Thanks for the great video on making your own rock. I’m going to give it a try. Please keep the videos coming.

Can't wait to see how it turns out!

Muito bom! Parabéns!

thanks this is awesome

That was great

Nice technique

Here is a short cut to the curing process that I read about and tried and it actually worked. My version was adding air via air pump and air stone during the curing process shortens it to a few days instead of weeks. Of course if you use the salt method you will still need to get all that salt dissolved.

Thanks for the videos on making live rock. I followed the instructions and made a great15kg piece. However I skipped the bucket part for 8 weeks and placed the rock in the local river for 1 week where the flow rate is 45,360,000 litres per week passing through the rock (quick calculation). The rock salt all devolved and it’s now hollow. Then two weeks in a salt water bath with some live rock. Now it’s looking great in the marine tank and the fish like it. I recommend the river as it speeds up the process by 7 weeks.

Thanks for the video! I’m going to do this on my next build. I’m amazed at the price of synthetic rock. I’d like to make Tonga branches. Perhaps I could use acrylic rod as a skeleton.

Very interesting

Awesome, want to make my own as its expensive to buy, i wondered how the commercial guys make rock and i guess this is the same process.

Awesome video!!!!👍👍👍 Is there a way to attach prices together with an adhesive that would be fish safe for these kind of rocks? Would love any input. Thanks! Great job!!

I've heard that some people even use pasta in their mix to make more cavitys and places for things to live.

hello, nice video compliments, what material did you use?

Nice vid. Have you ever tried using quick dry cement ? You’d have about 20 minutes to work with it once you add water.

I love this project and currently and doing it for my 40 breeder, any building tips?

Hi! Any primer could be used to paint rock? What is specifically pvc primer? Thanks!!

Do you think perlite is a good option to make the rock porous instead of salt? I've heard the salt makes the rock degrade quicker and makes it weaker no idea if this is true

If you don't like the rough dry feeling your hands get from mixing cement bare handed, wash your hands with vinegar afterwards. It will help neutralize the alkalinity of the cement

I wonder if it would be a good idea to toss some bits of angel hair pasta in the mix for added porosity? definitely make things grosser in the curing process.

Hi this looks like fun! Going to make a few small decorations for my aquarium…… um I don’t have a salt water aquarium. Mine is fresh water… rain water to be exact…. Will I leave out the salt? Awesome video. New sub from Australia.

Can you add lime to it to bring the ph up in your tank?

THANK YOU SO MUCH FOR THE TUTORIAL!! would this be safe in a freshwater tank?

Hi! Great video!! I tried it and got some really cool looking pieces! But I'm not sure how to know when exactly it is ready. I've had in in a bucket of freshwater with regular water changes for over a month now. The pH is still higher than my tank pH. Is it safe to add?

One note though. Grey portland cement contains ash, it will leach loads of phosphates into the tank for a few months. So I prefer using white cement.

Can you use normal building sand?

Which pvc primer did you use ?

Hi. Thanks for the video. It's actually very informative. I hav 2 questions: Do you actually need the salt to make the rocks? If yes, it's really needed, is that salt for humam consumption or for pools? I'm trying to get some information to start gathering the products, but since I live in Portugal, Europe I don't have the same products and I might have to try to find what they are used for to look for brands available here.

Thanks for the vid, im going to give this a go! What size grain salts did you use? Everything im finding here in the UK is de-icing rock salt which seems to be the fine grain stuff. Struggling to find the coarse grain salt

Great video! I was wondering if salt is added for chemical reaction or for the salt water fish?

Great video. It's only just dawned on me that I can make rock. I have a question.... Can you use powder calcium carbonate instead of sand, or will that interfere with the chemical reaction?

I dont know what 'portland' cement is - What is the specific reason for this? I'm wondering what I can substitute with in Australia (maybe just general purpose cement?)

What’s the name of the salt that you use please

question, why are you adding a PVC prime into those rocks?, are those for aesthetics only?

What about adding aragonite sand to the mixture ? Will that make it stronger?

What materials you think, could be used to make it lighter

Any issues with the silicate in the sand you used?

Im wanting to do this with my dog's ashes in the mixture. Has anyone tried doing this, how was the mix adjusted.

How do you know when all the salts be dissolved?

Who makes the large grain salt ( what brand / manufacture ) ? Love your video, thanks.

I wonder if I used sand collected from the beach if it would it make the beneficial bacteria integrate into the finished rock. Or, another method - if the finished rock was placed in a sack into the sea among the rocks would that make a quicker bacterial take-up quicker

From my understanding the salt just melts away, so does it matter what kind of salt you use? I can only find salt that you use to de-ice driveways,etc. I can’t seem to find any other type of rock salt

I know I'm a little late... But I have a few questions and hope someone can help me out before I spend 1000s. 1.What happens to the large chunks of rock salt that get trapped inside the concrete and crushed coral mix, does it all dissolve during the freshwater soak process or could trap pieces in the mix spike my salinity one day, should a tang graze to hard and chip away a piece of concrete revealing a chunk of rocksalt? 2. After completely drying from the fresh water soak will I need to put the rocks in RODI water with my salt mix for an additional month or so of curing to remove phosphate from the freshwater, or do I let them dry out and completely solidify first before exposing them to saltwater? 3. Do I need to use both rock salt chucks and fine rocksalt or can I just use big chunks, and if not why would both be ideal? Thanks, any info from anyone who's actually done this would be greatly appreciated.

Hello I'm from Egypt .......... I need the names of the ingredients used to make igneous rocks........ and there is another question, did the idea of ​​rocks work for you without any problems inside the tank????? ...... Does it have an impact on the quality of the sons and marine life?

At what point would you add the coloring agent?

Instead of rock salt what can I us?? Marine salt??or regular salt.m

Can I use calcium carbonate instead of that crushed coral?

Rock is peanut butter 😂😂..lol

Can this be done in fresh water as well?

Can you leave a link to where you bought your rock salt from?

Where do you find those big pieces of salt ?

what is the use of the rock salt ?

Sand, Portland cement and aragonite gravel is the way to go. No shells, no salt. Use gloves to mix touching the cement. Put less water than the video shows. Trust me, I'm doing this since a way a kid for more than 25 years.

How long should you cure in freshwater before everything harmful is leached out? Very good video BTW!

What is the point of the salt please?

Where can i buy rock salt?

Whote about paint
