Well, I had been running my almost 6 month reef on city tap water. Just bit the bullet and bought a BRS 75 GPD RO/DI Plus system...
After the crazy weather we have been having I realize that its just not cool not knowing what is getting dumped into my tank.
One of my zoas and my sea fan seem to be acting different since the weather has started. It maybe the tuns of salt going into the water from the street salting or some chemicals being used to combat something I dont know about.
Now that I purchased it... I cant wait to have it... I think I will be doing 5 gallon water changes until I have changed the total amount of water....
