Water top off

+1. I'm not sure what the water in your area is like, but there's a lot more in Calgary's tap water than just chlorine. A LOT more. There are definitely people with beautiful tap water salt water tanks, but it will always be an unknown variable and if you do have problems you'll never be able to say for sure whether or not it's the tap water, or some other problem

I have never used any type of RO water in my reef and have had alot of success, though I do plan on getting an RO system for my next upgrade I don't have any problems.

You technically don't even have to treat your water with prime that's another story. People will give you advice to go do this, or that.

The only thing I find is that I sometimes get excess nutrients causing small amounts of red slime outbreaks but that only happens in the spring run off and the odd time have it has rained a lot.
