Shrimp Keeping and Filtration Needs
For those of you that are new to the aquarium hobby, setting up proper filtration can seem a bit confusing. Providing a clean and healthy environment for your pet shrimp starts with the water itself.
Shrimp can be more sensitive to water conditions than many tropical fish species, so understanding how aquarium filters can affect those conditions will prove helpful…
pH: is a measurement of how acidic or alkaline the water is. That measurement is expressed as a number on the P/H scale. Most shrimp will prefer pH levels ranging from 6.5 to 9.5, depending upon the species.
kH: is also referred to as temporary hardness, and measures the water’s ability to absorb increased acid without changing the pH level.
gH: is also referred to as general hardness and indicates the temporary hardness levels combined with dissolved ions.
Research on the species of shrimp you plan to keep will provide you with the pH, kH, and gH ranges that can be tolerated. Water chemistry changes are often done with chemical treatments before it reaches the tank, but you need to be aware that some materials used in filter media (discussed below) can alter these levels. Test kits are available that help you to monitor the water chemistry in your tank.
When you set up your new aquarium the water will need to be cycled before you can add your shrimp. Water cycling helps to establish the Nitrogen cycle, a process that converts deadly ammonia into less toxic Nitrites and then safer Nitrates. This process is accomplished through beneficial bacterias that establish homes in your shrimp tank.
While good bacteria will grow over most surfaces in an aquarium, filters often provide ideal homes. Beneficial bacteria are a key component in biological filtration. This short video provides a diagram breakdown of the Nitrogen Cycle.
Water cycling a new tank is accomplished by introducing ammonia into the water column. In the past, this process could take months and some hobbyists would use live fish for their ammonia source. Thankfully, cycling can be accomplished without sacrificing pets by using a piece of food or chemical starters.
Your equipment will provide biological, chemical, and/or mechanical filtration to keep the water column clean. Many shrimp keepers focus on biological and mechanical filtration, but your shrimp or water may require additional chemical filtration from time to time.
Biological Filtration: is accomplished through the Nitrogen cycle discussed previously. Filter media used for biological filtration are designed to provide surfaces where bacteria can establish healthy colonies. Keeping ammonia and nitrite levels low will allow your shrimp to thrive.
Chemical Filtration: uses materials such as activated carbon to leach chemicals from the water column. Introducing materials like peat can influence pH levels as well. Most shrimp keepers adjust water chemistry outside of the tank and use chemical filtration on occasions such as removing excess medicine from the water.
Mechanical Filtration: will use items like filter floss or foams to strain the water column as it passes through the filtering system. This material will clog without regular cleaning. Mechanical filtration is important for shrimp keepers, especially with species that love to dig.
Types of Filters
Some filter designs work better than others in a shrimp tank. Filters types to consider include:
- Sponge Filters – are located in the aquarium and provide good biological and mechanical filtration. Some shrimp keepers prefer them as the sponge prevents fry and smaller shrimp from being sucked into the filter.
- Hanging Filters – or HOB filters are placed on the tank wall and can provide all filtration types. Shrimp will benefit from the extra aeration these models can provide.
- Canister Filters – are external systems that provide all types of filtration. These units handle large volumes of water and may be overkill for a smaller shrimp tank.
- Undergravel Filters – are located under the substrate in a tank. If you plan to use finer substrates that many shrimp species will prefer, this type of filter may struggle below them.
Most filters use an intake to draw the water in. Be careful smaller shrimp, especially fry, can be sucked into the filter. Use a piece of sponge or pantyhose connected with an elastic band to help prevent this. Some intakes are designed to prevent fry from entering the intake.
Shrimp Tank Filter Reviews
XINYOU XY-380 Aquarium Sponge Filter
A simple design that provides that provides safety and filtration.
The foam materials used for the sponge filter are very porous. This design element allows water to move through the thick pad while trapping debris at the surface. While this filter may be too large for a breeder or fry tank, the sponge can provide safe filtering on shrimp tanks that are 10-gallons or more.
The manufacturer offers the filter in one, three, or six-packs.
As a sponge filter, it will provide you with biological and mechanical filtration for the water column. Chemical filtration would need to be provided by another source.
This product will require an air pump to function. Bubbles from the escaping air will help to agitate the surface. That can increase the exchange of gases at the surface, helping to diffuse more oxygen into the water.
- Side channels provide more surface area for bacteria
- Power heads can be attached easily
- Pours are large enough to promote consistent waterflow
- It is bulky and may take up a lot of room in small tanks
- The unit is light and may need to be secured to the tank bottom
Aqua Clear 20 Power Filter
A filter that provides room for mixing multiple filter media.
A flow rate of 100-gallons per hour makes this a good choice for aquariums ranging from 5 to 20-gallons in size. It has a re-filtration design, providing extra contact time with the filter media.
The filter offers the same bottom-up design that canister filters use.
This unit can provide all three filtration types and the filter media compartment is built to accept various materials. AquaClear does offer pre-bagged proprietary filter media, but you can mix and match your own filter media in this product. They also include enough AquaClear Foam, Activated Carbon and BioMax and Cycle Guard to get the filter up and running straight out of the box.
The lid may rattle if it is not placed correctly on top of the housing (but simply make sure it is on correctly to stop this).
Remember to protect your smaller shrimp by placing a piece of sponge or pantyhose across the water intake, and secure it with a rubber band.
- Media storage space allows for mixing filter materials
- Runs quietly when compared to similar units
- This filter is covered by a two-year warranty from the manufacturer
- Debris may become lodged in propeller box
- Cost of proprietary media is quite high
Powkoo Air Pump Sponge Filter for Aquariums
A two sponge design that can be placed almost anywhere.
This product uses two separate sponge heads to provide filtration for aquariums up to 60-gallons. That should cover most tank sizes that shrimp keepers would use. The filter comes with suction cups that allow it to attach along any tank wall, and will keep the unit in place during operation.
If one sponge needs replacing, the second sponge can continue to operate without losing bacteria colonies.
This product will provide both biological and mechanical filtering. The materials the unit is made from are food grade, a feature that prevents them from affecting the water chemistry.
Cleaning will require detaching the filter from the tank wall.
A rotating nozzle allows you to direct water output, and an adjustable vertical tube allows it to fit in a variety of aquariums. The arms holding the sponges can move, allowing the sponges to be placed at angles in roomy tanks.
- Two sponges help to prevent clogging issues
- The extra source of air helps with aeration
- An adjustable nozzle helps direct water flow
- It takes up a lot of room for the sponge size
