  7. So I'm not the only shorty using a huge step ladder to reach the 6ft up the top of the 3 tier (keep hitting my head on the ceiling too) and also dunking my armpit in the marine tank when trying to relocate things (which no amount of sleeve rollups stops you getting soaked and smelly).

  14. Currently consider 2 IBCs, one for red claws and one for perch. Each would feed it's own hydroponic system. Avoid bacterial/pest issues from mixing on one system. Also gives me room to make one more suited to flood/drain trays, other running continuously as NFT. Red claws don't like strong flow. Whereas it might be better for the fish one to have current. A red claw supplier sent me this advice: " You should be able to stock them for such a purpose – stocking rate - good rule of thumb for stocking density is for every 10 kgs of crayfish you have 1000 litres of water . Use netting in your ponds to give them habitat and to allow them to use the entire water column. Over stocked tanks and ponds will lead to poor growth rates irrespective of quality genetics and good water quality. obviously some form of aeration and a biological filter will be necessary in the stocking ponds as well. " PS. 100g cray is edible, so I could stock 100 adults in the IBC (or a range of sizes is my intention, with 20 brooding stock). Haven't determined number of perch per IBC ?
  15. Feedback from Seqfish (supplier for dams): I would not recommend either of the cod as one is cannibalistic and the other is slow growing. Silver Perch or Jade Perch would be my suggestions. Jades grow quicker but as they are a tropical species they can suffer from issues throughout winter. Silvers are as hardy as fish come, but can take several seasons to grow to a table size. They are near indestructable though. So Silver Perch it is I guess Though I am currently experimenting with yabbies...put some feeders in a tub and without oxygen/water pump, sitting in sun, so temperature variance is up/down too....they survived 1 week. From feeder size to blue nearly 3 inches. Tough buggers and fast growth....yummy.
