    Hello,  This is a day for filters.  You are the second person talking about cleaning the fish tank.  I built a sand/sock filter that was easy.  It is to get out the small micro solids that discolor the water. It seems to be working well but it has only been a day and a half. I am using a small 70 gph fountain pump. I put it up on You tube so if you can't find it I can put up a link in case you are interested.  I plan on cleaning the sand every so often by exchanging it with new sand and sterilizing the old sand. 
    I had to laugh at your comment about your fish being like your dog..can't eat that!  I sometimes feel the same way. I have not eaten any of my Talipias yet because they are just a battery to grow the plants. 
    Your system is looking good.  I like your use of the washer sensors...that is really cool.  I may have to get you to tell me a little more about the technical way it works.
    r,

    Hi Jim,
     
    You'll quickly begin to experience dropping pH as a normal feature of operating a recirculating aquaculture system.  While it also happens in an aquaponics system, decreasing pH is largely offset by the denitrifying impact of the plants in the system.
     
    Without plants, you'll discover that pH drops much faster......to the point where you'll be adding something like calcium hydroxide (builders lime) at very regular intervals.  In fact, the easiest way to way to manage pH in a RAS is to do it on a daily basis.....by mixing it with your fish food.  
     
    The amount of lime is proportionate to the fish food being fed each day.
     
    If, however, your source water is alkaline, that might help to maintain your pH....but unless you're drawing water off your RAS (to supply your plant system) at fairly frequent intervals, you'll find that the pH will drop over time.

    Hi TF

    From a purist point of view... The problem from recirculating any unfiltered water anywhere in an RAS is you are grinding up any solids to finer and finer solids....The idea is to remove as much solids as possible in the first place to stop this happening...

    Lots of people will try and convince you otherwise...I say give both the theories a try and come to your own conclusion of what you like...Or just choose the one that stacks up to what you like...For me...I like to remove as much solids as I can ASAP...

    Cheers

    In the application we have in our greenhouse at an orphanage in Honduras, the goal is to produce as much food as possible in the space we have where it is located.  72' X 22'.  There is a 52' X4' , 4500 gallon fish raceway. The vertical towers for the most part are suspended over the raceway.   This way there is little space not used for growing food, and it also shades the raceway a bit while providing some aeration.  The rest of the greenhouse is filled with growbeds  containing gravel media, which is what does the bulk of the filtration.  We have redworms in all our growbeds and the 60 towers. The towers are only 3' long to fit the shorter stature of the Hondurans, so they can safely reach out and lift and replace towers over the raceway.  This all provides balance and filtration needed.   
        Towers alone would not work well in our situation, but they are important in being able to grow more food per squarefoot, taking advantage of the vertical spaces. We have a combination of towers and growbeds to form an operating system that remains healthy. The towers have remained rather easy to maintain, using Nate Storey's method of daily procedures. 
        The vertical tower debate I am sure will continue.   But in our application, they are a great component to our system, and perform well. They are not towers that were bought.  We fashioned them out of gutter downspouts on site.  We could have used matala media, but opted for the black fish pond filter media ( Comes 2" thick, and in 4' wide rolls - it is light) so we could fit A LOT of it in our luggage to transport to Honduras. 
       Hope this information adds another constructive bit of input to the discussion.

    Hi ROZ
    I didn't know it was the "NEW" hot topic You got some other links to any new forum discussions ? I'm not on Face Book
    I think the reason or need for vertical growing is easy explained in, lack of  space (urban/city)
    Also the Idea of covering building walls/roofs with plants  creating "green lungs" have been high on the agenda in city developement for years.
    I see it as a good idea, if one also, can incoorporate producing food even better yet.

    Well, not sure who the "us" is you are referring to here. Shortage of food has always been with humanity in some form or another in some location or another. It is not a new phenomenon. It is however more apparent with modern day instant news. 
    Allow people to do what they need to do and they will usually feed themselves and others.  Governments usually screw things up... Case in point.. Lets go green and pay farmers to grow corn for ethanol. Now there is not only a shorter supply of corn used as food, but it is more expensive because farmers are incentivized to grow it for fuel.
    Look at the former USSR. A controlling government that could not feed its people where store shelves were bare because of the actions of the communist government directly. And on and on...  IDK, who is going to feed the starving? The starving will have to learn to feed themselves. The information is out there. It comes down to the political climate and ability of the populace to be able to do it in a stable environment.  
    So, can we feed the World, or should I say can the World feed itself? Yes absolutely. Can we assist those in need to learn the skills to feed themselves? Sometimes, but not always. If the World would abandon its madness and come up from the violence long enough to build the things that are needed, then yes, they can feed themselves. But first each nation needs a stable environment, the will, and a benevolent leadership.
    Or not. I may add that at the rate people are killing themselves in some nations through never ending war there won't be a population growth in those regions.

