<p>Another consideration would be the use of strawberry towers, they will need more power to lift the water up to the top of the tower that changed things considerably for me. I agree bigger is better since I went through 4 sizes before I found one that could reach the top of my 6 foot towers.<a style="cursor: pointer;"><img src="http://www.bkserv.net/images/Tongue.gif"/></a></p>

The answer depends on your stocking density, feeding rate, water temps, species, and system design. I have seen a fantastic design running 1800 gph or less, moving water through a 5K gal of FT, 4K sq ft of DWC, and 1000 lbs of tilapia. That is much less than the standard, which is 1 FT volume per your, yet it performed great.<br />

When planning, consider head loss, and gunk loss, and pay the extra $ for pumps. This is a good one here…

Gravity drains should be at least twice the diameter of feed lines.<br />

F&D should both flood and drain completely at least once per hour, though moderate climates can get by on less frequent doses. I agree that Larger is better…tag:aquaponicgardening.ning.com,2013-06-21:4778851:Comment:4874072013-06-21T19:16:44.659ZAaron Brookshttps://aquaponicgardening.ning.com/profile/AaronBrooks
<p>I agree that Larger is better. I have never had an issue with Pondmaster pumps. Don't worry about the pump moving water too fast. You want to have the power to run multiple beds and instead of restricting the flow with a ball valve, you can divert the water flow with a T fitting to a spray bar. The spray bar will aerate the water in the FT and then you won't be restricting the pump as much by closing off your pipes.</p>

<p>Larger is better, but larger costs more to operate. The initial price of your pump pales in comparison to the cost of operation so look for efficiency.</p>
<p>My experience shows that the water flow is not critical. I'm not saying a trickle is going to work, but I ran my 800 gallon system for months at about 200 GPH without any problems. My density is about 37 lbs / 800 gallons total system volume which is pretty low in comparison to many other systems. So it probably hinges on the…</p>

<p>My experience shows that the water flow is not critical. I'm not saying a trickle is going to work, but I ran my 800 gallon system for months at about 200 GPH without any problems. My density is about 37 lbs / 800 gallons total system volume which is pretty low in comparison to many other systems. So it probably hinges on the density you intend to maintain. My low density might not work for some plants that require more nitrogen, so what you intend to grow also comes into play.</p>
<p>But to be safe you should probably just follow the <a href="http://community.theaquaponicsource.com//page/aquaponic-gardening-rules-of" target="_self">Rules of Thumb</a> document until you have more experience. Don't worry you will have an opportunity to replace your pump before too long. They don't last forever. Even the external pumps wear out way too fast.</p>
