I trust many of you are getting ready for the growing season. Some have shelved the ebook and didn't build anything as of yet. It's never too late to start. Also, I know some are in different seasons due to being in Australia or other countries south of the equator.
This blog post is just a review here for many. I want to discuss two vital elements of the aquaponics system: grow bed media and water. The grow bed medium is the plant environment, while the water is the fish. It's a must that we maintain both properly. If there are issues in one, it will manifest in the other.
With any grow media, you want to make sure that it is chemically inert and can't affect the water's pH. I have a video on testing grow media with vinegar to ensure it's pH neutral. Testing with vinegar is a common practice, especially with gravel. The reason is that limestone can be present; this will drive the water's pH up, hindering the system. The majority of the time, gravel, lava rock, and many river stones are pH neutral.
Your water should be pure and clean. Don't use water from a river, pond, etc. It should not have chlorine or any other chemicals. Suppose it is from a local municipality and it does have chlorine. In that case, you need to dechlorinate it by using a liquid dechlorinator or letting it sit out in the sun in an open container for 24 hours. It will naturally evaporate out of the water. After doing so, then you can add it to the system. The water pH needs to be close to 7 as possible. If your water's pH is high or low, you can purchase fish tank pH liquid regulator. Also, you can use things such as vinegar or iron sulfate fertilizer to adjust the pH. I would recommend putting some water in a 5-gallon bucket. Adjust the pH there. Then transpose the dosage to the size of your aquaponic system.
Before closing, if any of you need any nutrients for your system and can order products from the USA, I would highly recommend contacting "The True Aquaponics Store." Roger and his wife are great people, and they are there to help you!
