Planted in an afternoon, no algae since
Wei Ling brought the stones I had chosen from photos, built the iwagumi in my living room and talked me through the first month of water changes. Twelve weeks in and the carpet is closed with no algae at all.

Seiryu Stone
Blue-grey limestone with white veins · by the box
The iwagumi stone: blue-grey with fine white veining and deep, sharp creases that read like a mountain range under water. Picked by hand in our yard for the grade you choose and washed before it ships.
A grade is a mix of sizes for building; Select picks pieces with strong texture and flat bases; Main stone is a single feature piece of 4-6 kg. Seiryu raises KH and GH slightly, so we pair it with nature soil to keep the water soft. Price shown is for 5 kg of A grade.

Rated 4.9 out of 54.9 · 403 reviews
Rated 5.0 out of 5 Rated 5.0 out of 5 The PAR figures are honest
Shipped to Japan in four days. I measured the light at the substrate with my own sensor and it was within 5 µmol of their spec sheet, which no other brand I have bought has managed.
Rated 5.0 out of 5 Every shrimp arrived alive
Ordered twenty at 9am, they arrived at 11 in an insulated box with two bags. All alive, eating within an hour of drip acclimation. The care note in the box was written by the person who bred them.
Rated 4.0 out of 5 Beautiful tank, long wait for freight
The 60P is flawless - you genuinely cannot see a green edge. One star off because sea freight to London took five weeks, but they told me that up front and the crate was immaculate.
