first reef, is tapwater safe in a starter nano?

Calgary spring water run-off isn't fine.

In the years I've been in this hobby, the stores using it have always had problems in the spring. And the tap water users have had their problems as of late as well. All I know is I was going through RO/DI filters like no tomorrow during the early spring.

When you have a lot of money invested, why risk it ?

200ppm x 0.056 = 11.2˚ dKH
200ppm x 0.02 = 4 meq/L

I agree with Danny's range of 8-12 dKH and your's falls within this.

haha woops. I forgot I posted this...

I've been buying RO water for the past few water changes actually. $2 for 5 gallons. use 4 gallons for the change, stock pile 1 gallon for top-off/future use. This little system is real touchy on it's water quality, as I've learned already.

And I'm in the process of upgrading my lighting from 36W of coralife crappylight minis to 150W of PFO HQI, and phosphates/excess nitrates are a no-no.

10 watts per gallon is enough, right?
