Barr Aquatic Systems
Barr Beckett Protein Skimmer

Standard Skimmers:

This line of skimmers is custom designed for systems with a capacity of 50-500 gallons. Of course you can run them on a smaller system too, especially if you plan to upgrade your tank in the future.

Easy Maintenance- An amazing all acrylic twist-lock system makes these skimmers unique in the world. Just grab the neck and twist it less than a quarter turn. The special ramps release their water-tight seal and the collection cup can be removed. Needs less than 1/2" clearance to remove. Extremely neat and easy, nothing else can compare. Standard on all skimmers, no $40 extra cost unions here. The Beckett chamber still has key holes and thumb screws to be certain it stays secure during cleaning and general tank maintenance. No removing the pump line just to clean the cup.

The full height injection tube reduces the head pressure that the pump sees for better foam production, and has more than double the contact time than the competition. More contact time equals better performance! Don't settle for a skimmer with 4" of contact distance.

The optional flow meter kit is a great accessory. At a glance you can tell how the skimmer is performing. It will read up to 45 SCFH (Standard Cubic Feet of air per Hour) with a Sequence 3600 pump. If you see the air flow rate change, you know you need to check the pump intake or possibly the Beckett for cleaning. Get instant feedback and precise, repeatable control!

Skimmer ratings depend on your bio load and how the skimmer is plumbed. Please contact us to help you pick a skimmer size that matches your system and growth plans.

Requires a pump that can put out 700+ GPH such as a Sequence 3600, Little Giant 4MDSC, Iwaki 55 or Mag 12 or 18. Best performance is realized at around 800+ GPH, giving an air flow of 45+ SCFH (Standard Cubic Feet of air per Hour).

Breaks down quickly for cleaning. Normally the Beckett does not need to be cleaned, but the collection cup should be cleaned every few weeks for best performance.

See the instructions page on the for setup tips.
