just thinking aloud, but is the Omega line up getting replaced with something newer soon? just been wondering since they've been on sale for what seems for ever now to almost try and push the old products off the shelves. Nothing wrong with that, just wondering as I like the 180I, but I like buying the newest versions always lol...bad expensive habit!
I have the 180i on my new 750xxl and I rarely get any skimate. I feed 2-3x a day with a purple tang, blue hippo tang, 2 chromis, 2 clownfish, bta, royal gramma, yellow watchman, 1 peppermint shrimp, 5 turbo, 3 astrea. I also feed zooplankton for my sps every other day. Maybe I need more fish? Po4@ 0 and nitrate @ 5 on salifert and api. I may have to downgrade skimmer. Tank has been running about 1 month (transfered everything from a 1yr 55g reef) with skimmer in vinegar for a week before I added to tank. Just a caution to anyone who's planning on a 180i in a 750xxl.
I love the quality but so far not its working for me yet. I'll give it another month and if its still not working I'm going to downgrade. I just think it's too big for my tank. I've tried everything from YouTube to hours of reading forums on trying to tune the vertex. A+ quality though.
