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?
