Bob's Rock????

[briangg57]

I was reading the sticky thread about MR spirit and came across a post that said,"What about Bob's rocks, giving the community another cost efficient way to keep PH in good parameters" Could anyone tell me about this??:scratchch:

Bob 1000 makes fake reef rock that has a pretty high PH level. As it sits in your tank it raises PH over time. He makes them in some really cool shapes!
