Backyard Aquaponics
A place to discuss aquaponics

Cut your holes the correct size first go for your desired pots. I had holes pre cut from a previous project and the cups don't fit - so I can't use a hole saw as there is nothing to stabalize the drill bit in the middle. Will have to jigsaw them or something.

Do what blind freddie did with his elbow outlet - make sure its nice and big (as well as the outlet pipe). And you can turn and adjust the level with it. I used 13mm as I had a bulkhead fitting at that size and its too small (I have to get the in-flow just right).

Have a tap on the inlet to adjust flow.

Use 100mm + pipe

Sump water isn't necessarily going to be totally clean - I'm getting solids build up.

Nest a hole saw the same size as the hole inside a hole saw the size you want to drill. The inner hole saw will act as a pilot bit for the larger hole saw.

Ahhh brilliant idea thanks !!!

Very brilliant!!

Systems looking great jay!

That is one of two techniques that boat maintenance workers use to enlarge thruhulls on boats. The other is to pound in a damage control plug and use that to guide the pilot bit. You would go through a lot of DC plugs trying to do that on an NFT pipe...

Jades in the hospital tank @14ppt salt.
Silly me used too hot a water and the fish went upside for a few hours - they are okay now.


You can see the red spot on his body


And here are some trout fingerlings that are getting big


NFT is rocking!!!

Looking great, is that Bok Choy?

Jay, how long have those Bok Choi been in the NFT, looking good , I've just recently planted leafy greens in my DWC and they seem to be traveling well so far

Bok choy - not sure - but its growing quicker in the tube than the growbeds. possibly the sun.

Silver beet is dooing well with the salt I have in there (5ppt?) but not the broccoli and brussel sprouts.



Vietnamese Mint


Tomatoes in Warragul during July


Tarragon (mexican)


Silver Perch - sexy looking fish with black bands and large spiney dorsal fin that comes up like a marlin. And some trout, which are getting bigger - hope they don't eat the little perch.


The expansion is powering along - loving the NFT.



Asian green seeds up!

Coming along very nicely mate, those plants are really loving the NFT!

Things are growing ok







Someone gave me some asian greens - sprinkled and here are a few varieties




A Kale Cutting

Had a couple of random deaths - not sure why

4 more deaths - all about 8cm long.
