I've gotta say that my decision to put the tank in the shed instead of outside has been shown to be a good one already


...so you did gain some knowledge by inspecting other setups then, took you long enough to come around tho :lol:

Been doing a bit of work on the system late at night after work. Managed to instal sumps and do plumbing and tonight I hooked up the pump and got the whole thing running. At the moment I have it running on timer - 15 on 45 off, but will set up the autosiphon when I get the time to install and then adjust to make bullet proof (maybe the weekend). For now I just want the bacteria to start populating the grow bed. To help this along - I've dumped one of the biofilters hydroton into the bed (probably 15 litres worth). With that and the mature water pumping through - I don't think it will be long before it is in business.

These pictures are for Les. Whacked the autosiphon on today (you all remember Bella). This little mod helps the siphon stop (allowing free passage of air) while still directing most of the water down to reduce splashing out of the sump.

Here is a wider angled shot. No plants as yet (except a couple of chilli plants I had handy in some pots). The system desing is pretty much the same as my other, with continuously running pond pump in sump - running to fish tank which stays at constant level, excess water flowing to the grow bed by gravity. Autosiphon cycles the flood and drain action. The pump is int he sump that sits under the grow-bed (its a fingerling tank). To this sump I have connected a second sump to ensure I have sufficient water. These sumps are not all that big, would be less than 400 litres in them together. I cut a hole in the shed - through which runs the poly pipe from the sump to the fish tank, the 25mm PVC pipe from the center drain of the fish tank gravity feeding to the grow-bed and the power cord for the pump. The fish tank is in the shed ;-).

With this system I am running the drain from the fish tank differently too. Instead of having the water flow over the top of a standpipe in the cetre drain and having an outer pipe to make the crap get drawn up from the bottom, I have drilled holes in the bottom of the standpipe and just run the tank level at the same level as the pipe to the grow-bed. THis means I am a good 15 cm or so lower in the fish tank than I would normally be. This is fine by me right now, because the barra splash like anything when I feed them. Once I've organised something to keep the splashes int he tank - I'll convert to the other style of drain and raise the level of the tank water.

Thanks Rupe - next I will add another bit of PVC to direct the water coming out of that slit downwards, The cover will not restrict the airflow, because by the time air is being drawn at the end of the siphon cycle, the pressure has dropped and water won't be coming out of the slit.

BTW - bella is stopping just from the sucking of air through the air hose. I'm tempted to remove the hose, plug the hole and see if she'll stop when the water reaches the crenelations, without the need for an air hose.

B4 anybody says anything - I will soon cover the clear PVC pipe between the sumps to stop algae buildup.
