Do all bags of lava rock have Carbon Monoxide warnings and say “Lava rock may contain gas and may explode when heated” 🤔
Anyone using in a reef tank ? Lot's of posts on forums saying not to for some reason they can't remember or they read it somewhere but don't know where. LOL
Hi , i am from sri Lanka and i am watching all your videos . Tks for sharing good ideas . Keep up the good work . 👍 .
Man… I have lava rock in my biological filter and it keeps putting off dirt and soot. No matter how much I clean it. I have to keep changing the water. Anyone else struggle with this water cloudiness when it comes to lava rock.
The only media i use is bio ball that i got for free and bio sponge
Tezontle
and same question for the colorful scrubbies? safe for a reef tank? the colors are safe? no chemicals?
hey King? is the lava rock safe for a reef tank? is there any additives? why am i nervous?. lol
Can we use laterite stone instead of lawa rock??
Plastic bio balls are utter rubbish and over priced.
How about a video showing how to keep some extra oem cycled (cartridge, bio bags, etc) filter media ready-to-go in a small spare aquarium? or why I should NOT do so?
I don't have lava rocks, but I have bricks. Can I crush them up for filter media? Seems porous enough to be effective…
"Lah-vah rock"
awesome, you always have the answers to my questions, thanks a lot!!!
Is it ok if my lava rock red color is fading black
Lava rock is my go to substrate for trickle filters.
And makes a great bulk for under your substrate/ gravel so you need less of expensive substrate like Flourite / Eco-Complete to make those hills and valleys..
Great infomatnal vid Joey
What do u suggest for over head filtration system? Do u think lava rocks will be good enough to be place in the trays? Will lava rock affect the flow of water?
Very informative video . Learned a lot . Thank you
1:42 "Just be careful with that axe" reminded me of the pink Floyd song
can i use micro fibre that cums from a pilow. for bio filter insted of polythene
Old joey
Before everything
After 5 years you still using lava rock? Need to do a video " i still use this"
Starting a 75g right now! Tons of info on the web about filter media and until now wasn't sure what to use. Thanks for the direction. Breakin lava rocks now!!!. Your videos ROCK.
I have to call you robotic Joey you. I feel like I watched you grow over the past 10 years
For polyester filling you DON’T want mildew resistant?
So lava rock would be good for a reef tank
Lucky my backyards filled with lava rock.
Um that axe is gonna get very dull
Great video very informational. Solid Thank you
Wow thanks so much for the info i was just about to set up for the first time a canister filter for a 50 gallon turtle tank and you gave me a lot of great options. Thank you
Saltwater?
Can the lava rock filter keep my tank water clear
The king of DIY you are awesome. I followed many of your videos. I built a DIY cascade filter for my aquarium that works perfect. I was moving some bio-media form a old filter to this new one and notice that my bio filter media was wearing out after 8 months
Can you name a fish for me please??
Hauling my arse to Home Depot to get some lava rock.
ThankYou for the advice
Such a young Joey. Thank you for such great ideas all the time. I love watching the old videos.
