Making a green water starter is one of the main problems for those guppy hobbyists and planning to start breeding guppies. They didn’t know how to start from scratch to culture their green water. But the question is where the green water came from?
The green water is found in any stagnant water or a swampy area that has no current or flow of water. The high intensity of sunlight gives the transformation of decaying substances into the green water.
The green water starter is coming from any decomposing material on the water such as poop, plants, or even dead animals. One of the samples is cow dung, which is needed to multiply the microplankton and required for a green water starter.
Producing green water is already given, meaning that it is already on our tank. Our fishes provide the green water in our tank. It is not intense yet but it will help to get the intense green water for your live food culture like daphnia.
However, if you didn’t get it. I will explain to you first. You must need to put tap water under the sunlight for long hours up to 1 week with a few fish. The excess feeds and poops will provide green water or else if you do change the water in your tank. It will become decays in your old water and it will slowly evolve into green water. If you are a fishkeeper, you already knew that.
HOW TO MAKE GREEN WATER (Chlorella)
The water container is one of the materials that you needed to start your green water culture for at least 15 to 20 inches deep. The water container help to mix easily your culture daily to avoid the unwanted smell in your culture.
STOCK WATER FOR GREEN WATER STARTER
To generate green water starter, you need aged water for at least 24 hours before use. The water must be dechlorinated and remove the unnecessary chemicals mixed in the water like chlorine and other components.
It is highly suggested to use the water in the aquarium since it has a lot of microorganisms and bacteria that will be converted for the green water.
Rice bran comes from the rice milling process and it has a mixture substance including crude protein, fat, and many more. Besides, you will find the rice brand in any poultry shop near you.
Complete fertilizer has a 14-14-14 ratio of NPK and it contains 14% nitrogen, 14% phosphorus, and 14% potassium. Most of the farmers and gardeners use these fertilizers, especially in the rice fields.
The urea fertilizer contains a ratio of 46-0-0 which has 46% nitrogen, 0% phosphorus, and 0% of potassium. This fertilizer was also available in any garden shop.
STEPS TO CREATE A GREEN WATER STARTER (CHLORELLA)
Prepare the empty container for at least 15 inches to 20 inches of height. Clean the empty container with scrub and dishwashing liquid to remove the dirt or stain on it.
Pour the empty container with stock water. Remember that the stock water was aged for at least 24 hours. In short, any harmful chemicals mixed in the water will be dechlorinated.
Use stock water from the aquarium since it has already had decomposing materials like poop and feeds that may be converted to green water.
If you are done pouring the stock water, start to extract rice bran using an old cloth. Squeeze and extract many times the rice brand in the stock water until you will notice that the rice bran has already been mixed in the stock water.
Add 1 tablespoon of Concentrated Fertilizer (NPK 16-16-16) to the container.
Add 1 tablespoon of Urea Fertilizer (NPK 46-0-0) to the container.
Mix all the ingredients that you put in the container until the rice bran and fertilizers mixed up together.
Keep the culture under direct sunlight. Ideally, It is better to direct it to the sunlight for 4-6 hours to accumulate faster the substance in the mixture.
Remember to stir your green water every morning, noon, and afternoon to avoid the unnecessary smell in the green water mixture.
In this technique, you will have a green water culture/starter that you can use to propagate your chlorella. It is now easy to make green water if you have chlorella (green water with emerald green color).
Magna or moina daphnia loves green water because it has lots of microplankton or phytoplankton in the culture. Therefore, It is suggested to make this method before you get or buy a daphnia starter. Above all, this method is already proven and tested to multiply the daphnia culture.
