There was a question about white cemant earlier.I use the portland type 3 cement.It cures in half the time as the regular cement.Do any of you use vinagar to soak your rock in right after you make it?I have used pasta to make my rock more pourus.It dissolves in the vinager.I have also used rubber gloves to make my caves.I have a 19 pound chunk in my reef that is totaly hollow in side with holes through the sides.On this piece i used the oyster shells and portland cement.Another material i use is south down sand wich is very cheap to purchase.IMO if you do use the type 3 portland cement then all you need to do is change water every 4 days for about 2 to 3 weeks.Use a large plastic tub and keep it in your garage.
