Hey KE14, take your (emergency) overflow back to your tank, then you wont be dumping good water onto the garden/ground.

Might also save your fish/pump if things are stuck for some reason and just pumping water continously

Great to see it happening down your way KE! Only piece of advice is make sure your plants are in a sunny spot. If it's too sunny, you can always put shadecloth over them. If it's not, your up the creek like me! Just not enuf sun.

If the fish are the focus in the system you can always plant ferns, or preferably shade loving Cyperus sp., and Juncus sp., and just plant the food plants in the sunny spots. These are two families contain species that are typically greedy plants and they live in submerged or riparian margin environments (or rather, opportunistic plants because they can sustain long periods of little nutrients but increase production rapidly as opportunity presents). They are commonly used to treat high nutrient loaded waste water in settling ponds.

That way they would provide consistent nitrate removal because you don't need to harvest the ornamental plants, and you may even get a frog or two move in :)

Thanks Janet Re the growbeds, I'm trying to squeeze as much as I can in. I might have to run another 150mm pvc along the top.

Yeah the overflow will return to the tank

Stu the plants will be in the sun, and the fish in (mostly) shade.

By the way... everything is looking really good (sorry I forgot to say that in my rant above :oops: ). Your definitely in the running for "most compact design award" :P . Your plans so far are very inventive with the sites difficult limitations :D

Looking good KE14 :D a good way to use up space.
Just a couple of ?`s If the 20mm pvc pipe is inside the 150mm pipe are you going to be able to access it eazily to be able to clean it and if you are having the water flowing down through the system (gravity feed after the first pipe) by the time the water goes through the first 2 or 3 pipes will all the nutrients be taken up leaving not much for the rest of the plants.If the pump is strong enough might it not be eazier to set up a manifold and pump directly to each pipe ensuring the nutrients are distributed evenly, then let them drain into a sump thats gravity feed back to tank?(either way the system looks impresive and good luck to you)

Don't worry about nutes dropping along the line. It doesn't happen

Yeah G06 I'll be able to disconnect it to pull it out to clean or remove roots. My reason for setting up like this is so that I dont get all of the poo deposited at one end of the pipe and maybe blocking it up. I think it was Aquamad who spoke about this happening.

you can always plant ferns

Great idea. That whole area was originally going to be ferns before I stumbled across AP. How big are the above mentioned ferns? I could possibly hang some pots over the top of the tank and somehow drip feed them from above. That would also put a little bit more shade over the fish.

ferns range in size quite a bit. I have ferns in my shady dirt garden that range from 150mm to 1000mm tall.

Any clumping variety of fern would be suitable, like standard fishbone maybe.

The other family names I mention beside ferns are types of rushes (Juncus) and sedges (Cyperus). They are grass like plants that usually grow along stream sides and on the edge of dams. They can be from anywhere between 30cm-1.5m depending on species. I thought these would be even better than ferns as they suck up any available nutes quickly (you just need enough bacteria colony space to convert poo to plant food).

When selecting make sure you choose varieties that prefer shade and partially submersion in water (that is waterlogging as opposed to water with High DO as in aqua) as some other sp. in more arid regions like full sun and don't tolerate as rich an environment (high nutrients).

Also be mindful that you will be providing an excellent environment for these plants, so any estimate of size on the label could be only 2/3 of the growth you will experience (my brother has a water plant that is only suppose to grow to 30cm ribbons, his is over 1m in a 4ft tank :shock: sorry can't remember sp. at moment).

Last thing then I will shut-up, many Cyperus sp. tend to be a bit sharp on the tips and have sharp ribs running up the leaves, where as Juncus are soft (mind you the frog like the Cyperus more for protection).

Shuting down ..............................
