Worth knowing before you build with it: seiryu contains calcium carbonate. Calcium carbonate slowly dissolves, which raises GH (general hardness, the calcium and magnesium content), KH (carbonate hardness, the buffer against pH swings) and pH. In a tank kept deliberately soft that works against you; in already hard water it makes little practical difference.\u003c\/p\u003e\n\u003ch2\u003eKey Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSharp, layered texture with pale veining for mountain-style layouts\u003c\/li\u003e\n\u003cli\u003eDense and heavy, so it stays put once placed\u003c\/li\u003e\n\u003cli\u003eProvides some buffering against pH crashes in soft water\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eUsage \u0026amp; Instructions\u003c\/h2\u003e\n\u003cp\u003eScrub and rinse before use. Plan the layout dry, then place stones directly on the tank base or on a thin cushion so weight is spread. Test GH, KH and pH before adding the stone and again over the following weeks so you know how much it has moved the water, and factor that into water-change water.\u003c\/p\u003e\n\u003ch2\u003eRisk \u0026amp; Awareness\u003c\/h2\u003e\n\u003cp\u003eSeiryu raises hardness and pH over time; check readings and be aware that active soils and tannins can be pushing the other way.

It is essentially inert, meaning it does not dissolve into the water, so unlike seiryu stone it does not push hardness or pH around. The craggy surface gives mosses and small epiphyte plants somewhere to grip, and the pockets shelter small shrimp.\u003c\/p\u003e\n\u003ch2\u003eKey Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eInert, so it leaves GH, KH and pH where they were\u003c\/li\u003e\n\u003cli\u003ePitted texture that moss and epiphytes attach to readily\u003c\/li\u003e\n\u003cli\u003eBrittle enough to break to size with a hammer and chisel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eUsage \u0026amp; Instructions\u003c\/h2\u003e\n\u003cp\u003eRinse and scrub well: the holes hold fine clay dust that clouds water.

The porosity is the useful part: its sponge-like structure holds an enormous internal surface, which gives the beneficial bacteria that turn ammonia into less harmful compounds somewhere to live, so it works as biological filter media as well as hardscape. It is generally inert and does not alter hardness or pH.
