Ready to turn your tank into a green oasis? This complete is moneywort good for acquarium care guide will give you all the tools you need for success. Don’t worry—it’s easier than you think!

Ideal Tank Parameters

Moneywort is wonderfully adaptable, but it will truly flourish when you keep it in its sweet spot. Aim for these general conditions:

  • Temperature: 72-82°F (22-28°C) is perfect. It happily lives within the same temperature range as most popular tropical fish like tetras, guppies, and bettas.
  • pH Level: A slightly acidic to neutral pH of 6.0 to 7.5 is ideal. It can tolerate slightly higher, but this is where it grows best.
  • Water Hardness: It prefers soft to moderately hard water (2-15 dGH). If your tap water is extremely hard, it might grow slower, but it will usually adapt.

Lighting Requirements: The Secret to Compact Growth

Light is probably the most important factor in determining how your Moneywort will look. It will survive in low light, but it will thrive in medium to high light.

Under low light, the plant will become “leggy.” This means the space between the sets of leaves will get longer as the plant stretches towards the light source. It will still be green and healthy, just not as dense.

Under medium to high light, you’ll be rewarded with the look everyone wants: tight, bushy, compact growth with vibrant green leaves. A good quality LED light running for 6-8 hours a day is more than enough to achieve this beautiful form.

Substrate and Fertilization Needs

You don’t need a fancy, expensive substrate for Moneywort. Standard aquarium sand or fine gravel works perfectly fine. It’s primarily a water column feeder, meaning it absorbs most of its nutrients directly from the water through its leaves and stem.

However, to really make it pop, consider supplementing with a good all-in-one liquid fertilizer once or twice a week. This ensures it gets all the micronutrients it needs. While not essential, placing a root tab near its base can give it an extra boost, as it will develop a root system to anchor itself.

Do You Need CO2 for Moneywort?

Here’s some great news: you do not need CO2 injection for Moneywort to grow well. This is a major reason it’s so beginner-friendly. It will grow happily in a “low-tech” tank without any extra equipment.

That said, if you do have a high-tech setup with CO2, Moneywort will go into overdrive. Its growth will become incredibly fast, dense, and lush. Think of CO2 as an optional turbo-charger, not a requirement.

How to Plant and Propagate Moneywort Like a Pro

Learning how to is moneywort good for acquarium planting is simple. When you buy Moneywort, it will likely come in a bunch held together by a lead weight or foam. Remove this immediately.

  1. Separate the bunch into individual stems. Don’t plant it as one big clump—this restricts water flow and can cause the inner stems to rot.
  2. Using your fingers or a pair of aquascaping tweezers, plant each stem into the substrate, about 1-2 inches deep.
  3. Space the stems about an inch apart. This gives them room to grow and fill in, creating a beautiful forest effect.

Propagation is even easier! Once a stem gets tall, simply snip the top 3-4 inches off with scissors. Remove the lowest pair of leaves from the cutting and plant it right back into the substrate. That’s it! The original stem will sprout new side shoots, and the cutting will grow into a new plant. You can turn one bunch into a full background in just a few months.

Regular trimming and replanting the tops will also encourage bushier growth from the base.

Yellowing Leaves (Nutrient Deficiencies)
