I have the Coralife Super Skimmers for 65 gal
it really pulls stuff out of the water, Take your time setting it up, the closer the pump is to the the skimmer bowel the higher the water will be in the bowel, I started mine with the skimmer flow in max and it promptly filled the cup with clean sea water. very quickly..
So I backed the flow down and read the manual and it said to leave the water at the lower line for 24 hours to break in the skimmer, and it really started to perk after that I have to empty it daily ( man the junk that comes out is brown and stinks ), I keep it bubbling just below the shoulder of the smaller part of the funnel where the diameter starts to get smaller I belive this causes it to produce a drier concentrated foam, the higher the water the wetter the foam.
I ve also noticed that water in the top third of the skimmer is golden brown so its the first stage of the actual concentation of the stuff before the bubble chamber.
very small bubbles almost a fog. I hear thats the good ones.
I love mine dosen't make a sound sitting on the side of my 20 sand sump.
Oh yea don't add any sand whilst the skimmer is running bad idea. had to clean all the bubble injectors duh. PSPS,,, GFI is a must incase you overflow..total cost at marine depot was plus shippin $88.99 pretty cheap but really good
I find the water level should be equal to the red adjustment device for the water height on mine this works well any higher and it blows a lot of wet foam after a couple hours. my local petstores highly reccomend the corallife skimmers they say the don't seem tobreak down has quicky as some of the other models and is farily easy to clean this restores the skimmer to the same level as when it was new. One nice feature is the bubble trap is inlcuded many systems you have to pay extra for that.
I beleive the smaller unit could easily handle a larger tank maybe up to 100 gal
unless your feeding alot of the fresh meat I check mine alot cause its new. and I am so green ( new tank )
Ok you experts I ve read about trace mineral depleation with skimmer something about iodides being removed after 24 hours ???
