Let’s get into the detailed care guide.

Bacopa Salzmannii Watering Requirements

You should use deionized water in your aquarium if you are keeping Bacopa Salzmannii in it. This water is much better to use than tap water as it does not contain any minerals, neither excellent nor harmful.

Reverse osmosis or deionized water is also safe for the fish or other plants in your tank (if you are keeping any). You should also change the water in small proportions. Every week, you should change 30% of water. It will prevent any waste build-up in the tank and keep your other plants and fish healthy.

Substrate Requirements

This aquatic plant needs a substrate to which it can anchor and root. At the base of your aquarium, spread a layer of coarse sand or gravel at the back and plant your Bacopa Salzmannii in it. The height of the substrate should be 2 to 3 inches, and make a slope out of it.

The pH of the substrate should be between 5.5 and 7.5. Avoid using oyster shells, dolomite, crushed coral, or any calcium-carbonate-based substrate. These will change the pH of the soil and make it more alkaline, which is not preferable for this plant.

Light

This appealing plant species thrive in medium light. Even inside water, it needs proper light exposure to carry out photosynthesis and stay alive. The fluorescent lights that are used for aquariums are measured in watts per gallon. Bacopa Salzmannii Purple needs a fluorescent light which is two to four watts per gallon. Its growth rate slows down if it does not receive enough light exposure. You should switch the lights off for 12 hours a day. This way, this plant will be under a circadian rhythm of day and night.

Temperature Tolerance

You should maintain the temperature in the aquarium between 17°C and 30°C. The temperature and warmth also affect the growth rate of this plant. The warmer the temperature, the faster it grows. However, too much heat will kill this beautiful variety.

You should set a separate thermometer in the aquarium to track the temperature. This way, the temperature will never rise or fall unchecked.

Carbon Dioxide

Plants consume carbon dioxide and release oxygen in the day and do the opposite at night. This carbon dioxide supply under the water boosts the growth of Bacopa Salzmannii, and it is why you should set up a system to supply carbon dioxide to your plant.

Carbon dioxide can be supplied to this plant through tablets, yeast generators, or injections. The best method is the injection method.

Fertilizer

Just like other houseplants, aquarium plants also need regular fertilizer to thrive and grow. These plants need nitrogen, phosphorus, potassium, iron, magnesium, and other minerals to keep their foliage fresh and healthy. These minerals also fall on the plant from waste material and fishes’ food, but the amount is not sufficient.

Bacopa Salzmannii should be fertilized weekly with nutrient doses. The easiest way to fertilize this plant is to insert fertilizer tablets into the substrate near the base of the plant.

How to Propagate Bacopa Salzmannii?

Bacopa Salzmannii SP Araguaia is one of the most beautiful and colorful plants that you can plant in your aquarium. This plant acts as an excellent background in aquariums. So if you want to cover most of the backside of your aquarium, you should propagate this plant to produce more of it. Its propagation is as easy as propagating other houseplants. It is propagated through stem cuttings. The best time to take the cuttings is late summer.

This plant produces lateral stems. These stems are separated from the main plant body and planted in a different place; the other care requirements are similar to the mother plant.

Bacopa Salzmannii Basic Features

This plant has a fast growth rate. It quickly reaches its mature height when planted. If its leaves are removed, new growth takes place in less than a month. It is why it is preferred for aquariums.

Dormancy

If your plant is not growing or has dull foliage, it does not mean that the plant has died. Bacopa Salzmannii goes dormant in the dry season or winters. During these days, its growth rate slows down to almost zero. Cease its nutrients supply in those days as it does not need any minerals to grow in dormancy.

Common Problems and Their Solutions

If any pests or diseases attack this plant, you cannot treat them with pesticides or fungicides. It is because these chemicals will also kill the fish. This is why treating problems of aquatic plants need more comprehensive solutions.

Diseases

Black alga is a dangerous disease of this plant. When too much fertilizer is added to an aquarium, the growth of algae increases. The black algae grow over the foliage of the plant and cover its leaves. So if you notice your plant turning black, it is due to increased algal growth. The best way to treat this problem is by changing the water and decreasing its fertilizing schedule.

Pests

The six common pests of Bacopa Salzmannii are detritus worms, planaria, limpets, copepods, hydria, and snails. Some of these pests are eaten by the fish and will be no problem, while others need to be removed. These pests affect the health of the plant and damage the leaves. You can get rid of these pests through the following easy ways:

  1. Keep your aquarium clean.
  2. Decrease fertilization for some time.
  3. Stop adding powdered food.
  4. Manually remove the pests.
  5. Add predators, such as corydoras and loaches.
