for a two hundred gallon tank, what size pump do I need to get?
is it better for a constant flow fill versus fill and drain?
Got my IBC crates and will be cutting, cleaning, and setting up system this weekend.
Want to make sure I have all the right parts.
I get the water testing kit at mcgukins?
All my neighbors are very excited to see our system up and running in the next few months.
As a newbie, my concerns center around the use of Styrofoam, and whether it has a chemical influence on the food being produced, both plants and fish. Styrofoam exposed to sun breaks down into a very fine powder, therefor would tend to spread to everything else around it. If it gets into the lungs during handling, it is my understanding that not only it goes deep, but also that the body has no mechanism to get rid of it, making it in that sense, similar to asbestos. It is also known that the greatest danger of plastics (and Styrofoam?) to the ecosystem is in breaking down into infinitely smaller pieces, eventually to be ingested in some manner into plants, animals and people, hence we all carry some already.
While my comments could come under several headings, as 'skeptic', 'realist', or 'negative', rather I am trying to see solutions, whether painting would work or using other material would be a better answer, as I am hoping to eventually use both of the plant systems. Other than that, my thoughts are to use ferro cement for the tanks, and would appreciate any feedback on that idea.
With regard to the concrete tanks, I was planning at least a two week soak for curing purposes before changing the water, and washing well with TSP (Tri Sodium Phosphate),followed by rinsing, then monitoring the Ph during the 'breaking in' period,of the whole system, which seems to take a while to get established, regardless. My thoughts are to go with either, or both the three barrel systems in the mean time, http://www.aquaponics.net.au/Chops.html, or,http://www.fastonline.org/content/view/15/29/, just to get started with the process. At this moment there's a four foot deep hole in the ground, waiting for the next move, and much more planning.
Hi Eric and TC. I'm just jumping in on this now so forgive me if I'm missing something, but why Styrofoam? Are you planning a raft system? I'm not a raft grower myself but I've seen them done with a thinner (1/2"?) flexible blue or pink board instead of the old flakey white Styrofoam. Seems much less messy.
