Diy lr

I got myself a SCA cube and wanted the rock to look a certain way.

2 part # 2 potland cement (low alcalinity from HD)
3 parts corse crushed coral
2 part fine crushed coral
1 part argonite sand

Add little water at the time and mixed together until it feels like the perfect oat meal consistency.

Then add 2 parts corse water softener salt mix and put in mold


Plexi glass support structure that got coated in the aggregate. I used templates to make flat spots on the shelf rock and made holes so 1/2” PVC pipe can fit in and connect the two top pieces to the shelf rock. I used the same templates for the top rocks so they fir perfectly onto the shelve rock.

Yes, but you have to cure it for about a month until the PH doesn’t go up in the water you cure it in.
I have it in a tub and do daily water changes. I also add a bit of muriatic acid to start with a lower ph after water changes.

Ok, good to know. Thanks.
The sand in the tub is what kind?

Just regular sand from HD. It’s 4 bucks a bag and I used 2 bags for the mold. Make sure it is moist when you make the mold. Let the rock cure for 24h and then handle with care until fully cured.
