Bob, honestly for any reef tank, I recommend 1 to 1.5 lbs per gallon. So I would like to see you with 200lbs of LR in your tank to have good biological filtration.
Fiji is my favorite, one of your emailed questions. Tonga is nice if you like some branching. And I really encourage getting LR, not base rock. Since it is the main filtration, it should be your primary focus rather than something to skimp upon.
200lbs doesn't look like much, believe it or not. And if you have hobbyists in your area, you can buy it used (those leaving the hobby or downgrading tanks) for about $2 - $3 per pound. If it has a lot of algae, there is a procedure called 'cooking liverock' that will solve that problem and make the rock like new again, without killing the bacteria.
