Pest Control / White fly epidemic
« on: February 10, 2018, 07:47:33 07:47 »
Has anybody been able to find a suitable fish safe method of controlling white fly in an Aquaponics greenhouse. Some of my beds are crawling with small(2mm) white bugs among the clay balls over the winter. I am sure as soon as it starts greening up they will be on the leaves etc so Best time now to treat I think.  I have thought about isolating each bed in turn water wise then treating with normal bug killer so flushed water is delayed going to the sump. I have ideal opportunity at the moment waiting for weather to warm before repopulating with fresh fingerlings. I look forward to any help offered?

Fish Problems / Re: Perch - the ideal fish if I could find any !?

Trout are fine in the UK. We did look at Perch and found a coarse fish supplier for them. However, went with trout and great. They put weight on very quickly far more so than Carp which we also have. Various places to get trout as well, we get ours from a fishery in Derbyshire, Lead Mill Trout Farm, (Approx 50p / 100gm fish) collected. They deliver but costs more.

Hi Craig
I am using an old donated party tent frame 6 x4m covered with steel sheeting to waist height all on concrete covered with UPVC sheeting. The beds are made from a wood support frame for strength with 19mm ply 8'x 2'x 1', 1 sheet / bed with some scrappy bits for the ends. Lined with pond liner works great and relatively cheap but uses the space well. I have 5 beds crossways and planning on having a vertical strawberry section against the other side. Sump tank running underneath all 5 beds approx 1500l. 2 fish tanks IBC outside with a spare for rain water catchment at the moment but I will have the autumn fingerlings in there later this year. Finding out this year what grows best in this medium as more used to soil cultivation. Toms and beetroot flying, cress + Pakchoi got burned by sun. I am hoping fennel, celery, spinach + sugar snap peas will do well. Meanwhile the Allottment has just been ploughed ready for all my other stuff just about managing to keep abreast. The AP unit is certainly a lot less work. I have just invested in 3 auto fish feeders for the 3 tanks, more than I wanted to pay but it then allows for holidays😀.
The initial trout bought in feb as 140gm fish will hopefully start to get to plate size by sept, some nearly there already. They do not seem to grow at the same rate. Lost a few over the year due to no mesh on tank outlets (my fault) and others somehow getting out of the tank onto floor? Running with basic solids filter at the moment, still making my mind up re how effective they are or if necessary at all.  The Aussie AP guy seems in favour of getting as much worms and fish poo into the beds as possible to make it more like a soil compost but with clay balls for drainage. I imagine with time the beds will mature to this state anyway as roots and leaves rot down. It would be interesting to see some much older beds to see if this is correct.Any way ,if you are near Brum, pop in for a glass of wine and a chat re AP.
Regards Steve Anderson

Hi Craig
They sound like monsters:) How long did they end up?  I have spent all last year cycling the beds with no fish, scrawny veg, too busy at work. Just stocked with 12x 6-8" and 50x 2-3" trout (separate tanks) and I am planning to mix in a few various carp (for tank cleaning and variety) which I am collecting Friday from Ripples (Telford). All set for a busy Spring/summer. Planning on a 3 tank rotation of trout 6months apart buying in 50off  (50mm) min size as they are the cheapest. Just got 50 for £15 from trout farm in Hathersage in the Peaks.

Hi crazyducker
I am based in East Birmingham  as well.
I have just about got my system ready for fish, going on holiday then its fish fry time☺ Getting  the syphons to be consistent has been a struggle but now sorted. Plants growing fast in the growbeds needing fish poo methinks!  Have you got any trout fry or is it all Tilapia?

Thanks Titus
Another  question  I am afraid.
Where people have used made up growbeds and used a liner etc, what sort of material  have they used?  I have looked at proprietary  pond liners and they tend to be quite expensive.  Has anyone used  building damp proof  membrane instead? I found some the same thickness and what seems a similiar  spec  but a fraction of the cost.

I was wondering how you  did your syphons from a bulkhead fitting which tend  to finish flush to the inside surface?  After a very interesting visit to Craigs setup, it confirmed  to me to make the grow beds rather than top and tail an ibc and use a wood framed Gb and a liner. Hence the bulkhead fitting needs to compress both bed floor and the liner to seal then stand up by 230 mm. I forgot  to ask at the time.

Thanks Aquaveg  ☺
I am a bit concerned  about using welded joints in case it needs cleaning or mods. I suppose  inspection ports or Tees with a blank allows for a bit of maintenance. I am looking at the Effast range, relatively cheap and good range of fittings. Suitable for potable water.
Thanks Steve

I have just about finished the polytunnel need to start making GBs and design plumbing. The system will eventually consist of 2 x 1000l ibc FT with a 200l biofilter, 5 x420l Gbs and a 1500l sump tank, (5.700l total). I am aiming to start with one ibc FT and 2 or 3 GB this season and gradually increase the plant loading as the fish grow.
I am looking for some feedback on the best type of piping and fittings to use. If the piping needs to be cleaned out on a regular  basis, I assume pushfit fittings would be best?
I am looking at using 50mm pipe virtually throughtout to give less chance of blockages and smoother flows. Any recommendations on valves, pumps, aeration compressors etc.
All and any feedback gratefully  accepted.

Just getting my greenhouse and system  sorted,  4m x 6m polytunnel with 2x ibc fish tanks and 6 half ibc as grow beds. However,, wondering  what and where to get required Ph meter and any other recommended test kit. Any suggestions welcome.. I would love to have a look  at an established  system  within an hours journey if possible. Any offers gratefully accepted☺
