I am near Penticton.
I have set up 65 gal in a 36 inch high tank. 400 watt MH 20K, skimmer, 400 gph wave maker, deep gravel bed cranking 800 gph and an outside nitrate chamber.
Used concrete, coral sand, and ground styrofoam to duplicate a fave dive site. The concrete reef was done in three stacking pieces and cured for 8 weeks in running water.
The ph spike, when I went to salt water, was impressive. I was two weeks and a 50% water change before I got the ph down to 8.3. Seems to be fine now and several small mushrooms have taken residence on the structure. I seeded the tank with 40 lbs of small uncured liverock. I am thinking that estimates of a one month cure time you read about is cutting it a little close and the 4 - 8 months is closer to the safe truth.
