hello
i found this on another site and wondered if in theory this would work. ( i find this after spending loads on rock and sourcing from all over i say sourcing i stole alot of it from various friends tanks )
To make your own rocks, you will need Portland cement and play sand. Portland cement is one of the most commonly use types of cement so it shouldn’t be hard to obtain. It consists chiefly of different calcium silicates, but is usually also filled with clinker phases that can contain iron, aluminum and magnesium. Portland cement is considered safe for aquarium use as long as you get your cement from a reputable producer that adheres to the official cement standards. Portland cement is sold as a powder and will turn into a paste when you mix it with water. As the reaction between cement and water progresses further the paste eventually turns into a solid “rock”. Type 3 Portland cement is recommended, but type 1 or type 2 will also work.
1. Wash the play sand. (This step is not mandatory but will yield stronger rocks.)
2. Mix one part Portland cement with four parts play sand. The result should be pasty and you should be able to form balls in your hand. Always use durable rubber glows to prevent alkali burns!
3. Place damp sand in a container and dig out hole of suitable sizes and shapes – you have now created a mold.
4. Drop the cement mixture into the mold and shape it.
5. If you want to form caves, tunnels, holes etcetera, use more damp sand.
6. Leave to rest for at least 24 hours.
i simply share this with you as a question and take no responsibility for any mishaps if you try this. (see ya in court)
