Why not post a sketch of your planned system, that helps us visual learners work out things better. Oh, and what kinds of pumps (LPH)?

HI aquamad I am thinking of two pumps for aeration like large bilge pumps.then one in each tank to the grow beds and one in each pit at the end of the grow beds they would be the largest this way I can have one or both tanks going at the same time |

Just a small bed heh. Ideally you would use potable water pipe, like that which is used in the walls of many houses these days. |

Hey Trev, a couple of points I can see from your sketch up design so far. Firstly, if you are burying your fish tank into the ground, then you may have no need for a drain tank, slope the growbed back towards the fish tank and use gravity, with only one pump... Second point, thats one hell of a long growbed  I can see that it would take a long time to get the water from one end to the other and you may run into problems with flooding in the bed, unless you encorporate a few more drains along the length of the bed.. I think that just one drain at the end, and water having to flow through 19 m of gravel you will have some troubles... Also, you need a bit of fall in the growbed so that it drains, over 19m the far end will have to be pretty high up.....
Any chance of dividing your growbed into smaller beds for the design? Food for thought..... |

I can see that it would take a long time to get the water from one end to the other i have a growbed 4 ish meters long half filled with bean gravel (10-20 mm in size) and it takes about 20 seconds to get from one end to the other, and its on a steepish gradient (about 30 degrees off the horizontal) just to give you abit of an idea of how long it might take... |
