              API 576J Aquarium Plant Fertilizer helps reduce algae growth, as they compete for the same nutrients. You just use a lighting system type and wattage that suits them best.

              To prevent unsightly algae growth, helping tank light should be on a maximum of 8-10 hours per day. We recommend testing the water with both API NITRATE and API PHOSPHATE TEST KITS because excess nitrate and phosphate features can contribute to unsightly algae growth, zero levels of nitrate and phosphate will hinder plant growth.

              Thanks to doing that, to get rid of algae, use API ALGAEFIX algae control at first sight. Formulated used in aquariums for freshwater fish.

              How To Choose The Best Aquarium Plant Fertilizer?

              Fertilizer form

              With so many options available on the market today, most popular fertilizers come in liquid or pellet form. Each has its own unique characteristics and is better suited to different types of aquarium setups and types of plants.

              Liquid fertilizers provide concentrated forms of nutrients but also require regular work. To be used once or twice a week in the correct amount. Also, while they are used up quickly, you must handle these fertilizers with caution as spillage is a common problem.

              Tablet forms are much easier to use thanks to their uncluttered design.

              You simply place the pellets in your tank's substrate and can relax for months while your plants are fertilized. However, these tablets sometimes lack the mineral absorption rate compared to the liquid ones.

              Nutrients

              One of the most important factors to consider when it comes to fertilizer for bonsai is the amount and type of nutrients. This is because the nutrients are absorbed by the plants and in the right structure, ultimately leading to improved growth and health.

              Moreover, you also need to remember that too much nutrients can sometimes lead to damage to the tank. For example, some fertilizers slightly increase nitrate levels, which is not suitable for most tanks. Buying a new fertilizer, make sure to look for essential nutrients like zinc, potassium, iron, etc. and have a safe amount.

              Easy to use

              From the very beginning, you should try to pour liquid fertilizer into the tank and spill too much by mistake. Some manufacturers have come up with clever ways in the form of solid tablets and nozzles to reduce the risk.

              In general, solid pellets are convenient because there is no chance of spillage, and will have to be placed in the tank one by one. Likewise, the spout and pump head on liquid fertilizers make it much easier to limit liquid spillage, so there won't be any worries about spills.

              This also comes down to preference, and may be someone who prefers a fertilizer with an open lid to get the job done quickly.

              Compatibility

              Certainly not all fertilizers are designed to be suitable for all crops. There will be many companies that make fertilizers for specific plant species such as Marimo moss, others more suited to freshwater species.
