MC500/1 Internal Protein Skimmer

The Deltec MC500 and MC501 Internal Protein Skimmers are the ideal solution when you want to keep everything inside the aquarium or as a compact sump protein skimmer.

The MC500 is fitted with a full size pinwheel and generates 350-400 lts of air at the pump like the TS1250.

Suitable for aquariums from 450-650 lts  (100-140 UK G) stocking.

Now also available as a DC controllable version, the MC501.


When starting up in marine fish keeping many people opt for a budget low efficiency protein skimmer which gets thrown away after 6 months or when they upgrade the size of their systems.

You should therefore bear in mind that this protien skimmer will not only be suitable for the 50 gallon aquarium that you are looking at now but can be reused in their subsequent systems for anything up to 120 gallons. This makes much more financial sense than spending up to 2 thirds of the Deltec price or more on the budget skimmer and then throwing it away when you move up to your next tank.



Tank mounted Installation

The MC500 fits tidily inside the aquarium against either the back or side wall and normally can be fitted using the bracket supplied, (either clear front face or black back face forwards). As long as the water level does not exceed the maximum shown on the body then the unit will operate.

The MC500 protein skimmer will not fit easily on the new Vision 450 and for this tank we recommend the MCE600 protein skimmer with the return flowing into the corner filter box.


Sump Mounted Installation

The protein skimmer can be used in any sump as long as the water depth is greater than 125mm and does not exceed the max level shown on the body. An adjustable weir plate is provided which raises the water level to the correct height for any depth of water.
