Backyard Aquaponics
A place to discuss aquaponics

Okay today I tested again.
zero ammonia and zero nitrites... . what the..?

Maybe the system is cycling or maybe its that I overfed?
I've cut the feed down and I've put about 8 handfuls of salt in the tanks.
There is some flashing going on.

latest readings
HORAY THE NITRATES ARE BACK!! after a summer of tomatoes and silverperch there wasn't any.
I'm also seeing flashing on the bottom of the tank.
Fish are smashing the feed though


Some deficiency in the Brussel sprouts. (added some chelated iron)


Some deficiency in rhubarb


And look at my cute little tube thingy.
I've found that the outlet is too small - will have to make it better. ATM the in flow is just right and the outflow is just right - a little bit of siphoning action going on

Me and the woman were just talking about bringing out the tube thingy. I think it works good after the media....she likes it before the media.

Before the media can be bad for the roots... Unless it is still after a filter.

Hang on is there something fishy going on here?

Of course.

My system is going well
A few things going on.

Some flashing - possibly overfeeding or some toxins in the water.
Some aphid problems in the greenhouse but spraying with garlic spray

Fish are eating well - temps are staying around 15+ I had one jumper a trout yearling .

Here is the jumper
It was the gap between the top of the rail and the fish tank bladder - fixed with some camping mat folded in.

Update

I've got some red spot on a jade perch - not sure if hes going to make it. Might be ICH as they are occasionally flashing but all the trout look fine. Or it could be some wood oil that's gotten in the system.

The NFT


The new beds

Hiya Jay, a couple of questions about your PVC tubes. What media are you using? Is it constant flood? And what are the feed and drain configuration?
Cheers,

these spring onions had been growing since spring - still tasty and only just starting to grow seed heads

Um yeah Jay, I already knew the rest.
I'm looking to add 6mtr of it to one of the systems and am gathering ideas and information.
Any advice would be great, do's and dont's sort of thing.
