The Aquaponics additive bundle includes all the important additives to promote healthy plant growth in an aquaponics system. It also includes test kits to monitor the mineral levels in your water. It will boost vegetable growth in your system and help you to keep your system in balance. This kit can also be use to Fishless Cycle your system, to get the bacteria established and grow plants at the same time.

Potassium, calcium, magnesium and iron are all important additives for your vegetables and water. You will notice leaf deficiencies if their levels are low, and you may experience large swings in pH which causes stress to fish.

To Use as a Fishless Cycle Kit

To cycle a new aquaponics system without fish, aka Fishless Cycling, Seafuel is the first product to use at a rate of 1ml per 10L of water.


How much Seafuel to use for Fishless Cycling?

  • For 1000L or water, 100ml of Seafuel should be used.
  • If there are no plants in the system, this rate of liquid should be added every 2 weeks.
  • With small plants, or seedlings, you should add this much Seafuel per week.
  • With large or well established plants, more Seafuel would equal more growth, however we recommend adding Potassium and Iron too at the rates on their packaging.
