Backyard Aquaponics
A place to discuss aquaponics

Hi
Just setting new system up, 1000lt FT steel tank lined with pond liner and 500lt BYAP Gb.
Flood and drain system. 3000lt per hr sub pump. Have timer coming on 15min every hour and draining for 45 min which all seems like it's working well and GB not completely emptying.

Have just dropped 20 trout in FT tonight and going to feed little each day( 1 tbsp) waiting baterial to build up in system. Also put additional airation stone in tank to increase oxygen levels.

Tested ph tonight
Ph 7.6
post other reading tomorrow

And pictures please Wal...everyone lurves pictures

I would suggest that you not feed... at all... until you test and post your readings for..

pH
Water temp
Ammonia
Nitrite
Nitrate

Trout this time of year? It must be very cool there during summer.

Test as at 6.30am
Ammonia 0ppm
nitrite 0
nitrate 0
pH 7.2
water temp 12 degress

No it doesn't get that hot here in summer - it might hit 30 a few times, i'm just going monitor the temp over summer

I imagine that if you have trout now they will probably be fairly large, a bit larger than a normal fingerling. So as Rupe says, keep the feeding right down... I'd probably not feed for the first couple of weeks at least, your ammonia will build up fairly quickly even without any feeding.

Yeah they are yearlings from Gavin good looking fish at about 150mm ish i guess

Thanks for the advice
how long can they go without food for?
Cheers

They should last a week no problems

Reading as at 7am this morning
temp 11
Amm 0
Nitrite 0
Nitrate0

Ph 7.2
Have not fed they yet!

Tested again this morning
Ammonia just gone to 0.25?

Lost three fish as they jumped through the hole in my mesh at one end - bugger

The first day

You've done a good job to get the hydroton to stay in the bed at that angle

Yep, you can leave them without feed for at least 2-3 weeks if need be. If they can spot a gap they make a jump for it, especially if there is water flowing in there from a drain, a bit like them trying to jump up stream....

Got the kids to feed them this morning - great moment for them (both i'm sure)
only gave a tblsp and tested water after work
ammonia still only 0.25

Only a very slight fall on GB must be the photo
Waiting for system to kick in - It's testing my patience! But so far so good -
