Crawtec equipment for modern aquarium keeping
Aquarium keeping in Ukraine is actively developing, and more and more people want to see in their homes and commercial properties not just an aquarium, but a real living ecosystem with crystal clear water and healthy fish. However, most aquarium systems today are still based on filtration technologies from a century ago: foam rubber, synthetic padding, washcloths, "stockings". These approaches are outdated and do not meet modern requirements.
The Crawtec company is well known as the leader of Ukraine in the field of industrial closed water supply systems (RAS). And here it is important to understand: an aquarium is also a recirculation system, that is, in fact, a micro-RAS. That is why Crawtec equipment becomes an ideal solution for any scale of aquarium keeping - from small decorative systems to huge exhibition aquariums for hundreds of thousands of liters.
Crawtec has all the technical capabilities to quickly and efficiently manufacture equipment even for the largest aquariums in Ukraine - with a volume of 100,000 liters, 200,000 liters and more. This is a level unattainable for most manufacturers.
Crawtec automatic drum filters — instead of foam rubber and synthetic padding
Today, filtration in aquarium keeping must be modern and technologically advanced. Crawtec offers automatic drum filters — a solution that is fundamentally different from classic approaches.
This is not primitive foam rubber that has to be constantly washed and wrung out. This is a smart system that itself:
- determines the moment when dirt has accumulated;
- starts washing without human intervention;
- goes back into standby mode, consuming a minimum of electricity.
- The filter element is a stainless steel micro sieve with a cell size of 40, 50 or 60 microns. This level of purification is unattainable for old approaches and provides maximum energy efficiency.
New generation biofiltration
Another problem with classic aquarium keeping is the use of bio-loading based on ceramics, expanded clay or other materials that quickly lose their effectiveness. Over time, they become covered with biofilm, accumulate dirt, and have to be removed, washed, and sometimes even calcined or replaced with a new one.
In 2025, this looks like complete nonsense.
Crawtec uses bioloading that is self-cleaning and maintains stable efficiency, does not require replacement even after many years of operation. These are materials tested in industrial RAS, where the stocking density reaches hundreds of kilograms of fish per 1 m³ of water, and feeding occurs with high-protein feed. If Crawtec biofiltration copes with such loads, then for aquariums it becomes a perfect and reliable solution.
Water sterilization - fish health and system transparency
Another important aspect of aquaristics is water sterilization. Crawtec uses the same technologies that are used in industrial RAS. Compared to the high biological load in fish farming, aquariums have significantly lower requirements. That is why the use of Crawtec solutions guarantees source transparency of water and the health of your fish.
Crawtec Aquariums — Modernity in Everything
Crawtec is not limited to just filter manufacturing. The company is capable of creating turnkey aquariums from the most modern materials. For example, for those who want to get a truly unique product, it is possible to manufacture aquariums from polypropylene. This solution distinguishes the customer, makes their aquarium modern, durable and easy to maintain.
Why is Crawtec the best choice for aquarium keeping?
1. Experience in industrial RAS. If the equipment works on farms with hundreds of tons of fish, it will also cope flawlessly in aquariums.
2. Modern technologies. Automatic drum filters, new generation bio-loading, effective sterilization.
3. Individual solutions. Crawtec can manufacture equipment for any aquarium — from decorative systems to giant exhibition aquariums.
4. Design possibilities. Aquariums made of polypropylene are a new word in modern aquarium keeping.
Aquarium keeping of the future is impossible without modern equipment. And today in Ukraine there is a company that sets the standards of quality and technology - Crawtec.
If you want your aquarium to look perfect and its inhabitants to be healthy, choose solutions from Crawtec - leaders in the world of RAS and aquarium technologies.
The Future of Aquarium Keeping with Crawtec: From Home Solutions to the Largest Aquariums
Today, an aquarium is no longer just a decorative element in a home or office. It is a full-fledged ecosystem that requires careful maintenance and high technology. Crawtec proves that the quality and reliability of industrial RAS solutions can be scaled for any task - from small aquariums with a volume of 200-300 liters to giant public aquariums with a volume of 100,000-200,000 liters.
Automation as a Key to Aquarist Comfort
Traditional aquarium systems require constant participation: washing sponges, rinsing ceramics, removing plaque from glass. Crawtec offers a fundamentally different approach:
- intelligent filters determine the moment of rinsing themselves;
- monitoring systems allow you to control water parameters online;
- energy-saving pumps provide round-the-clock circulation without overspending electricity.
Thanks to this, the aquarium can enjoy the beauty of the underwater world more, rather than waste time on routine.
A new generation aquarium: polypropylene instead of glass.
Another breakthrough offered by Crawtec is the production of aquariums from polypropylene. This material has long been used in industrial RAS due to its strength, hygiene and durability. For aquariums, it opens up new possibilities:
- no risk of cracks and leaks;
- lightweight design compared to glass;
- ability to create non-standard shapes and sizes;
- easy surface maintenance.
A polypropylene aquarium looks modern, is reliable and becomes a real accent in any interior.
Crawtec for restaurants, zoos and public aquariums
Ukraine has examples of large aquarium installations in shopping centers, business centers, restaurants. Such objects require solutions of a different scale, and this is where Crawtec shows its advantage. The company is capable of quickly producing equipment for systems with a capacity of 50,000–200,000 liters and more.
Automatic drum filters easily handle water flows of hundreds of cubic meters per hour.
Industrial bio-loading guarantees stable operation even at a fish stocking density unachievable for conventional aquarium filters.
UV water sterilization ensures ideal water transparency, which is especially important for spectators.
Energy efficiency and economy
The modern world requires not only quality, but also economical use of resources. Crawtec offers solutions that reduce energy and water costs:
automatic filters consume energy only during backwashing;
correctly selected pumps ensure optimal circulation at minimal cost;
modern bio-filters operate for years without replacing the load.
As a result, the aquarium owner receives a system that is not only effective, but also economical in the long term.
Crawtec and global trends in aquarium keeping
Large designer aquariums in hotels, offices, and private homes have long been gaining popularity around the world. This is not only aesthetics, but also a way to emphasize the status and technological advancement of the space. Crawtec implements the same technologies that are used in leading aquarium complexes in Europe and Asia, making them available in Ukraine.
The company offers not only equipment, but also a full range of services:
- design of an aquarium system;
- turnkey equipment manufacturing;
- delivery;
- installation and launch.
A look into the future
Aquarium keeping is developing rapidly. In the coming years, the emphasis will be on:
- full automation of processes;
- maximum energy efficiency;
- individual design solutions;
- use of environmentally friendly and durable materials.
And in all these areas, Crawtec is already setting standards today. Therefore, for those who want an aquarium of the future now, the choice is obvious - Crawtec.
