This is what I want to use. Not sure if its safe. What you think

I think any kind of cement mix would have lime in it, which would shoot your ph thru the roof.

Marco rock sells some that is safe you buy it from him or he tells the brand and you can get it yourself

This is the low pH cement that can be used for making rock. It is used to line drinking water wells.

Be careful with thats stuff...The properties these construction based products contain are not suitable for an ecosystem such as a reef IMHO...I would stick to a 2 part aquarium based epoxy product and limit the amount used as much as possible...The chemical reaction happening during the curing process can cause undesired reactions throughout the tank and will be attenuated upon the amount used

On a side note: I used a product like that with rock salt for texture on a 50g build with nasty results...it was like a continuous overdosed ALK drip for almost two months and I only did bases for two rocks I wanted standing! I think we used about 12-15lbs of the combined product and salt...just my two cents!
