over long periods, helps prevent algae growth,
and significantly improves water clarity.
A large amount of organic acids are contained in ADVANCED SOIL. This is the key secret to lowering water pH more effectively than other substrates. Selected black soil is exclusively used for ADVANCED SOIL. Organic acids are gradually released into water from soil and maintain the best conditions of pH and KH for a long term. During the manufacturing process, excess nitrogen (N) and phosphorus (P) are eliminated. On the other hand, it has adsorption ability, it means algae does not grow as easily compared with other products.
*Please avoid direct sunlight. ADVANCED SOIL has granules that are denser than other conventional products. This prevents each granule from flying all over so that the water quickly settles.
Comparison of ADVANCED SOIL with other products
ADVANCED SOIL can adjust the water quality to a mildly acidic level and maintain it for a long term. Typically, soil products lose the effect after 2 months to half a year and can no longer lower the pH level. However, ADVANCED SOIL can keep the effect for over a year with regular maintenance.
