AquaMaxx EcoMaxx EM200 In-Sump Protein Skimmer Information

Product Manuals & Documentation

AquaMaxx EcoMaxx EM Series In-Sump Protein Skimmers efficiently remove organic waste from aquarium water. A powerful needle wheel pump generates optimally-sized air bubbles that force protein, waste and other materials into a collection cup for easy removal. The AquaMaxx EM Series is rated for aquariums 120-700 gallons yet are small enough to be concealed in a sump underneath your aquarium.

Computer-precision engineered and outfit with the latest filtration technology, AquaMaxx protein skimmers are engineered to deliver the performance and value you are looking for in a skimmer.

AquaMaxx EcoMaxx EM Series Skimmers are built using a brilliantly polished cell-cast acrylic. They incorporate the high-end features hardcore hobbyists demand at a price everyone can afford. The EM Series is equipped with bubble plates, modified cone necks, air silencers and needle wheel impellers for maximum performance, efficiency and whisper quiet operation. They also have compact footprints to make installation as easy as possible.

AquaMaxx EcoMaxx Skimmers feature custom Italian-made Sicce pumps with special needle wheel impellers to whip up large amounts of air with optimum bubble size. These pump and protein skimmer combinations deliver unprecedented performance and reliability. Aquarium waste will be vigorously removed from your tank so you can focus less on maintenance and more on enjoying your piece of the reef.

AquaMaxx EcoMaxx Protein Skimmers are designed from the ground up with the hobbyist in mind. The pump is incorporated into the base of the skimmer for a space-saving design that will be easy to incorporate into your filtration system. A built-in air intake silencer further reduces noise for near-silent operation. The specially-designed transition cone neck effectively moves skimmate into the collection cup for removal. Bubble plates decrease turbulence, improve bubble formation and help skimmer performance.

Comments: I've had this skimmer for only 2weeks and I must say it has performed really well it was skimming nasty stuff in two days! It operates very quiet which was my main concern. It is on my 200dd and has medium bio load. Very well built with a easy to clean body just for screws and it done. So all in all I would recommend this skimmer;-) it's way better than any others I've had over the years! Don't hesitate on this one great skimmer at a great price. Happy Reefing;-)

Comments: I Love this Skimmer. Replaced an older Bermuda venturi skimmer. Setup was very simple. Super quiet--Did I say how quiet it is! Really can't heard it at all. Began producing skimmate within 12 hours. Running about 36 hours right now and working great. Great support from AquaMaxx--I had a prepurchase question and they answered my email in 36 hours. (Height of base is 16 inches, and height of collection cup is 7 inches FYI). Would definitely by again. Would definitely look at other AquaMaxx products as the quality of the skimmer is excellent. 125 gallon mixed reef/30 gallon sump.

Comments: This skimmer is a beast. I love it and would highly recommend this to anyone looking for a skimmer that actually works. It's easy to set up and adjust and it stays adjusted unlike many of the other skimmers I've tried.

Comments: I have just set up the EM 300 on my 150 gallon fish only aquarium and this thing immediately started skimming all sorts of waste out of my tank. Very little break in period, super quiet, extremely well made. Coming from previously using a Reef Octopus on my 55 gallon tank which is also a great skimmer, this thing is just a monster. Great skimmer.

Comments: I love this skimmer. I'm using this on my 460 gallon shark hatching/grow out tank and am extremely impressed with how much skim mate this skimmer pulls from the system. I have to empty the collection cup every two days. Great skimmer for a great price. I will add that this skimmer works best in 8 inches of water.

Comments: This product is excellent. I switched my co1 skimmer for this one and I am not dissappointed. I wanted to test it out on my 125 tank, before i purhase a 220 and it definitely seems strong enough. My corals have not looked so large and healthy! It filters very thoroughly with great intake suction, leaving water debris free. This is the skimmer to choose.

Comments: I bought a EM 200 for my 150 Excellent product. Had it back ordered for months. Very energy economical, I was hoping to get 2 EM 500s for future fish tank 561 gal build. but supply and demand drove the price too high. Wish I ordered before the price hike as they were well worth it then.
