Not sure if this is the right place for my question but,here goes.Can you use RO/DI waste water to cure DIY rock.You know,the process to cure the high pH levels of newly made DIY rock before you can put it in your tank.It seemed like an ok use without just running all that water down the drain.Yea or ney? I would be changing out the water as needed.Are there any problems with the water chemistry I haven't thought of?
