The larger rockes turbo charges our gas firepit
fire pit came with small stones that were OK but limited the flow of gas so flames were just so so. Bought these bigger rocks and now looks amazing as flames can breath and are now twice as high . Wish I had taken a before an after

Other half is VERY happy with these
Purchased for other half’s gas barbecue. Perfect for our needs and gives our BBQs that Smokey BBQ flavour with the convenience of gas. Arrived very quickly and great value for money. Great for our needs. Chunkier than the other BBQ lava rocks we have purchased meaning they don’t slip through the grill.

They do exactly what they should, hold and distribute heat
I’m so glad I found these lava rocks, which were bought to replace old bbq rocks. They have worked extremely well, hold the heat and do exactly what they should

GOOD FILTER MEDIA FOR AQUARIUMS / POND
I used this as a filter media, not a BBQ product so my review reflects that. Very good as a filter media for aquariums or in a shower filter for koi ponds and certainly compares to Bakki house media. Unlike a media like 'Biohome' the structure does not lend itself to anaerobic bacteria support but it is excellent for aerobic bacteria (to convert ammonia to nitrite, nitrite to nitrate) If lots is used and flow rate is reduced then an anaerobic bacteria support is possible so I rate these rocks highly as a DIY filter media and they will last for many years unlike the very expensive ceramic tubes sold by koi outlets which are extremely brittle and wear very quickly. See attached video clip of a DIY shower filter I made for a recent upload on my Youtube channel which showed how to make a shower filter for your pond.

Dieses Tongranulat verleiht dem Blumentopf eine schöne Optik und lässt ihn professioneller und eleganter wirken. Die Kieselsteine sind leicht und haben eine schöne Farbe, wenn sie auf der Erde liegen. Ein Freund hat mir dieses Granulat empfohlen, um kleine Fliegen loszuwerden – ob es in dieser Hinsicht funktioniert, kann ich jedoch noch nicht beurteilen. Insgesamt ein tolles Produkt!

Je les ai mis dans mon BBQ au gaz . C'est une excellente protection pour les brûleur. Fini la fumée des graisses qui brûle! Bonne inertie de la chaleur. C'est tout bon. économie de gaz et assuré et santé préservée!
