At AquaCave, we offer some of the best selection & best prices on ASM Protein Skimmers for you marine, reef, and freshwater aquarium.

ASM protein skimmers deliver when other skimmers fail. ASM harnesses a patented technique of needle wheel technology. Built from top to bottom with high quality scratch resistant extruded PVC tubing and the injection molded plastic acrylic provides you with not only a skimmer that will perform day in and day out, but can withstand the wear and tear of every day use in the reef aquarium. They are made at a lower cost, which will not affect the performance or quality, yet pass the savings on to you. These hand-made protein skimmers are easy to install, simply place inside your sump, plug it in, and adjust the out pipe flow rate. The out pipe on these skimmers is fully adjustable, it is merely a brisk up and down motion to raise and lower the height of the outlet pipe to dial in flow rate precisely with ease and accuracy.

ASM’s come complete with a Sedra pump or G series pump which is modified to create and produce some of the highest amount of bubbles per square inch of water, on the market today. They perform best, when placed directly in your sump.

ASM skimmers are offered in many different sizes to meet your aquarium needs. Sizes may vary, depending on your bio load and reef size. ASM skimmers will bring your Biotope to life, as your nutrient levels begin to come within proper ranges for optimal health and coloration of your tank mates. Ask one of our Technicians for advice on choosing an ASM for your aquarium.
