    I know a lot of Koi breeders use small portable swimming pools to grow-out fry. One guy collapses them and stacks them away for winter and uses kiddie pools about 1.5M diameter. Maybe 60cm deep.
    I have kept Endlers and Cherry Shrimp in large tubs over winter. A north facing position gets maximum light in winter and avoids the worst heat in summer. A glass lid helps a lot in winter because the sun shines through the glass and heats the water but the glass is not a good conductor of heat and keeps the temp up longer.
    My favourite semi emerse plant for tub or pond start-up is Watercress.Buy a $2 bunch at the supermarket and hang the cuttings over the edge with the cut ends in about 2cm of water.Roots in a few days and makes a great Nitrate pump and fry saver.

    Is anyone growing java fern amor bolbitis in their outdoor tubs?

    I re-scaped my big tank recently and I have a bunch of NL Java and bolbitis I would like to save for a future Scape.

    I could set up a spare tank to hold the plants until I'm ready to use them, but I have two tubs sitting outside I could throw them in. I'm just a bit concerned about the temperature and might level fluctuations - has anyone grown these plants outside before?

    Cheers

    I have struggled with Java outside in Sydney (although it didn't completely die) but my tub was very small so may not be a good example for you.

    Thanks Rebel, do you think this was due to fluctuating temperature?

    Perhaps but maybe it didn't receive enough light? Not sure. I was able to grow emersed Mint and water cress without issues though.

    Ok cheers. If anything I think mine gets too much light, I've had to double up on shade cloth.

    I've thrown a clump of each plant into a tub as a test - I'll post results soon.

    I've only got my mosquito breeder this year. Maybe I should start a late tub.... Don't have a great location with power available. It's best if you can at least run a sponge filter I reckon. Some water movement etc.

    I don't have power where I run my tub so I built a small 60W solar system to power an air pump 24/7 for the sponge filter.

    Haha. I'll send you a pic this weekend if I get a chance. You should have come have a look when you were up here.

    I think this is fine, my air pump is in my garage next to the power point, then I ran a 10m hose outside to my tubs.

    wait what?

    Any further information? Very keen on this build indeed!

    Cost me around $170 to build this.

    Bought new from eBay: 60W solar panels, 10A solar controller, cabling and connectors (i.e. twin 4mm2 solar cable (proper solar cables to withstand UV/outdoor elements), anderson style plugs, mc4 connectors, 10A inline fuse, 15A twin sheath auto cable, ring (eye) terminal connectors).

    Bought used from eBay/Gumtree: 60AH deep cycle battery, battery box (to protect from the outdoor elements).

    DC 12V air pump can be bought for cheap ($2-$3) from eBay.

    My rationale (to my wife) is the solar system can easily be moved to the car for weekend camping trips.

    The outdoor tub will do fine without aeration/sponge filter for a couple days easily. Else, I can just get a second deep cycle battery dedicated for camping trips.

    Sorry sweefu for going OT. I have tried to keep this short.

    Rebel, send me a PM if you would like more details e.g. links to where I bought the items, calculator tool to determine the battery size you need to run your electrical items for X number of days without sun, etc.

    Hi all,

    I hope everyone is having a successful tub season.

    Last night it got down to 11 degrees at my place so I'm planning on shutting down the tubs soon.

    Can anyone share suggestions/tips/experiences for how to catch all the fish/shrimp? In both my tubs there are a juvenile rasboras and lots of shrimp. The water isn't crystal clear and trying to net them all seems impossible.
    Is it just a matter of slowly draining the water (perhaps through a net) and catching everything you can?

    Cheers

    I siphon out most of the water, remove the plants and then run a big 12 inch rectangular net through the tub many times before finally straining the whole tub. I like to dry them for a few weeks before setting up again to kill of any diseases, parasites or snails - over winter I try to find some water with daphnia (ringwood lake) and seed the tubs hoping for a population explosion that I can use to feed other fish before next summer season.

    My 1000 litre glasshouse tubs are still 25C so that experiment is working well but the blue-eyes have stopped breeding. I took the adult honey blueyes to the LFS and will raise the fry over winter in the glasshouse. MY 8 breeding gertrudae seem to have turned into ~30+ so thats OK too (because I didnt have to pick the eggs!) P. furcatus = 4 females and 2 males gave rise to ONE fry. ...pathetic.
