Sort of new to saltwater

Hello,
I was pointed here to find fish and corals for a few tanks I maintain for others.  I have been doing FW for 20 years on and off, but I never have actually kept my own tank, I kind of fell into the maintenance business when I bought a 92 corner bow full setup for $200 and found out that he had a 125 reef in his office that was in pretty bad shape.  It was basically a FOWLR, Nitrates around 200ppm, phosphates way up, etc.  After a few months of research, I decided to take the plunge'.  It took a major sump cleaning and re-working, and about 2 months worth of PWCs and that finally got the Nitrates down to 0 and they've stayed there for months now.
I picked up another 125 FOWLR in a chinese restaurant that had basically not had a PWC done in years, Nitrates over 500 and cyano running rampant.  Same deal, massive cleaning & PWCs, Nitrates still a problem (40-80) but the cyano is gone, added 50lbs of LR to what he had, added large CUC, cut lighting and feeding.  Still working on that one.
Then I took over a 200 with same as above, no PWC for 3 years, 800 ppm Nitrate, 20 ppm Phosphate, temp 65, only thing that survived was a 4" Yellow Tang and a clown which eventually died.  Cyano rampant in this one also.  I took the smart route and took the fish out, emptied the tank and threw away the substrate, sanded scratches off the inside acrylic (THAT was fun), and re-piped everything.  As for the LR, I took it out, scrubbed it, soaked in my tub, then sprayed with straight bleach followed by hot water, then Prime, then soaked for about a week to be safe.  It's been up and running for about 3 weeks now (saved the bio-balls by putting in QT with the Tang),
All 3 of these customers have been itching for new fish.  Hopefully I will find some at the swap today!

 

I do keep journals on Aquarium Advice...as long as this site doesn't block outside links, here they are
