Hi Jeff,
The primary motivation was due to skimmer cup size. I travel a lot and wanted to have a larger skimmer cup. I also like their drain line, - something my wife can do while I am away. She could never remove Nyos cup. The large skimmer size was a bonus, my PH is now consistenstly at 8.5 (used to be 8.3-8.4), ORP is high. Must be the larger skimmer body and gas exchange. And, finally, the color match with my plumbing was a nice bonus.
Klir was for the same reason, I am frequenly gone for 2-3 days and hated to see it turn into a food trap with nitrates and phos jumping up and down contingent on me replacing filter pads. I had to dremmel and customize the Reefer 250 sock tray to accomodate, but super happy with Klir now. Each roll lasts me 6 weeks at least and I feed heavily.
Btw, customer of Marine Depot. You guys are great. Keep up the good work.
