Comments: I've been running a Red Sea Max 250 for almost three years now and have never been happy with the skimmer it came with but couldn't bring myself to upgrade. I finally bought this skimmer a few weeks ago and now I'm wishing I'd bought it much sooner. Compared to the old skimmer this one is dead silent. It was a little noisy the first week or so while it was breaking in and I was making fine adjustments, but now that it's pretty well adjusted and broken in I really have to listen hard to hear it at all. There are also no micro bubbles in my display anymore which was one of many problems with the old skimmer. The construction of the skimmer is high quality with nice finishing on the small details (beveled edges, filed down edges of screw holes, etc.). The only problem I had was that one of the screws stripped out when I was putting it on my tank (that was probably my fault for over tightening it though). Other than that I haven't had any problems and it's been pulling much more and much darker skimmate than my old skimmer. I gave it 4.5 stars instead of 5 because the collection cup is a little small in my opinion, and only the front of the cup is clear which makes it hard to see if/when I need to empty it. If it were clear on the top I would be able to look at it from the access flap on the RSM hood instead of lifting the entire hood up. Overall this is a great skimmer and I highly recommend it to anyone with a Red Sea Max or anyone looking for a good skimmer for a tank around 50-75 gallons.

Comments: Bought this skimmer for my Red Sea max 250 due to constant bubbles from stock rsm skimmer and noise issue. Deltec skimmer is great but you need to be patient at first cause my first impression was kind of disappointment cause while skimmer braiking in it was too loud ,I could not control a foam it was some issue with micro bubbles as well all these for almost $500 product ? I was at the verge of return it but now I glad I stick with this product after about week or so and after adding a life stock to my aquarium this thing is working perfectly no noise no bubbles, nasty stuff in a collection bucket plus very easy adjustment as long as I keep my water level constant and some how it became so quite I can't believe So this a great product just a little costly and required some patienece at first

Comments: Easy to use, easy to set, pulls out some really gross stinky thick sludge.My first skimmer didn't work(seaclown), second skimmer(coralife) worked good but would for no reason start over skimming and flood the floor, Third skimmer(current usa 8105) was just way too big and didnt pull out any more than the coralife, This one is small enough to fit inside my sump, and besides having to empty it every day, works great.I am running this on a heavy stocked 110.

Comments: Got this for my RSM 250. Couldn't be happier with it's performance. Easy to fit, easy to run, easy to clean. Increase in water clarity, decrease in green algae on the glass and quiet! Never any microbubbles in the tank, not even from the start. My tank is pretty heavily stocked and this skimmer handles it with ease...highly recommend!

Comments: Just got this skimmer to replace the one that came with my elos mini, which was impossible to adjust. It fits perfectly and was truly plug and play. Haven't gotten it fully broken in yet but this skimmer is amazing!!! Was pulling dark gunk out of the water within two hours. I've used several skimmers over the years and I've seen nothing like this before. Definitely recommend!
