The Best Filters for Your Shrimp Tank

Choosing the Best Filter for Your Shrimp Tank: A Guide to Different Types of Filters

When it comes to keeping shrimp, a good filtration system is essential for maintaining a healthy and stable environment. There are four types of filters that are commonly used in shrimp tanks, namely sponge filters, undergravel filters (UGF), canister filters, and hang-on-back (HOB) filters. Each of these filters will have their own advantages and disadvantages.

Sponge Filters

Sponge filters are a popular choice for shrimp tanks because they are affordable, efficient, and provide gentle filtration that won’t harm the shrimp. They work by drawing water through a sponge that serves as a mechanical and biological filter. Beneficial bacteria colonise the sponge, they break down organic waste and keep the water clean.

One of the main advantages of sponge filters is their ease of use and maintenance. They are easy to install and clean, and don’t require any special tools or equipment. Additionally, they provide a gentle water flow that won’t harm delicate shrimp or their offspring.

However, sponge filters may not be sufficient for larger tanks or heavily stocked shrimp tanks, as they have a limited filtration capacity. Additionally, they can become clogged easily and require more frequent cleaning compared to other types of filters.

Under gravel Filters (UGF)

Undergravel filter boxes are a popular type of filter for shrimp thanks that use buffering soil. They work by drawing water through a layer of gravel, which serves as both a mechanical and biological filter. The gravel is colonized by beneficial bacteria that break down organic waste and keep the water clean.

The advantage of using UGF with buffering soil comes from the ease of replacing the soil after its buffering capacity has lowered. This provides the least amount of stress for the shrimp in oppose to having to redo their entire tank. Additionally, they provide a gentle water flow that won’t harm the shrimp.

However, undergravel filters may not be suitable for planted shrimp tanks, as the roots of the plants can clog the filter and reduce its efficiency. They may also cause issues with water circulation and oxygenation, especially in larger tanks. Replacing the filter does require some preparations since you will need to pre-cycle the substrate before replacing it.

Hang-on-Back (HOB) Filters

Hang-on-back filters are a versatile type of filter that can be used in shrimp tanks of different sizes. They work by drawing water through a mechanical filter that traps debris and a biological filter that removes harmful chemicals. The filters are typically housed in a plastic cartridge that hangs on the back of the tank.

One advantage of HOB filters is their ease of use and maintenance. They are easy to install and clean, and don’t require any additional equipment or tools. Additionally, they provide a customizable filtration system, as different types of filters can be used in the cartridge.

However, HOB filters may not be suitable for heavily stocked shrimp tanks, as they have a limited filtration capacity. They can also provide a stronger water flow that may harm delicate shrimp. It also isn’t uncommon to have shrimp climb into the filter through the outflow. Also the inflow needs to be protected to prevent shrimp from being sucked into the filter.

Canister Filters

Canister filters are a popular choice for very larger shrimp tanks or heavily stocked shrimp tanks. They work by drawing water through a series of mechanical, biological, and optional chemical filters before returning the water to the tank. The filter, housed in a canister outside of the tank, is less obtrusive than other types of filters.

One advantage of canister filters is their high filtration capacity, making them suitable for larger tanks or heavily stocked shrimp tanks. They also provide a customizable filtration system, as different types of filters can be used to target specific types of waste or contaminants.

However, canister filters can be expensive and require more maintenance compared to other types of filters. They also provide a stronger water flow that may harm delicate shrimp or their offspring if not adjusted properly. Additionally you definitely need to protect the inflow to prevent it from sucking up any shrimp.

Which filter is the right one for you?

In summary, there are several types of filters available for shrimp tanks, each with their own advantages and disadvantages. It’s important to choose a filter that suits the size and stocking level of your tank, while also taking into consideration the needs of your shrimp.

Now that you have chosen the filter for your shrimp you can finish setting up your tank or start cycling your shrimp tank.
