How to Grow Ceratopteris Thalictroides Water Sprite?

It’s easy to grow water sprite as they are hardy and have invasive abilities. However, it is necessary to adopt a proper method to observe lush green growth. Here are some steps that will help you to achieve it.

Preparation of Tank

Optimize all water parameters and other aspects, i.e., lighting, filtration, etc. Here are the optimal growth parameters for the water sprite.

Parameter Value
Water Temperature 68–82°F
pH 6.0–7.5
Water hardness 2–15 dKH
CO2 Not required
Lighting 2 to 3 watts per gallon with full spectrum light
Lighting exposure 10 hours per day
Flow Rate No, or Low flow rate

Once you are done with the parameter optimization, it’s time to plantation.

Selection of Growth Methods

There are three methods that you can adapt to grow your water sprite. It includes

Free-floating Growing in substrate Attached with hardscape

All three are equally easy, but it depends on your choice. However, go with substrate and grow on hardscape to control its invasive nature.

Plantation

If you want erect and bushy growth, grow them in the substrate. You can use gravel, sand, or aquarium soil as substrate. Burry the cutting of water sprite up to 2 to 3 inches in the substrate. Make sure the crown remains out of the substrate. Maintain a 2 to 3 inches distance between the two plants.

Because they grow at a high rate, their branches can tangle with each other.

You can anchor it on the rock, driftwood, or other hardscapes. Use a fish line and tie the plant to the hardscape. Ensure that the roots always have access to water. Floating triggers the fastest growth rate as they have direct access to CO2.

Ceratopteris Thalictroides Water Sprite Plant Care

It requires low maintenance but requires. With proper care and maintenance, you can observe optimal growth rates and easily control their invasive nature. Here is the daily care guide for your water sprite.

Light Check

Adjust the timer of your full spectrum LED between 8 and 10 hours per day. If you feel yellowness in your plant, increase light intensity. Check whether all lights are functional or not. If you find a defective one, then replace it.

Check Water Quality

Check the water temperature, pH level, and hardiness. If you find any parameters out of the optimal range, immediately fix it. However, never make drastic changes as they can stress out the plants and fish.

Plant Inspection

Check the plant and plant leaves. If you find yellowing, browning, or decaying leaves, immediately remove them. If you find the branches out of their range, trim them to bring them back to their original shape.

Nutrient Application

If the plant does not show lush green even after adjusting the lights, check the nutrient level. Use liquid fertilizers to ensure the proper nutrient distribution.

Water Flow Rate

Check the tank’s water flow rate. If it’s too strong, adjust it to medium or low. If lowering the flow rate is impossible, relocate the plant to a dead zone. This will also help you control nutrient accumulation.
