for most aquaponics applications it is likely unnecessary to use a reverse osmosis filter, but there are occasions where it is necessary. Check out the video to find out…

Written by The School of Aquaponics

We are here to push the movement of aquaponics in a forward direction. Our primary focus is help you in your adventure with aquaponics by providing you with the highest level of information. Aquaponics is still in its infancy and we predict that it will be the go to method of farming by many families and urban farmers. Our job is to ensure that they are taught correctly.

  1. Thank you so much for the response, helped a lot.

    I have another Q, here where i am round fish tanks are non existent, one option are the water tanks (cut the top off) but what about round Intex Pools with metal frame? Can those be used instead of Carbonfiber or Plastic fish tanks? What diameter SLO would work for a pool of 15 foot diameter?

  2. by the way, i recommend blending RO water with tap or well water to achieve the starting water conditions you like. my tap water is 470 ppm and about 8.5 PH. I haven't tested what minerals are present but I had to use loads of acid over weeks to strip the alkalinity and get a good starting tank for my hydroponics reservoirs. Also there was hard water salts in the bottom of my tubs after I got the ph stable. In my case they were non-circulating so it didn't matter but all that stuff could easily gum up pumps filters and pipes. I found that I can blend the tap water with RO water to about 150 ppm and i still have the PH buffers and minerals from my local source but they are more manipulatable through adding adjustments. I know you are pushing using the natural aquaponics process instead of adding acid to find balance but I don't have fish at this point so i have to add more manual influence to get what my plants need.

  3. another good one.. I have to admit something. today talking about the ph levels and alkalinity between the raft and the NFT. Not sure if I actually caught the vid when you cut the NFT in and was looking for it in your channel. (I believe that I have seen EVERY SINGLE ONE of your vids.) went all the way back to when you went to visit AST and didn't see it anywhere. my question with regard to that is, are you running two separate systems to keep the levels different? one system for the NFT and one for the Raft. .I have heard that this is a must (from you and others) depending on what you are growing (and how) so was looking for the vid that showed the install of the NFT..

  4. This is random but can you use aquaponics to grow flowers as well? Have u ever thought about making money on the side selling flowers? I mean u pretty much got everything you need haha

  5. Hello Sir . In our city in saudi temperature go up to 47c some times . Can you please tell us how to cool the water and environment for green house to achieve growth for most of vege greens that only grow in 26c or less . Thank you

  6. So a way to combat hard water in raft bed systems, I can have higher stock and feed more? Should I then up/over size my bio filtration to handle the increased fish waste?
    I am laying out my newest system and have hard well water. I also have a 300 gpd r/o system. But I'd like to get away from using it. Cause if the high waste water it makes.

  7. This is some of the lesser known and harder to find info! Killin it with this video, THANKS!
    Please do, do another video going deeper and spend an hour explaining it more!
