Deltec MCE300

The MCE300 is the most compact, quiet and affordable Deltec skimmer to date - suitable for an aquarium between 50 and 75 gallons (225-320 lts).
The high manufacturing tolerances and design of the special venturi and pinwheel produce 130 lts of air per hour giving it the same level of performance that you would expect from all Deltec skimmers and outperforming any other skimmer in its class.

The four most important things to consider for a high performance protein skimmer are:
  • Air Volume
  • Bubble Size
  • Air Volume
  • Air Volume
Foam Fractionation (Protein Skimming) is a process where protein wastes are removed from water by differential electrostatic attraction at an air /water interface. The more air and the smaller the bubbles in contact with the water, the higher the surface area for reaction and the higher the efficiency of the skimmer.

The patented Deltec pinwheel rips the air into the finest bubbles for maximum effect.

Contact time is important but only if there is insufficient air for immediate reaction.

Comparative testing shows that most manufacturers claim a much higher suitable tank size for their skimmers with half the air volume or less.

At Deltec we don`t compromise on water quality

Choose your next skimmer on £ / true performance and you will find that a Deltec skimmer will work out to be the most cost effective of the lot.

deltec mce600 skimmer Product Review by BRIAN EISENMAN (Posted on 2/26/14)

Comments: It may be expensive but is by far the best hang on the back skimmer made. I have had it up and running on my 30 gal. reef for over a week and it is already pulling out waste at an amazing rate. Quiet, no bubbles going back to the tank and extremely efficient. The pump might need to be realigned after shipping but after that the unit is easy to assemble. Yes I would recommend this to anyone who wants the best and this truly is.

Deltec is amazing Product Review by GENE EICKERMAN (Posted on 2/26/14)

Comments: This unit does a GREAT job.It will fill very fast for the first couple of days but then settles down. Runs great and I am very happy with it. I have it on a 90 gallon reef tank that is fairly well stocked. I would buy one again. Great item.

Great Skimmer for HOB Product Review by JASON WILLIAMS (Posted on 2/26/14)

Comments: This is probably the best HOB Skimmer out there, it pulls a decent amount of skim-mate
but still does not compare to a in-sump skimmer.

Love it Product Review by matt (Posted on 7/28/12)

Comments: Tried an AquaC Remora, but it wouldn't fit with my canopy and I didn't like the powerhead in the tank. Next tried a Reef Octopus BH1000. It fit and skimmed well, but it made a constant loud gurgling that drove my wife crazy. Also really hard to assemble and maintain. Decided to try the Deltec, and what a difference! Simple to assemble, really quiet, and started pulling nasty stuff out the first day. It does prime kind of slowly which made me nervous at first, but it's not really a problem.

MCE600 Product Review by ANTHONY HOBSON (Posted on 5/21/12)

Comments: this is the best skimmer i've seen in my young reefing experience. right now the skimmer is making a thick foam that looks like coffee. wow who knew that water had so much nastiness in it. all of my lions and corals seem to be enjoying the new water conditions.

it took about one week to break in and it is a dream the pump isn't that loud as most complain about. the loud thing is the return water hitting the display water. to get around that i tucked a Mag2 filter in between the degassing shield and the mounting bracket so the water falls onto the sponge filter.

the haredest thing is to zero in on the air-valve dial and the height of the box. this skimmer is so strong that it will fill up with water quick if it's not dialed in properly.

overall this skimmer is well worth the money.
