Potable grade liners for aquaponics

Potable Grade Liners for Home and Commercial-based Aquaponics

At BTL, we’re excited about the growing trend of aquaponics. Aquaponics combines the benefits of aquaculture and hydroponics, and eliminates the drawbacks of each. In the practice of aquaponics, it’s essential to have potable grade liners that are safe for fish, plants and human consumption.

What’s the Difference Between Aquaponics, Aquaculture and Hydroponics?

First, it’s important to know the difference between aquaponics, aquaculture and hydroponics. Though the terms are similar, each process is different.

  • Hydroponics is a process that involves growing plants using mineral nutrient solutions in water without soil. Because hydroponics requires no soil, it allows for growing in climates where it hasn’t traditionally been possible.
  • Aquaculture is the farming of aquatic organisms, such as fish, crustaceans and aquatic plants. Aquaculture produces fish for food, sport and bait, as well as algae and fish eggs. Both marine and freshwater aquaculture processes exist.
  • Aquaponics is the marriage of hydroponics and aquaculture in one integrated system. The fish produce waste, which is an organic food source for the growing plants. The plants naturally filter the water that the fish live in. Microbes and composting worms in the water convert the ammonia from fish waste into food for the plants.

The Importance of Potable Grade Liners in Aquaponics

With the growing popularity of aquaponics and organic gardening, it’s important for farmers to use liners that are environmentally friendly with a potable grade certification. Potable grade liners have been certified and approved to hold drinking water for human consumption. This is the highest rating a liner can receive. Potable grade liners are important for growing the healthiest plants possible, whether you’re a commercial farmer or using aquaponics for your home garden.

All of BTL’s reinforced polyethylene (RPE) and reinforced polypropylene (RPP) liners are potable. RPE and RPP liners are strong, durable and puncture resistant. RPE and RPP liners are perfect for aquaponics, especially compared to PVC liners. PVC liners could potentially leach harmful chemicals, such as plasticizers, into the water. Plasticizers are added to PVC liners to make them more flexible, but are not fish and plant safe.

Benefits of Aquaponics

  • Food production isn’t limited by soil, weather and season
  • Aquaponics can be done indoors
  • Harvest can be done in a few weeks; growing with aquaponics is fast
  • Aquaponics uses 1/10th the water of soil-based gardening and even less than hydroponics or recirculating aquaculture
  • Because water is integral to the process, you can’t over or under water
  • Nutrients used in aquaponics are optimal for plant growth
  • Water is reused and only lost through evaporation and transpiration

    Are there any colors other than black?
    Thanks Geo.

  6. I was interested in two prices. One, 18’x12′ sheet for my aquaponics tank. Two, custom made liner for tank that is 11’2″L x 5″0″W x 2’4″H. Thanks, Eric

  7. Hi. I need a 14’x12′ pond liner for my aquaponics system and 14’x 10′ liner for my grow beds. What will this cost? Thank you.

  8. I am looking for a product to line elevated vegetable beds. Your article on potable grade liners claims “All of BTL’s reinforced polyethylene (RPE) and reinforced polypropylene (RPP) liners are potable.” But nowhere can I find the words RPE or RPP associated with any of your liners, or distinguishing one liner from another.

    Which liners fall into the category of RPE and RPP?

    Which of your liners are NSF-61 certified?

    You only seem to respond by email, so I will look for your answer there.

  9. Lou,
    Thank you for your inquiry.. RPE (reinforced polyethylene) is all of our BTL and PPL products (ex. BTL-12, BTL-24, PPL-24, PPL-45 etc…), RPP (reinforced polypropylene) is the PP-45… Most all of our BTL products have the NSF61 certification. To line your beds you would more likely need the BTL-24 ($0.39 per SF) or BTL-30 ($0.49 per SF). Those would come in a flat sheet of material and would then pleat the corners to fit inside… We also have the option of making a boxed liner with the PP-45 ($2.99 per SF) to just fit in your existing frame. Feel free to give us a call to discuss your project!

  10. Hi looking for food grade Aquaponic grow bed liner but website is extremely hard to navigate. Could you point me in the right direction?

  11. Nikos,
    Most of our liners are NSF 61 certified potable water grade. They are safe for fish, plants and drinking water. There really isn’t a plastic liner that is “food grade”, as there is in packaging material.. Our BTL liners are used for aquaponics and hydroponics all over.. Let me know if you would like a quote!

  12. I have I have many I have many animal water basins that are made out of steel with a corrosion resistant coating that is beginning to rust and I want to cover the insides of the basins with a potable liner rather than replacing all of these water basins they all have float valves to keep the water levels as the animals drink from them so they need to be resilient material that is potable and safe for drinking water can you suggest something for me with material perhaps I can purchase a small test amount to see if it works out first before I place a large order
