Dear Friends,I got my system (Aqua Abundance, 2 media and 1 DWC, with a 500 gallon fish tank) eight months ago. I believe it is fully cycled because the ammonia is a 0.5 ppm, the nitrite is at 0.0…Continue
"Thanks for the video suggestion. Can you give me a URL? My TDS and EC are increasing every time I take a measurement. They have not stabilized yet so I will wait and see. My 24 diameter geodesic dome has four windows and a double door and everything…"
"Thanks Jeff. I will see how it goes. I am noticing a very gradual lowering in pH as time pases. My real question is which test to believe. The API water test kit that I got from The Aquaponics Source measures pH of my 500 gallon fish tank to be at…"
Thanks for your information. I was researching on line and found the attached document that gives me greater clarity of the significance of TDS and EC. They can be used to determine kH (Carbonate Hardness) water hardness and general pH…"
"Once per week I water all my soil plants with fish water (water I take from my 500 gallon fish tank that has been filtered and nutrient balanced. The rest of the time I use Chlorine free water from the garden font.
"Since the end of cycling for my 600 gallon system I have always had Nitrates over 160 ppm. Nitrates are good. If you are worried, plant more plants. The system should balance out and not require a lot of tweeking. I am a pilot. If you steer by the…"
"I add about one tablespoon of a micro-nutrient solution (that contains Potassium and Calcium) about once per month. It and Chealated Iron seem to work for me to avoid the yellow tint. I have noticed that an inadequate amount of CO2 will cause what…"
I am confused as to the value and significance of TDS and EC and their relationship to aquaponics health. Generally what I have read on the internet is that they are general measures of water purity. Aquaponics water is never pure…"
"My GH is screened in the summer and I use a wood burner in the winter. I never worried too much about co2. I'm no expert but 220 TDS is low. I know in hydroponic setups they run 800-1200. Why do you get 2 different readings on your PH? I use…"
Thanks for your response.
I have a current copy of the local city water quality report. It says that the only thing the city adds to purity the water is Chlorine. Eight months ago I bought a Chlorine filter from Amazon and installed it on…"
"I sympathize with you Tom. My system worked great for a year or so then I started having the same problem. I had the water tested at the local university and found everything on the high side as far as nutrients. The thing that stood out was…"
My understanding is that to encourage beneficial bacteria you need a large particulate swirl filter, a biological filter, and a sump tank. Without that you may be limiting your system's ability to produce nitrates. I have all…"
