This a LAfishguy video about a huge reef tank which is home to over 100 rose bubble tipped anemones. Heres the thing, they exclusively use LA city tap water in this tank! Enjoy!
I agree that it may not be what most people would do for a tank, however it seems that most people do what works for them. I find this hobby to be full of different ideas on how to do things, but it is what the person with the system thinks works for them. We can offer our ways of doing things, but really that is all we can do.
