4KG Lava Rocks

Perfect for my gas bbq

Ideal for the wood smoker

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.

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

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

this is a very small bag. not enough to cover a four burner barbeque

very Good Product But the bags need to re do the style because of the weight bag are opening for delivery

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.
