Powder or Super powder?

Here are scenario-based recommendations:

• Use the Powder (2-3 mm) version when:

  • You have a more standard planted tank where you’ll use medium-to-large stem plants or background plants and you’re comfortable with standard root spread.

  • You want a substrate that’s a little more forgiving for beginners or general use.

  • You might be doing layout work or placing hardscape (rocks/wood) and want a substrate that is a bit easier to manipulate without so many fine particles.

• Use the Super Powder (1-2 mm) version when:

  • You’re doing a high-tech aquascape with delicate foreground plants (e.g., carpets, fine-leaf stems) or shrimp that benefit from tighter substrate.

  • You’re building a layout with strong slope, detailed hardscape, or want more stability in the substrate layer (finer grains pack more tightly).

  • You’re seeking a slightly cleaner look in the foreground where fine granules may help plants anchor and reduce visual interruption.

You can also use it this way: Use powder as a base and super powder on top to help plants root more easily!

JUN Platinum Soil for Singapore Aquascapes

An active soil like JUN Platinum is doing two jobs at once: feeding plant roots and nudging your water chemistry. That second part is handy in Singapore, where tap water tends to run soft and slightly acidic to begin with, so the soil’s buffering keeps a planted tank or shrimp aquarium sitting comfortably in the mildly acidic range that carpet plants, stems and Caridina prize. Its porous granules also give beneficial bacteria plenty of surface to colonise, helping a young tank settle faster.

For local setups we usually steer high-detail iwagumi and shrimp scapes toward finer grades for a clean front-glass line, while standard planted layouts cope well with the regular powder. Expect some initial ammonia release as the soil activates, which is normal and part of why patient cycling pays off. A light rinse and gentle filling keep clouding down, and topping up with good flow lets the substrate stabilise before livestock goes in.
