crushedcoral

Hello everyone, so my 50 gallon frag tank has been cycling for quite a while now and I am ready to add some test coral with this, I want to set up a anemone/mushroom basket, but I have seen other people use my question with this is what would be the best substrate to use in this? Should I go for...

Opinions needed please. In one of my tanks I am currently using crushed corals for the substrate. That tank is not even a year old yet, it is fully cycled though and already has fish and all sorts of inverts thriving. I would like to switch out the crushed coral and replace with sand. Nothing...

Would it be possible to have a sandbed of crushed coral, maybe three to four inches deep? What issues might I encounter? Would I have to vacuum it?

I was looking into crushed coral to put in my second reactor for ph buffering but is the Florida crushed coral same thing as the coraline gravel? Can both be used? Differences?
