Backyard Aquaponics
A place to discuss aquaponics

Power out today for an hr ish. First time the power has been off that long.
Hooked up a small battery air pump to the salt water tank.
Didn't do anything to the 650ltr glass tank. The fish stayed in a group on the bottom. DO is kept high in this tank with ABF's and bio wheels as well as a pond pump.

Outside system I also did nothing too. Fish didn't seem to notice anything was different. When power came back on I turned on a pool pump that adds a lot of o2 to the water just in case. Will keep an eye for any stress signs but I don't expect any.

Thought I'd have a go at catching a couple of the large silvers. Put a net in the water and threw some food in the water and waited for a fish to get close. After 15min of watching catfish swim in and out of the net and bump into the handle not one large fish would come near it. I could of easily netted a bucket of catfish but these are not eating size. Going to put the net in the water at feeding times to see if they get use to it.

Spot the GB.





Water chestnuts

beautiful, healthy plants Duff, well done. Makes my garden shame

Do you have artichoke growing in your AP system? If so cool, I'll have to try that too. We had some artichokes from the dirt garden this past year but the plants didn't survive the summer though I thought they were supposed to be perennial in my climate.

artichoke grows great in AP. First time I've had them in. They are also a good host plant for ladybugs(the good ones).

Well that would be because aphids like to attach them but that is what ladybugs and their nymphs eat so it is all good.
Cool, I'll be planting some artichokes in ap then.

3 bottle feed tonight instead of the usual throw feed at pool while passing.
Rush of catfish(30cm by wrist thickness) followed by goldies and smaller catfish. By third bottle the big silvers came up. Big suckers. Going to have to get some diving equipment. Noticed a little yellow on the side of a couple. May be yellow belly or a couple of the black goldies that went in with the original batch.

What exactly is a "three bottle feed" Duff??

I am guessing he sat there and polished off three bottles while he watched them feed, instead of doing the toss and run.

You could well be right Burnsey...

yea, I don't think the fish could manage the bottle openers or twist tops.

lol.

What is going on with all the bubbles in the bottom right phot?

Thats the ABF in the Cod tank. My way of running with a 9 to 1 ratio of water to media.
