Hello reefers, I am relatively new to this hobby and have been using tap water mixed with salt and prime for my tank water. For one reason or another, I have lost a few fish. I know my water here in Fort Collins, CO is considerably clean, but with the issues I have been having, I am now considering switching to either reverse osmosis or distilled water. Can anyone give any insight on whether the switch is worth it for the price and what ya'll use?