    All that aside....NASA has revised their earlier models and admits they made mistakes.  There is no computewr model that takes all the variables of climate input into account. For example, in many computer models water vapor in the atmosphere was not taken into account...That is not science, it is hysteria.
    Man made model simulations are not factual evidence of the real interactions of climate...they are best guesses at best.

    I agree, both arguments are suspect. All I have ever said, and is as true now and when I first said it is, there is no scientific proof that man's activities are accelerating GWing.
    That does not mean we should not be cleaning up the lands and oceans and being more aware of what we do that may harm the environment. That should be a given, warming or no. 
    But if anyone thinks I am going to allow the government, the same government that repeatedly lies to the people that elect it and pay their salaries, to impose a carbon tax on a theory....well forget it!

    Didn't 99 % of scientist at one time believe the Earth was flat?

    Science is settled!
     
    97% scientists agree!! ... except for folk like Lennart Bengtsson (http://en.wikipedia.org/wiki/Lennart_Bengtsson)  ... http://www.breitbart.com/london/2014/05/14/climate-science-defector-forced-to-resign-by-alarmist-fatwa/
     
    Further debate is equivalent of rejecting physical reality.... Wow... Doesn't this, that is the statement "further debate is ridiculous", going against the core fundamentals of Science?
  12. crsublette liked a post in a topic by Strider in Can humanity feed itself without destroying the biosphere?   
    Yep, and I may add that compared to the "greenhouse " gasses expelled by nature, mans contribution is miniscule.
     
     
    Nothing will stop those nations's industrial revolution. They do not have the same political "science " we have concerning GWing.
    The Earth is billions of years old and if anyone thinks this climate is unique I think they have ulterior motives.
    Let's take that money we waste on fighting so-called GWing and use it to increase food production through research and farming support.

    Hi
    To buizzi to really read this thread last summer, kids home from UNI friends visiting...... . non or litle time to spend online then
    I'm 100% with Sam here we can if we will
    it's a matter of deciding to do it, untill then I'm doing my part, and no one can stop me

    Indeed... as history has shown... as our knowledge grows, then so do our efficiencies and innovations of acquiring, processing, and consuming...
     
    Fortunately, not a single biosphere nor resource nor climatic nor disease outbreak calamity forecast have come true... Remember... Now it is called "Climate Change" rather than "Global Warming" or how about that non-existant over-hyped Ebola scare. Why then all these 40 year+ predictions? Marketing and Money for the "cause" so to do their best in skewing the scientific method to disguise their confirmation biases, which is comparable to the unethical business practices of agribiz. Al Gore sure is loving the windfall profits. Environmentalism sustainability is a parody of Judeo-Christian theology and their forecasted calamities is the content of their Revelations. 
     
    Quite sad when folk lose hope and faith...

    BTW Ande, I did not understand your "airstone" comment till today as I was looking at the air pump. For some reason I thought you were talking about my water (pond) pump.  Actually I have had water flood those little aluminum air pumps and no ill effects.  They are great little pumps, but I do keep them over the FT now...thanks.

    Where are you getting this information?  What makes you think it is not profitable? 
  23. crsublette liked a post in a topic by Strider in The UAE Project   
    It is a matter of perspective. It is sustainable as long as the government wants it to be...that is, as long as they or someone are willing to pay for it.
    But the scale is important too. The bigger it gets, the more profitable it becomes. I honestly have no idea if it pays for itself...seems like it would given the facts:
    -cheap labor
    -cheap power costs
    -mass production of greens and fish
    -cheap water.
    In most places those are ingredients for success.
  24. crsublette liked a post in a topic by Strider in The UAE Project   
    Hi Gary,I can think of no better place to test the production of food than in "inhospitable" areas. For if we can succeed in these volatile places, then we are better prepared to grow food if we do destroy our ecosystem as some think we are doing.
    Anyone can grow in the lush rich soils where water is abundant but the real challenge is in areas where conditions are less than ideal.

    I would imagine that the cooling of the greenhouses is being done with swamp coolers. The same way houses are cooled in the high desert regions of The US. Basically water is circulated through some sort of material and wind is forced through it effectively cooling the air as it moves through. This works surprisingly well as long as the outside humidity is very low. We used to fill canvas water bags and hang them on the grills of our cars to cool down the radiators. As air passes over and through the bags the air is cooled. Same principle.
