The Marine Color RDC 250 is an excellent choice for a protein skimmer in a saltwater aquarium. It is built with high-quality materials to ensure reliable quality and accuracy, making it a great option for tanks up to 70 gallons in size.

After a few weeks, we’re pleased with the Marine Color RDC 250. The tank skimmer removes waste efficiently and well-built. Once we got it set up, it worked great.

One thing we really like about this skimmer is the high-quality materials that it’s built with. The red and white pipe fittings look great and are very durable, and the acrylic construction ensures that the skimmer will last for a long time. 

The high-efficiency pinwheel pump is also a nice touch, as it ensures that the skimmer collects bubbles smoothly and stably.

There are a few downsides to this skimmer, however. As we mentioned earlier, the instructions that come with it are a bit lacking, so it can be a bit tricky to get it set up properly.

Some users have reported that the pump can be a bit noisy, especially when it’s first starting up. Finally, the skimmer is a bit on the large side, so it may not be the best choice if you have a very small sump.

Pros

• The high-efficiency pinwheel pump ensures that the skimmer collects bubbles smoothly and stably.

We found the Bubble Magus BM-Curve 5 to be an effective protein skimmer. The combination of the needle wheel pump and the bubble plate results in effective skimming, and the unique curved design helps the foam rise unimpeded to the collection cup. 

The skimmer is also easy to clean, with a quick-release collection cup and skimmer body.

One potential downside is that the setup can be a bit tricky, especially for those new to protein skimmers.

5. Aquatic Life KP-30 DC Cone Protein Skimmer

We recently tried out the Aquatic Life KP-30 DC Cone Protein Skimmer in our 240-gallon saltwater aquarium and were impressed with its performance. The skimmer effectively removed organic waste and other pollutants before they could harm our aquarium inhabitants.

We appreciated that the KP-30 model was designed for sump placement and easily fit into our existing sump filter.

The high efficiency DC pump with the upgraded titanium mesh impeller made the protein skimmer an excellent choice for our marine and reef aquariums.

One feature we particularly liked was the air intake muffler, which made for super-quiet operation. The collection cup was also easy to use, with a simple press fit and o-ring for a tight connection.

However, we did find that the large size of the skimmer may not fit in smaller sumps, and the collection cup did need frequent emptying. Additionally, some users reported shipping damage to the collection cup upon arrival.

• High efficiency DC pump

Setting it up was a breeze, and adjusting the foam level to wet or dry was as simple as moving the collection cup up or down. The removable collection cup also made cleaning a breeze.

The compact design of the AquaMaxx HOB-1.5 Hang-On-Back Protein Skimmer is a real space-saver, and the pump placed inside the skimmer itself helps to reduce noise and improve efficiency. The cell-cast acrylic construction is also a nice touch.

We were particularly impressed with the high-quality Italian-made Sicce pumps, and the upgraded AquaMaxx ‘Shark’ pump really boosted the performance of the skimmer. However, we did notice that the skimmer may flood the tank with air bubbles when running, which could be a bit of a nuisance.

The skimmer pump, EVair 400, is efficient and quiet, and the novel pipeless output valve minimizes the risk of flooding.

The skimmer is easy to install and disassembles completely for easy cleaning and maintenance.

The elegant “Beer Bottle” curve of the skimmer body naturally stabilizes the air and water mix as they transition upward within the reaction chamber.

Buying Guide

When it comes to choosing the best protein skimmer for your saltwater aquarium, there are a few key features to consider. Here are some things to keep in mind when making your selection:

Tank Size

The size of your aquarium is an important factor to consider when selecting a protein skimmer. You want to choose a skimmer that is appropriate for the size of your tank. 

If the skimmer is too small, it won’t be able to effectively remove waste from the water.

On the other hand, if the skimmer is too large, it may be too powerful for your tank, which can cause damage to your aquatic life.

Skimmer Type

There are two main types of protein skimmers: hang-on-back (HOB) and in-sump. HOB skimmers are designed to hang on the back of your aquarium, while in-sump skimmers are placed in your sump. 

HOB skimmers are generally easier to install and maintain, while in-sump skimmers tend to be more effective at removing waste.

Skimmer Size

The size of the skimmer is another important factor to consider. You want to choose a skimmer that is appropriately sized for your tank. 

A skimmer that is too small won’t be able to handle the waste your aquatic life produces, while a skimmer that is too large might be too powerful for your tank.

Skimmer Material

Protein skimmers can be made from a variety of materials, including acrylic, PVC, and glass.

Each material has its own advantages and disadvantages. Acrylic is lightweight and durable, but it can scratch easily. 

PVC is affordable and easy to work with, but it may not be as durable as other materials. Glass is strong and durable, but it can be heavy and difficult to work with.

Price

Protein skimmers can range in price from under $50 to over $500. While it may be tempting to choose the cheapest skimmer available, it’s important to remember that you get what you pay for. 

A higher-priced skimmer may be more effective at removing waste and may last longer than a cheaper skimmer.

By considering these factors, you can choose a protein skimmer that is appropriate for your tank and will effectively remove waste from your saltwater aquarium.
