Itshe lentaba-mlilo(eyaziwa nangokuthi i-basalt enezimbobo noma itshe le-lava) iyidwala lemvelo elinobungani nemvelo elakhiwe yi-lava yentaba-mlilo ephola ngokushesha ngamabhamuza egesi avalelekile. Yakhiwe ikakhulukazi yi-i-silica (SiO₂, 50%–60%), i-alumina, i-iron oxide, i-calcium, i-magnesium, kanye ne-trace elements ecebile njenge-sodium, i-potassium, ne-titanium, inezici ezihlukileisakhiwo sezinyosi esinezimbobo (izimbobo 20%–40%), indawo ephezulu, ukumuncwa okunamandla, ukungangeni kwamakhemikhali, ukumelana nokuguguleka, kanye nokuvikela ukushisa. Ayisebenzi ngemisebe futhi iphephile, isetshenziswa kabanzi ekuhlanzweni kwamanzi, ekuvikelweni kwemvelo, ekwakheni, ekubukeni kwezwe, kanye nasezolimo.

Okuluhlazaitshe lentaba-mliloicutshungulwa ngokuchoboza, ukuhluza, ukuwasha, nokomisa ukuze kususwe ukungcola. Amazinga asezingeni eliphezulu anayousayizi wembobo efanayo (0.1–2mm), amandla aphezulu okusebenza (≥15MPa), kanye ne-pH ezinzile (6.5–8.5), okuqinisekisa ukuqina nokusebenza okuqhubekayo ekuhlungeni nasekwakheni.

Ubuso bayo obunezimbobo nobumahhadla bulungele ukuhluzwa kwezinto eziphilayo:

• ◆ Amanzi Angcolile Kamasipala Nezimboni: Njenge-bio-filter media ezihlungini ezivuvukele umoya, isusa i-COD, i-ammonia nitrogen, kanye nezinsimbi ezisindayo; yandisa impilo yesevisi uma kuqhathaniswa ne-activated carbon.
• ◆ Amanzi Okuphuza Nama-aquarium: Ithatha indawo yesihlabathi se-quartz/i-activated carbon ukuze imunce ukungcola, i-chlorine, futhi ihlakulele amabhaktheriya ane-nitrogen ukuze athole amanzi acwebile.
• ◆ Ukwelashwa Okujulile Kwamanzi Emvula Nendle: Kunciphisa ukungcola ukuze kuhlangatshezwane nezindinganiso zokusebenzisa kabusha.

Ukuhlanganisaisisindo esincane, ukuvimbela ukushisa, ukumuncwa komsindo, kanye nokumelana nokushelela:

• ◆ Izindonga Zangaphandle Nangaphakathi: Ukuthungwa kwemvelo, okumelana nomlilo, okumelana nesimo sezulu; ilungele ama-villa, amahhotela, nezindawo zamasiko.
• ◆ Ukwakheka Kwezwe Nokugandaya Imigwaqo: Ayisheleli, ihlala isikhathi eside ezindaweni zokungena, ama-patio, kanye nama-rockeries engadini.
• ◆ Ukufakwa Kokushisa Okulula: Ukushisa okuphansi kokushisa kokuvikela uphahla kanye nama-lining angashisi.
• ◆ Isiko Elingenanhlabathi Nokuguqulwa Kwenhlabathi: Isakhiwo esinezimbobo sithuthukisa ukungena komoya/ukuphuma kwamanzi; sikhipha izakhi ezincane ukuze kukhuthazwe ukukhula kwezimpande (ama-succulents, ama-orchid).
• ◆ Izendlalelo Zokulala Nezokudla Kwezilwane: Imunca umswakama/iphunga; inezela amaminerali emfuyo/izinkukhu.
