Determining the Correct Dosage

When preparing to add GLA fertilizers to your plants, it’s crucial to determine the correct dosage based on several factors. These include the type of plant, its growth stage, and the specific GLA fertilizer being used. Taking these factors into account will help ensure that you’re not over or under-fertilizing, which can have negative effects on your plants.

To determine the correct dosage, start by checking the label or instructions provided by the manufacturer of the GLA fertilizer. This will often give you a recommended dosage based on the size of your growing container. However, it’s important to remember that this is just a starting point.

Next, consider the growth stage of your plants. Different stages of growth require different levels of nutrients, so you may need to adjust your dosage accordingly. For example, seedlings and young plants require less fertilizer than mature plants in the flowering stage.

Finally, consider the specific needs of your plants. Some plants are heavy feeders and require more nutrients than others. Additionally, some GLA fertilizers may contain other nutrients that your plants may not need as much of, so it may be necessary to adjust the dosage accordingly.

By taking these factors into account, you can determine the correct dosage of GLA fertilizer for your plants, ensuring that they receive the nutrients they need for healthy growth and development.

Choosing the Right GLA Fert Product

How Often to Add GLA Ferts

Maintaining GLA fert levels is key to ensuring the health and growth of your aquatic plants. The frequency at which you need to add GLA fertilizers can vary depending on several factors such as the type of plants you have, the size of your aquarium, and the level of lighting and CO2 injection. As a general rule, it is recommended to do a 50% water change once a week and add fresh fertilizer at that time.

However, you should also monitor your plants closely and adjust the feeding schedule accordingly. If your plants are showing signs of stunted growth or discoloration, you may need to increase the frequency of fertilization. On the other hand, if you notice excessive algae growth, it may be a sign that you are overfeeding your plants and may need to decrease the frequency of fertilization.

Regular testing of water parameters and observation of plant growth are essential in determining the right feeding schedule for your aquarium.


Adding GLA ferts to your aquarium can be an overwhelming task, but with a few simple steps, anyone can become a pro. Remember to test your water parameters and start with small doses, gradually increasing as needed.
