Water Aeration Puns

Hello, I'm attempting to design my first aquaponics garden and in the various books I've read oxygen levels in water play a import in role in plant development. According to the Wikipedia article I've read regarding "fine bubble diffusers" this seams to be a hotly debated topic but the content is different. The article seems to focus on sewage treatment and the differing opinions seem centered around the bubbles' ability to properly rise and aerate the water due to the human waste in the water. Since I will be using a mineral salt based fertilizer this will not be a problem which means that the micro sized bubbles will presumably have a higher performance in my situation than in a sewage tank. With that being the case, what would be the ideal size bubble for maximum aeration? Any assistance would be greatly appreciated. Thank you :)

Hi Y'all,

Last summer I turned one of my railing planters into a hydroponics garden and it worked out really well. I had great yields. One of the issues with my setup was that my basil plants started to rot at the base of the plant in the later parts of their lifecycle. This made the plant unstable at the base. I chalked it up as a lack of oxygen in the water.

While I did add water and nutrients a few times a week there was no air pump in this set up. The reason being my apartment balcony doesn't have an electrical outlet outside.

My question is what can I do to aerate the water without a pump or the use of electricity? Does something as simple as a few snorkels work? My other thought is plants that naturally aerate water like in ponds.

Any advice is appreciated. Thanks!

Hi there. We have recently installed evaporator for treating the wastewater(MVR based). Condensate TDS came out to be less than 30 ppm but had very foul smell. in order to eliminate odour, we tried aerating the condensate but its colour changed to yellowish which is what we have not anticipated. Can anyone tell me the reason why it did occur? What are other cheap alternatives to remove the bad odour, which according to our estimates is due to high COD content in wastewater(35000 ppm).

Here's the important link that shows the picture of condensate and videos of condensate when it is exposed to aeration?

FYI:- this wastewater was generated from yeast based bio-methanation process

I’ve got a guppy in labor that my male guppies weren’t leaving alone. I netted the first 4 fry and the mom and transferred them to a 3.5 gal cylinder vase I just had plants and some bladder snails in. The vase has the same water parameters and temp as her original so I figured it would be more peaceful for her until she’s done giving birth, then I’d transfer her back to her home tank and let the babies grow in the vase until they’re big enough to not get eaten.

I was worried about aeration so I’ve got an air stone in, but I only have enough tubing for it to sit in the top 6 inches of water (the water collum is about 20 inches). Is this enough to provide oxygen for the entire tank temporarily or do I need to buy some longer hose?

I was originally planning on letting the babies fend for themselves in my main planted tank, but I had a change of heart at the last minute. Now I plan to keep a few and give the others away.

Thanks in advance!

Located in 7B (Greensboro, NC) and it has not rained substantially in over a month. Ground is bone dry. Planning on getting down 1/2 inch of water the morning/day before I aerate. Is this enough?
