Backyard Aquaponics
A place to discuss aquaponics

mine came out today. tank is now at 25deg

hi gang. i still have about 20 trout left and they seem fine in the heat so far. the tanks has plenty of shade etc. anyway i was wondering....if i took a few out, would it stress out the others and make them more sensitive to the heat? would i be best just to see if i can ride out the next couple of days? don't really feel like harvesting 20 in one night. thanks!

NW you wont have any problems removing a few at a time
if anything it would be better with fewer because you reduce the ammo levels in the water

Well we got up 2day and had some floaters
so out came the rod now all trout are chilling out in the freezer
Its BARRA TIME

In with you rb only place I have foun yearlings is golden ponds... Where you getting yours from?

41 under shaded pergola here yesterday

Just wondering how long Barramundi can go with no food? they would only be between 300-450grams, 17/18 in 2000L tank. My water has just started to go green, it's not bad, but I do like to see the fish when I look in the tank! I have already put 90% shade cloth over the tanks, they see very little sun anyway. I changed up to 8mm pellets two or three weeks ago, so I think I just need to get the feed ratio right.

Good to see your on the ball with what you need to do Angel, the barra can go without feed for a couple of weeks without a problem. We've had Barra refuse to eat for 4 weeks or more in the past.

I am a newbie to all this. I have set up an IBC with growbed planted 2 months or so ago. Have been trying to get the fishless cycle going before getting fish. Has not happened yet, but have had probelms with too much tinkering and some algae. I even emptied all the water and cleaned it as best I could without climbing inside!

I then refilled it and instead of dark green on the sides the whole body of water has turned green. We have had some heat and also lots of rain.

Should I cover the sides of the IBC and make it dark?

Should I just get some fish anyway?

Should I empty it all out and start again?

Please help, I have no idea and so far winging it is not helping too much

Thanks heaps

Got any pictures Rosie? That dark green on the sides is good, that's biofilm and you're best off leaving it rather than removing it...

Drat, I should have left well enough alone then

I will try to get some piccies.

Thanks

I'm in Perth, WA...is there a quick-fix solution I can throw in the pond...to rectify "green " water...without upsetting the trout/marron / plant bed...?

Barley straw.

Cover to block out sunlight, stop feeding and pump fulltime. Algae cannot survive without nutrient and sunlight.

Note that when algae dies off it produces a substance that inhibits further algal growth, at least for a while. This forms part of its natural 'blooming' cycle. I think the secret is to allow sufficient sunlight and nutrients that the algae remains in balance with the rest of the system, ie neither blooming nor dying en masse. Trying to starve out algae only means your vegies will suffer. They too, 'cannot survive without nutrient and sunlight'.
