Deltec SC 1456 Internal Skimmer

Review – Deltec SC 1456 Internal Skimmer

I have always subscribed to the KISS theory (keep it simple stupid) when tending to my reef tanks so I love it when I come across a piece of equipment that makes my life easier. A number of months ago I purchased an internal Deltec SC 1456 skimmer and it has literally been a set it and forget piece of equipment. Once I adjusted the foam level to the desired level, I sat back and watched it collect A LOT of sludge-like skimmate. No constant tinkering or fine-tuning.

And what about maintenance? Well, there is not a lot to worry about. The skimmer is very easy to disassemble and clean, including the incredibly quiet, low wattage DC pump. Once a month I pull the air line out of the bottom of the pump’s muffler and let it suck in some tank water to clean out any deposits in the Venturi. Additionally, every three months I remove the pump and clean it to make sure the inside is completely free of gunk and any calcium deposits.

The skimmer has a very small footprint and is incredibly efficient for its size.

Deltec SC 1456 Internal Skimmer Specifications

  • Dimensions (LxWxH) / 9.2 x 5.5 x 20.6 inches
  • Dimensions plus pipework 10.2 x 6 x 20.6 inches
  • Power consumption – 16-17 watts
  • Airflow – 600 litre/hr

It is important to make sure you properly size the skimmer with your system so it is a really good idea to consult with the manufacturer or a Deltec retailer.  I ended up going with this skimmer since my prior skimmer was actually too big for my bio load.  So bigger is not necessarily better when it comes to skimmers.


Overall, I would highly recommend the economical Deltec SC 1456 to any reef keeper looking for a high performing skimmer that is both reliable and hassle-free, a characteristic I truly appreciate!
